Potential external drive conflicts?

I'm trying to get an external drive connected to my iMac, but is intermittent and may be running into a drive conflict with a Network drive I have from the same manufacturer..
I have a Network drive (Western Digital My Book World 2TB - based on the size, I suspect it has 2x1TB drives in it) but too slow for working on video with iMovie. So purchased another WD drive 1TB (a Caviar Black 1001FALS), put it in a drive enclosure (Vantc NexStar 3) so I could get a Firewire 800 connection.
When first connected, worked like a charm. showed up, formatted the drive with the Mac, copied some files to it. Deleted files from it. Started moving iMovie files to it.
I came back 1/2 hour later to find the icon gone from my desktop and unable to get it back. Tried other cables, (firewire 400, USB, etc.) Rebooted the Mac. Rebooted the external drive, the network drive, etc.
Ended up taking the drive out and swapping out the drive for another drive - worked great - again. switched back to the WD 1TB drive and no luck.
Took the drive to the store I bought it from and asked if there was a problem with the drive - negative. Diagnostics were all fine.
brought it back and put it all back together. worked again. This time I noticed the network drive was not working. So, rebooted the network drive. As it was booting, I saw the external drive disappear again. Again not finding the right sequence to get it recognized again.
shut down the Mac and both drives. let sit for a while. rebooted the Mac. Then rebooted the external drive (1TB) and it showed up. Rebooted the Network drive and both were live for a while. Seemed stable. (Started moving files again.)
Came back again a little later and the External drive is gone again. And trouble trying to get it recognized again.
Any ideas MOST welcome!!

Hi, I had a similar issue with a WD ext HD..I tried a different connecting cable (wd/iMac-heavier gauge)Works like a charm..
Make sure it has the little resistor fitted...

External disc drive conflict

Hi, I have a MacBook Pro 2007, and I use some external drives as I do a lot of music recordings. So far I used three USB and one Fire Wire 800 device. When I added another Fire Wire Disc (Seagate 1T) in chain with the other Seagate through the Fire Wire, one of the USB disc disappeared from the external devices list. Stopping the Seagate and removed it, the USB disc appeared again. I suspect a conflict but I do not know how to solve it.
Thanks for any help!!!

Hi,
Actually any external Optical Disc Drive (ODD) can do, such as:

External Drive & Camera Conflict?

I just got FCE4 and Canon ZR950 last week. I have an iMAC with a MyBook external harddrive connected via the Firewire 800 port. When I connect my camera on the 400 Firewire port, FCE doesn't recognize it. If I disconnect the external drive, FCE will recognize the camera. Called Apple Support and she suggested I get a device (she wasn't sure exactly WHAT) that will allow both the drive and camera to be connected simultaneously. She thinks there is a bus conflict. Is there a way to use both at the same time without such a device, and if not, exactly what kind of device do I need? Also, I looked at the drive, and there isn't a way to daisy-chain the camera to the drive.

Connect the camera to your iMac. In FCE>System Settings, set your internal drive as your Scratch Disk. Then capture your footage.
Disconnect the camera and connect your MyBook. It's probably simplest to drag your whole Capture Scratch folder to the external drive. Then drag the original files from the internal drive to the Trash and empty the trash.
When you next open the project, you'll need to reconnect your media by showing FCE the location of the Capture Scratch folder you copied to your external drive. I don't think you need to change the Scratch Disk in FCE's System Settings, but I'm not sure.

New computer with lightroom 5.7 installed old computer has 3.6 installed.The new version has a conflict when trying to read the external harddrives.Old sees it as drive (I) but new sees it as drive(E).When I try to rename external drive it comes up as LaCie (E) (I) so I cannot get it to change the name for lightroom to read it with all the previous edits-please help all advice appreciated.

lotta stuff going on. I'm in the office now and don't expect a client for about 45 minutes. Want to walk thru this via skype or ichat? email me directly if you do. [email protected]
If not, post back and I'll try and walk thru these things.
Also, if you want to email me the project, I'll see if I can open it here.

