Slow read times from external drive (10KB/s)

Hi all,
I have a nice external setup that includes two WD 500GB drives linked up with firewire. I usually copy stuff I want to keep into drive A and then use rsync to sync between the two disks (A and B). Today I've copied some new files into drive A and then used rsync to sync into drive B. Some of the files were copied at normal rate, but to my surprise most of the files were copied extremely slow - about 10KB/s!!! (all the files are at the same size). I did managed to read all the files, but very slowly.
So to take rsync out of the equation I've tried to copy the files manually via finder, and it was also extremely slow.
I've also verified the following:
* Reading same files from drive B - fast as normal.
* connecting drive A by USB - still slow
* disk utility repair and verify - all are OK
The disk is not clicking or making funny noises.
I am not sure what could be the problem, maybe it has to do with the file system? Any idea what could it be?
Thanks!

Try using Disk Utility to repair the disk. Note that I am not referring to the repair disk permissions button on the left. I am referring to the repair disk button on the right of the Disk Utility window.

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.

External Drive with Time Machine, booting from external drive with utilitie

I'm using Time Machine now with
a LaCie 1TB external hard drive.
Everything works fine.
But, I've been wondering:
Can I place a program like TechTool
on the external drive (that Time Machine uses)
and boot from that external drive.
I would like to be able to do that,
because diagnostics and repair programs
only works properly and fully when they run from
external drives. Anything on the internal drive can be repaired
and examine. Impossible to do if Techtool is on the same
drive that's been examined.
Any thoughts as to what I should do?
Thanks
iMac, Leopard, Time Machine, Lacie Quadra 1TB drive.
P.S. Stupid question: If my computer crashes, and I reboot from Time Machine
(from the external drive) how does the computer know which backup to take ?!?
Isn't there many versions of the OS on the Time Machine backup taken at different times?

As V.K. says, you can't boot from TM backups.
But you can restore your entire system from any one of them, per the procedure in #14 of the Frequently Asked Questions *User Tip,* also at the top of this forum.
You can also selectively restore from them, while running normally. See #15 in the FAQ Tip.

How do I restore the entire system from a Time Machine external drive?

Hello everyone,
Up front - I have searched through numerous threads but have not yet been able to solve my problem - even though it is presumably easy for many.
So... I had to bring in my late 2009 27" iMac to Apple to replace the hard drive - mine was one of the thousands affected by the defective Seagate 1 TB disk recall. I was told that the disk would be cloned, but nevertheless I made a full system backup with Time Machine to a dedicated external hard drive.
A week later and I now have my iMac back - but when I boot, I only see a white screen with a pointer, so it appears that the drive was not cloned - but that I now have a blank 1 TB disk, correct?
I have also tried booting with the external drive attached, thinking that the dedicated Time Machine external drive would allow me to boot directly from it and restore the system if need be - I booted with CMD+R, tried again with ALT ... no luck.
And I cannot find my Mac OS DVDs...
So... is the drive blank, or am I missing something here?
If so, how can I boot from the external Time Machine drive, or is that not possible either?
Any pointers greatly appreciated, thanks very much in advance.

Call Apple to get replacement DVDs > http://support.apple.com/kb/HE57
1. Insert the Mac OS X DVD and press C key while your computer is starting.
2. Go to Utilities menu and restore the backup.
You should have made a clone instead of the backup because Apple gives the hard disk without OS X

Can't read iPhoto library from external drive

I suddenly can't can't read iPhoto library from external drive. I have talked to WD and nohing is wrong with the network drive. I can open images and files from it. But, I can't read in iPhoto Library.

Network Drive? a NAS?
iPhoto needs to have the Library sitting on disk formatted Mac OS Extended (Journaled). Users with the Library sitting on disks otherwise formatted regularly report issues including, but not limited to, importing, exporting, saving edits and sharing the photos.
Basically, you need to move the library to a correctly formatted disk.

Hello
I bought my wife a new MacBook Pro, in setting it up for her, I took her Time Machine external drive to migrate onto the new machine but her old MBP not only was on 10.6, it was my old machine which I was still Administrator for.
i plugged in the external drive to start the migration process after entering her name and username from the old machine which gave me the options on transferring the old data over.
I also unchecked the Administrative end that had my info hoping that ONLY her data, files, etc., would be the ones sent over to her new machine which I wanted her to be the ONLY Administrator for. All went like clockwork until the restart.
Normally the screen should show the username and only need the password but both entries were blank, as in ‘Other’ sign in option available only. I entered her name and password, nothing….used her username and password, nothing. Used my old Administrator name and password, NOTHING!
I tried defaulting to factory settings from the Restore feature but it directs me to notify Apple. I tried in Terminal to change the password, nothing. I tried to boot from MY external drive and it doesn’t recognize it. I tried to even use my external drive which actually has the Mavericks upgrade, nothing!
Basically I can only get the startup screen which isn’t accepting the username/password or the Restore feature which doesn’t offer any options helpful!
Please, how do I start from scratch and start over here? Or simply change the Administrator name and password so I can proceed with everything thats already on there? I wish I could even boot from another drive but no luck on anything!

First, on the old machine, make your wife's account an admin one. Log into it and delete yours. Then, update the TM backup. Finally, use Internet recovery mode, ⌘⌥R, erase the HD, and restore the OS. One first boot, follow the steps outlined in Pondini's Setup New Mac guide.

Why do you feel you need to do this? That is such a 'Windows thing' to do!
And secondly does RAM memory cards go bad
Very rarely, but nothing in life is guaranteed (except death and taxes)! If you purchased RAM from a reputable source like Crucial or OWC it will carry a lifetime warranty.

It's confirmed, H.e.l.l. has finally frozen over! TM drives are now bootable!
Still it's not a real bootable clone, can't run the computer off the external drive for long in only Recovery mode, still requires the boot drive to be replaced if it not functional, and with TM backing up every hour, isn't going to offer much software protection as the TM drive is just as likely to be as messed up as the internal boot drive.
For a iMac it still requires the computer to be taken in to Apple for a drive replacement, as ONLY Apple can do it due to proprietary connections and firmware on the iMac hard drives.
But it is bootable!
The backup time factor can be controlled using TimeMachine Editor, from every hour to