Mac Mini conflict with Western Digital External Drive

My Mac Mini used to work fine with my 2 TB Western Digital external drive, but now when I plug it in my desktop goes blank and the drive won't mount. I have tried it both USB and Firewire. The drive DOES work with my Powerbook G4.
Any help is greatly appreciated.
Thanks

Hi-
Please clarify.
What mini are you using? One of the new 2009 models?
As for the drive, is this a Firewire 800 drive or a Firewire 400 connection?
If it is a firewire connection, are you daisy chained to another firewire device? If so, in what order is the hard disk?
If it is a firewire 400 connection, what adaptor/cable are you using?
For a USB 2.0 connection, are you connected to a hub, or directly to the mini? Is the hub powered or not? Have you tried a different USB port? Same results?
Did you plug in both the USB and Firewire cables at the same time?
What is the model of your WD ext drive?
When you say that your desktop goes "blank" what exactly do you mean? The computer is still on, but there is no image on the screen?
You mention that the drive works with your Powerbook G4. By Firewire? USB?

Install to external drive: good or bad idea

I have an iMac that is currently on 10.5.5. However, it was originally a Tiger install. I performed an update install to 10.5.6 and while it runs, I have stability issues that came with the Tiger -> Leopard update that I know I can eliminate by doing a clean install.
Of course, the problem with a clean install is that the total execution time is very lengthy (from install to last app license re-registered) and my workstation is DOA (or nearly so) until completion. And then, there's always the odd detail I forgot about that I have to research to find the answer.
So, why can't or shouldn't I do the following, or how to make it better?
1) Do a clean install to an external drive (I have a 500 GB USB drive I can use) Leave the internal drive intact until step #4.
2) Install the OS, apps and utilities until it matches my current machine.
3) Once ready, back up the internal drive to the external drive as a DMG. (BTW: there will be another time machine BU on another machine on the network -- so there will be redundancy.)
4) Do a secure 7-pass erase of the internal hard disk (this performs hardware-managed low-level sector checks, turning off sectors that error on read/write)
5) Use Carbon Copy Cloner to copy the external data to the internal boot disk
6) Copy my documents from the backup to the new user folder.
7) Viola! Reinstallation complete but I can access my data at nearly any time (latency depends on current task) if I must (except during #4)
Where's the fly in this ointment?
TIA!

However, is there a way of achieving zero-ing out defective sectors, like SpinRite, <http://www.grc.com/sr/spinrite.htm> without my having to remove the hard disk?
AFAIK, SpinRite does not actually "zero out" defective sectors in modern IDE hard drives. To better understand what it does (& in general the link between analog & digital data reading mechanisms in magnetic media), look beyond the brochures & study the “What's Under The Hood” technical note at http://www.grc.com/files/technote.pdf, especially the "Surface Analysis" section beginning on page 9.
SpinRite's makers want you to believe that "weak" sectors are something to be very concerned about, in effect that reputable drive makers design their modern high density drives (ones several generations beyond those using MFM) to regularly rely on these 'defective' sectors to boost capacity, & that only SpinRite's technology will map them out before they cause data loss. This is a dubious idea at best. The techniques used in SpinRite's surface analysis are essentially the same ones modern ATA drives use to monitor for "grown defects" -- except that modern ATA drives contain their own highly capable, purpose-designed proprietary hardware & dedicated operating systems that SpinRite can access only indirectly through clever use of standardized extensions to the ATA command set to do what the drive does anyway.
This is not to say that the product is without merit. It is primarily purposed as a data recovery tool, & for this the extended, low level statistical analysis of the 'raw' analog data from unreliable sectors is a powerful (if not unique to this product) method of data recovery.
There is also some merit to the idea of proactive early detection of unreliable sectors that if used for data storage would eventually require the drive to struggle & perhaps to fail to get 'clean' data from them. (I believe this is what you mean by "zero-ing out defective sectors," just in more technically precise terms.) However, be aware that drives already do this, just with actual data instead of specially designed signals, & in general this is enough to detect sectors that are going bad before the data becomes unrecoverable, at which point the drive moves the data to another sector & maps out the first one to prevent its future use.
In real world terms, these unrecoverable 'hard" errors due to grown defects are very rare in healthy drives, only becoming problematic in drives that are dying, typically because of head crashes, exceeding operating or storage temperature limits, or other traumatic events that affect the magnetic media layer. So something like SpinRite's surface scan is most useful for extending the life of a drive that has already become unreliable or for prescreening drives for gross manufacturing defects. Since the first use makes little economic sense in these days of cheap hard drives & the second use is potentially superfluous because gross defects would likely be quickly detected anyway, users must judge for themselves if using the product for this is worth it.
(The same considerations apply for deciding if or when the frequently seen user advice to 'zero out the drive' as part of preparing it for use accomplishes anything of real worth or not.)
Finally, getting back to the idea of moving the drive to a PC to run SpinRite & why I think it doesn't actually "zero out" defective sectors, I can think of no way it can force the drive to actually map out a sector unless the drive itself determines it should do so. This leaves the alternative of marking the sector in use in the file system's directory structures, which in effect would accomplish the same purpose, but with one important exception: its effectiveness is dependent on the file system remaining in place on the drive. IOW, if a user changed the file system of the volume or changed the partition scheme, the file system metadata marking the sector as in use would be lost, & SpinRite's surface scan would have to be done again after these changes to get it back.
I want to make it clear that I am not certain that this alternative, file system based method of achieving what Spinrite claims it can do is actually how it works, but I can find nothing in the product's documentation that contradicts or conflicts with it, nor am I aware of any standard extension to the ATA command set that would allow SpinRite to directly set the grown defect list. If someone has info that shows I'm wrong, please post it. I have no problem abandoning theories that don't pan out.

UPS Energy Saver on MacBook Pro for External Drives

A search here has shown this topic come up before -- such as at https://discussions.apple.com/message/1886738#1886738 and https://discussions.apple.com/message/8162836#8162836 -- but I can't find a resolution, so I'm bringing it up again.
I have multiple FW drives connected to my MacBook Pro. The MBP is connected to an APC Back-UPS RS 1200. OSX does not make the UPS Energy Saver autoshutdown preferences available on the MBP, the reasoning being that a laptop shouldn't need UPS autoshutdown because it has its own battery which is likely to run for far longer than the UPS would.
That's all well and good for the MBP itself, but it doesn't account for the multiple FW drives which are attached to it for backups and other purposes. In the event of a power outage, without UPS autoshutdown, the UPS will run down, and the drives will abruptly power off, exposing them to potential data loss and damage.
It's also not a solution to suggest that I manually power things down once there's a power outage, because the power can go out while I'm away for more than the few minutes of UPS battery back up time. The only real solution is to have UPS autoshutdown available on all portable machines. Unless and until Apple offers a (surely very simple) OS update to make that happen, I'm still interested in a solution.
APC's own software for autoshutdown stopped being updated long ago, so there is no version compatible with Snow Leopard.
The only potential solution I've found so far is http://www.apcupsd.org/ -- but its documentation is overwhelming and it appears that it may need other supporting software, a fair amount of Terminal usage, etc., all making it not very user-friendly for the very simple usage I'd want to make of it.
Does anyone know of any other solutions, software that can run on a MBP to add UPS autoshutdown functionality?
Re: Apcups, is anyone using it successfully on a MBP? If so, does anyone know if the version listed here -- http://mac.softpedia.com/get/System-Utilities/Apcupsd.shtml -- is a simple application that I can easily install and configure like regular Mac apps? If yes, then I'll likely be very happy with no need for the following question. If no, can anyone provide simple instructions to set up Apcupsd to do what I want?

"You are not doing anything on the computer so no files should be writing to the drives."
Big assumption there. With today's notebooks so capable of acting as desktop substitutes, they are often left running unattended to complete demanding tasks overnight or while the user does other things.
To be able to suspend such activities and gracefully power down an external drive or drives in the event of a power outage, the Mac would have to have instructions from each third-party application or process that is running about how to interrupt its activity safely and without jeopardizing the integrity of whatever hard disk directories are in use. Then it would need to unmount the drive(s) and, if they were bus-powered drives, turn off the power to each of them at the port to which it was connected. I bet it would be possible for all app developers to write such instructions into their apps' code, but where's the incentive for them to do so? This isn't a feature that most users would gladly pay extra for, I suspect, and the cost of adding it to apps that don't have it now and testing it for reliability and proper function under all conceivable circumstances would not be trivial.
If the drive(s) were AC-powered, the computer wouldn't be able to power them down itself -- the UPS would have to do that, or simply leave them on and power them until its battery was depleted or the AC was restored. It wouldn't matter which happened as far as the drives and their contents were concerned, because once the computer stopped using them, powering them off would be safe at any time.

Success: moving bootcamp partition to an external drive

Background
Due to the relatively small, non-exchangable SSD on my Mac, I'd limited the bootcamp partition to 50GB when installing Windows. I needed to install new software in Windows, but was running out of space fast and didn't have the necessary space on the Windows side. I don't use Windows that often and for that reason, I wanted to move the Bootcamp partition to an external hard drive, freeing up space for the Mac side on the internal SSD. I'd read many conflicting reports on the web, some claiming they'd done it successfully, while others said it would be impossible, because Windows 7 wouldn't run from an external drive. I had a HDD in a USB 3 enclosure, and first tried to install Windows to this (using various guides on the web). I was very close to success with this USB 3 drive, but Windows would fail during start-up. Most reports claiming to have successfully been able to run Windows 7 from an external drive, had used Thunderbolt drives, so I decided to get myself a Lacie Rugged USB 3/Thunderbolt series Solid State Drive.
Hardware used
MacBook Pro 15" Retina Display (mid 2012), 2,3 GHz Intel Core i7, 8GB RAM, 250GB SSD
Lacie Rugged USB 3/Thunderbolt series, 120GB Solid State Drive
Software used
Mac OS X Mavericks, 10.9.2
Windows 7 Ultimate
Plus several free downloads from the internet, see description below.
Procedure
Step 1: Get the Thunderbolt drive to work under your Bootcamp Windows 7 installation.
This should be simple enough, but proved to be a little tricky. Here’s what I did (assumes you are running Mac OS X before you begin):
1. Make sure your Thunderbolt drive is disconnected before proceeding.
2. Restart your Mac and hold down the option key (alt key on some keyboards) during startup.
3. Choose the Windows drive to start up Windows 7 on your Bootcamp partition.
4. After log in to Windows 7, download the necessary driver software for your Thunderbolt drive (find it at the manufacturer’s homepage of your Thunderbolt drive - in my case lacie.com).
5. If the downloaded driver installer is in a compressed format (like zip for example) be sure to decompress it before running the driver installer.
6. Shut down your computer.
7. Connect your Thunderbolt drive to your computer.
8. Start up in Windows 7 (see items 2 & 3 above) and if it all went well, you should now be able to see your Thunderbolt drive under Start>Computer.
Step 2: Format your Thunderbolt drive in NTFS-format.
Still running Windows 7 with your Thunderbolt drive connected and visible to the system, it is now time to format your external Thunderbolt drive in NTFS-format. There are several ways of doing this. I used the procedure described here at tedhhack.co.uk.
Step 3: Follow the directions at intowindows.com to clean install Windows 7 onto your external Thunderbolt drive.
As described at intowindows.com, this involves downloading Windows Automated Installation Kit (WAIK) and running command line tools. At step 9 in the described process at intowindows.com, at the point where the installer asks if the drive you are installing to is a USB hard disk, the correct input is Y for yes, even if your external drive is a Thunderbolt drive (and obviously not a USB hard disk).
At step 10 in the described process at intowindows.com (Reboot your PC), remember to hold down the option (or alt) key at every restart in the installation process, so as not to start up in Mac OS X. Also, since your machine now has two Windows 7 installations, Windows Boot Manager will appear and ask you to “Choose an operating system to start” and there is a list of two Windows.
I don’t know how to tell which one is on the external drive and which one is on the internal drive at this point, but I started with the top one on the list and this turned out to be the one I wanted (the newly installed one on the external drive). If you pick the wrong one (on the internal drive) at first, simply restart the computer and choose the other one. You know you got the right one when the installation process continues and asks for further input.
After the Windows installation is complete (there will be at least one other restart required - remember to hold down the option (alt) key to start up in Windows, and choose the same Windows on the list in the Windows Boot Manager), you’ll be running a freshly installed, but crippled Windows 7, as you still haven’t installed the specific drivers for your hardware. But don’t worry, that will be fixed in the next step.
Step 4: Clone your Bootcamp partition from your internal drive to the external Thunderbolt drive.
In this step you will copy all the software, drivers, settings and other files from your Bootcamp partition on your internal drive to your external Thunderbolt drive. The easiest way to do that is to clone your Windows partition - and to that end you’ll need to download some free software: AOMEI Backupper Standard 2.0 fits the bill perfectly, as it will let you clone at the same time as resizing the partition to fit your external Thunderbolt drive (I went from a 50GB internal Bootcamp partition to a 120GB external Thunderbolt SSD).
1. Download AOMEI Backupper Standard 2.0 (I used the 17MB download for Windows 7), install it, and run it.
2. In the left column choose “Clone” and in the right column choose “Partition Clone”. By choosing Partition Clone instead of Disk clone, you won’t ruin the newly created (but invisible) boot partition on the external Thunderbolt drive.
3. Press Next and choose your internal Bootcamp partition as the Source Disk.
4. Press Next again and choose your external Thunderbolt drive (your newly installed Windows 7) as the Destination Disk.
5. Press Next again and you’ll get a warning that you will erase the contents of the destination partition and it asks if this is what you really want to do. Press Yes to this question.
6. Next screen is an Operation Summery. Toward the bottom of the Operation Summery screen there are a few interesting options: Edit Size of Partition, Clone Sector by Sector and Align Partition to Optimize for SSD.
7. If your destination partition is larger than your source destination like mine was, press Edit Size of Partition. This will take you to another screen, where you can drag to resize the partition. I dragged this all the way to the right to give Windows 7 the full size of my external Thunderbolt drive.
8. Leave the checkbox Clone Sector by Sector unchecked.
9. If your external Thunderbolt drive is an SSD, put a check in the checkbox entitled Align Partition to Optimize for SSD.
10. Now press the Start Clone button.
11. When the cloning process is done, exit AOMEI Backupper and restart your computer (holding down the option or alt key) to start up in your new clone of your old Windows 7 with all the same software, drivers, settings and files.
Step 5: Enjoy running all your Windows 7 applications from your external Thunderbolt drive!
Step 6: Here is where I need help/advice – can I remove the Bootcamp partition on my internal drive now?
I am reluctant to entirely remove the Bootcamp partition from my internal drive, as I am unsure whether this will disable me from starting up in Windows. I would love to hear from anyone here with insight on the matter.

Step 6: Here is where I need help/advice – can I remove the Bootcamp partition on my internal drive now?
To answer my own question in Step 6 above, no, or at least I haven't found a way yet...
Here's what I've done so far:
Used the Bootcamp Assistant to remove the bootcamp partition on my internal drive.
Booted the system with the option (alt) key pressed down and now there was NO Windows drive to choose.
Therefore I used the Bootcamp Assistant to install Windows back onto my internal drive (including installing Bootcamp drivers in the Windows environment). This time I chose the minimum partition of 20GB for the Windows installation on the internal drive.
Booted into the new Windows on the internal drive and installed the drivers for my Thunderbolt drive.
Restarted with the option (alt) key pressed down, chose the Windows drive, but Windows Boot Manager still didn't pop up to allow me to choose the Windows installation on the external Thunderbolt drive.
Booted from the Windows DVD and chose Repair.
Restarted with the option (alt) key pressed down, chose the Windows drive, and now Windows Boot Manager finally popped up, which allowed me to choose the Windows installation on the external Thunderbolt drive again, phew!
So, I can run Windows 7 from the external Thunderbolt drive, but I have to use 20GB of my internal drive for a Windows installation I'll never use. Not the best solution, but at least I've saved 30GB of space compared to my previous Bootcamp partition - and I now have enough space to install the Windows 7 software I need on the external Thunderbolt drive...

Extremely Slow Disk Access from External Drives (USB & Firewire)

Following the upgrade to 10.6.2 (from 10.6.1), my computer is communicating extremely slowly with all external drives (both Firewire 400 and USB). File transfers which used to take less than a minute now take 5-10 minutes (less than 1 GB). Peering into the Console, I see messages for each aspect of a file reading: Nov 13 12:30:12 Nautilus /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[152]: Possible unresolved transaction race -105/filename
(Nautilus is the name of the computer)
By "each aspect", I mean that for Pages files, it provides a message for Quicklook,(null) , Contents,(null) , and filename,(null).
All disks are in good health, formatted as FAT32 for ease of use with all OS types, and are SATA.
Again, this occurred immediately following the installation of 10.6.2 (both Software Update and Combo). I've seen similar errors online with iTunes libraries on network drives, but this is on directly connected drives.
I normally wouldn't ask this, but, is there a way to reinstall 10.6.1 over .2? At this point, Time Machine would likely cause me to lose other data as well in a full revert, since it has been more than a few days.

I have various personal files backed up on these drives (not system data): music, pictures, documents, etc.
FAT32 should not be an issue, as I have used these drives for over 2 years with Tiger, Leopard, and then Snow Leopard with nay an issue, until now. Additionally, while the Time Machine backup may be an archive, it is the sole occupier of an HFS-formatted partition which is not exhibiting the issue. I only included that information since it is physically on the same drive as a partition (FAT32) which is being troublesome to rule out driver/hardware problems.
Bottom line: All of my drives worked perfectly on 10.6.1 (and continue to do so on my other Macs (10.5.8), but do not on 10.6.2. I was only looking for a potential solution to my computer's specific issue, not a statement that my "compromise" is the cause of my problems.
Actually, since Apple fully supports read/write access on FAT32 partitions, I should, indeed, be able to "have all things all ways...", no offense intended.

How do I stop Finder from crashing when I try to view my external drive?

Hello,
I've read through a few similar posts, but the solutions don't seem to fit my problem. I was moving some files around on an external drive that I've been using for a year with no problems. While moving one file to another folder (within the drive, not between my computer and the drive), it froze up. After waiting for 20 minutes or so, I pulled the drive out and restarted the computer.
Now when I plug the drive back in, it shows up as usual, but when I click on it, Finder crashes immediately. I ran disk utility repair, and it says "The volume appears to be ok" in green, but it still crashes finder when I try to open it. Based on the advice of another post, I ran Console, and copied what I thought to be the relevant portion of the transcript, though I don't know what any of it means ("Uzak" is the name of the drive):

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything suggested in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The procedure will help identify which such modifications you've installed, as well as some other aspects of the configuration that may be related to the problem.
Don’t be alarmed by the seeming complexity of these instructions — they’re easy to carry out. Here's a brief summary: In each of two steps, you copy a line of text from this web page into a window in another application. You wait about a minute. Then you paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is copy; paste; paste again. That's all there is to it. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken while booted in “normal” mode. If the system is now running in safe mode and is bootable in normal mode, reboot as usual. If it only boots in safe mode, use that.
Below are instructions to enter UNIX shell commands. They do nothing but produce human-readable output. However, you need to think carefully before running any program at the behest of a stranger on a public message board. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. If you can't satisfy yourself that these instructions are safe, don't follow them.
The commands will line-wrap or scroll in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it.
If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. Step 1 should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
PB=/usr/libexec/PlistBuddy; PR () { [[ "$o" ]] && printf '\n%s:\n\n%s\n' "$1" "$o"; }; PC () { o=$(grep [^[:blank:]] "$2"); PR "$1"; }; PF () { o=$($PB -c Print "$2" | awk -F'= ' \/$3'/{print $2}'); PR "$1"; }; PN () { [[ $o -eq 0 ]] || printf "\n%s: %s\n" "$1" $o; }; { system_profiler SPSoftwareDataType | sed '8!d;s/^ *//'; o=$(system_profiler SPDiagnosticsDataType | sed '5,6!d'); fgrep -q P <<< "$o" && o=; PR "POST"; o=$(( $(vm_stat | awk '/Pageo/{sub("\\.",""); print $2}')/256 )); [[ $o -gt 1024 ]] && printf "\nPageouts: %s MiB\n" $o; s=( $(sar -u 1 10 | sed '$!d') ); [[ ${s[4]} -lt 90 ]] && o=$( printf 'User %s%%\t\tSystem %s%%' ${s[1]} ${s[3]} ) || o=; PR "Total CPU usage"; [[ "$o" ]] && o=$(ps acrx -o comm=Process,ruid=User,%cpu | sed 's/ */:/g' | head -6 | awk -F: '{ printf "%-10s\t%s\t%s\n", $1, $2, $3 }'); PR "CPU usage by process"; o=$(kextstat -kl | grep -v com\\.apple | cut -c53- | cut -d\< -f1); PR "Loaded extrinsic kernel extensions"; o=$(launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)|\.[0-9]+$/{print $3}'); PR "Loaded extrinsic user agents"; o=$(launchctl getenv DYLD_INSERT_LIBRARIES); PR "Inserted libraries"; PC "cron configuration" /e*/cron*; o=$(crontab -l | grep [^[:blank:]]); PR "User cron tasks"; PC "Global launchd configuration" /e*/lau*; PC "Per-user launchd configuration" ~/.lau*; PF "Global login items" /L*/P*/loginw* Path; PF "Per-user login items" L*/P*/*loginit* Name; PF "Safari extensions" L*/Saf*/*/E*.plist Bundle | sed 's/\..*$//;s/-[1-9]$//'; o=$(find ~ $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 $ | wc -l); PN "Restricted user files"; cd; o=$(find -L /S*/L*/E* {,/}L*/{A*d,Compon,Ex,In,Keyb,Mail/Bu,P*P,Qu,Scripti,Servi,Spo}* -type d -name Contents -prune | while read d; do ID=$($PB -c 'Print :CFBundleIdentifier' "$d/Info.plist") || ID=; ID=${ID:-No bundle ID}; egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|microsoft\.MDI|print|SoftRAID" <<< $ID && printf '%s\n\t(%s)\n' "${d%/Contents}" "$ID"; done); PR "Extrinsic loadable bundles"; o=$(find /u*/{,*/}lib -type f -exec sh -c 'file -b "$1" | grep -qw shared && ! codesign -v "$1"' {} {} \; -print); PR "Unsigned shared libraries"; o=$(system_profiler SPFontsDataType | egrep "Valid: N|Duplicate: Y" | wc -l); PN "Font problems"; for d in {,/}L*/{La,Priv,Sta}*; do o=$(ls -A "$d"); PR "$d"; done; } 2> /dev/null | pbcopy; echo $'\nStep 1 done'
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "Step 1 done" to appear below what you entered. The output of the command will beautomatically copied to the Clipboard. All you have to do is paste into a reply to this message by pressing command-Vagain. Please don't copy anything from the Terminal window. No typing is involved in this step.
Step 2
Remember that you must be logged in as an administrator for this step. Do as in Step 1 with this line:
PR () { [[ "$o" ]] && printf '\n%s:\n\n%s\n' "$1" "$o"; }; { o=$(sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|calendarse|cups|dove|isc|ntp|post[fg]|x)/{print $3}'); PR "Loaded extrinsic daemons"; o=$(sudo defaults read com.apple.loginwindow LoginHook); PR "Login hook"; o=$(sudo crontab -l | grep [^[:blank:]]); PR "Root cron tasks"; o=$(syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail -n25 | awk '/:/{$4=""; print}'); PR "Log check"; } 2>&- | pbcopy; echo $'\nStep 2 done'
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
You can then quit Terminal. Please note:
☞ Steps 1 and 2 are all copy-and-paste — type only your login password when prompted.
☞ When you type your password, you won't see what you're typing.
☞ If you don’t have a password, set one before taking Step 2. If that’s not possible, skip the step.
☞ Step 2 might not produce any output, in which case the Clipboard will be empty. Step 1 will always produce something.
☞ The commands don't change anything, and merely running them will do neither good nor harm.
☞ Remember to post the output. It's already in the Clipboard. You don't have to copy it. Just paste into a reply
☞ If any personal information, such as your name or email address, appears in the output of either command, anonymize it before posting. Usually that won't be necessary.
☞ Don't post the contents of the Terminal window.
☞ Don't paste the output of Step 1 into the Terminal window. Paste it into a reply.

Sharing Itunes library and backup on external drive

Would appreciate if anyone can offer help on their experiences of external / NAS drives. I've been looking for the best solution to move my entire Itunes library to an external drive that I can put on the network so can have access from PC's, Mac and Iphone. Just recently moved to new MBP but still have PC's in home.
Have looked at varying solutions and think I've got it narrowed down to going for either QNAP TS212 NAS or dedicated Iomega Network hard drive but seem to come over a lot of conflicting reports of these items not working well with MAC, particularily some comments on the use of Iomega which is the more cost effective solution.
A little background was planning on 2TB drives and partioning for Itunes library, Time Machine backups and PC backups. Have the S/W on MAC to read/write NTFS.
From my research the dedicated NAS would be appear to be the best answer but a lot more expensive than a network drive.
Can anyone advise of a network drive that they have experienced working well for this type of configuration?
Also is there any issues with syncing Iphone to an external networked library?
Any Advice Appreciated
Thanks

when looked in preferences the old location was still there, eventually changed in preferences
Trev,
changing iTunes media folder location via preferences > advanced tells iTunes where to put new additions to your library, not where the current content is.
also, with your library now on the NAS, you must make sure the NAS is mounted on your desktop before launching iTunes.
... still showed an issue with the file locations and the exclamation marks.
you may have done something wrong initially (during re-locating your library to the NAS) because the exclamation marks usually appear when media files were moved using the finder and iTunes lost track of their location.
you might be able to use this script:
iTunes Track CPR v1.3
This script attempts to locate the files of so-called "dead tracks"--iTunes tracks designated with (!)--that you assume are not actually missing but are still located in the iTunes Music folder in their "iTunes File Order" (Music -> Artist -> Album -> file.xxx)."

How do i manage 1 iphoto library on 2 external drives?

I'm trying to find the most efficient way to manage 1 iphoto library across 2 external drives. In case one of my external drives dies, I'll have a backup.
I know how to copy my iphoto library onto another drive, but my question is how to manage the 2 drives when i add photos/videos to them from my iphone.
Currently, I import photos/vids from iphone onto 1 drive. Then unmount the external drive and hook up another drive. I direct iphoto to use the new drive as it's library and then import the photos/vids again onto the second drive. I make sure the event is named the same, so I have the same iphoto setup across both drives. Then i delete the photos/vids from my iphone.
Is there a more efficient way to do this? Or software that can do this in one step?
Thanks in advance for any help!

You want to have a backup of your working library on your MacBook Pro on each of two external HDs, correct?
If yes then use a backup application like Synk or Synk Pro that can incrementally backup the library, i.e. copy only those new of modified files. If you go to MacUpdate.com and do a search for "backup" you'll get a list of potential candidates.
Then all you need to do is connect EHD#1 and run the backup app to update the library then connect EHD#2 and do the same. It only takes several seconds to make the incremental backup. Synk Pro can be configured to automically start the backup when the external drives are connected. I'm not sure but believe some of the other backup apps could do the same.

External Drive No Longer Accessible after 10.9.5 Update

After upgrading to 10.9.5 from 10.9.4, I have lost access to my external drive (USB connected) used by Time Machine. The icon on the desktop is amber. Disk Utility can not repair it. I get "Error Some information was unavailable during an internal lookup." Also.. "Problems were encountered during repair of the partition map." The disk format is Mac OS Extended (Journaled). If I launch Windows 7 (using Fusion 6) on the iMac, it recognizes the drive (I have the HFS+ driver installed.) I can read and write to the drive and see all the time machine backups on the Win 7 virtual machine. I am logged in to my iMac as a Standard User. Logging in as the Administrator has no effect. The drive can not be repaired or formatted. This is a late 2009 iMac with 12GB ram. Original OS was Snow Leopard. It was upgraded from 10.6.8 to the full Mavericks OS.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Trying to create HD disk image on external drive

I'm trying to use the disc utility to create a disk image of my HD, saved to an external drive (500 GB, My Book) via FireWire. After choosing the appropriate origin and destination info on the drop-down menus, and clicking Save, I get a dialogue box that for an instant shows the operation in progress, then reverts to: Unable to save DMG, resources busy. I might not have the exact words, but it's very close.
What am I doing wrong? What resource is "busy", the HD or the external? The dialogue box doesn't indicate that info. I'm not aware of any obvious conflicts. No other applications are running.

Were you trying to copy the Mac OS volume?
I think the OS itself is a big program that is running. So somehow the source is changing every minuets. You may try SuperDuper! or Carbon copy cloner to do what you want, both of which are free, at least some of the main functions are. They should have no problem when dealing with the OS that is currently running.

Can't find iTunes Library on external drive after iTunes 8 install

My music library (50GB) has always been on an external drive. After installing iTunes 8 I went to preferences to change from default to this drive but nothing showed up. The complete library is still on the disk. Tried reinstalling V 7 but still no luck.
Any ideas how to "reconnect" the library ?
iPOD is also still complete. Is there a reverse recovery that my iPOD content could be retrieved to my external drive as the library ?
Message was edited by: samben52

Changing the Library location within iTunes instructs the program were to store future music when Importing - not where to go look for current music.
You music files may be on the ExHD, but your music metadata (Playlists, Playcounts, Ratings, and other potential important attributes) are kept in the Library Database file. See: What are the iTunes Library files?
If you did not save a copy of this file, you may be in for a long recovery.
This well-written iLounge Article is a must-read for anyone who wants/needs a better understanding of how iTunes manages your music. It may shed some light on what you need to do next. or at the very least, help you describe your specific problem here a bit better.

Best of Luck
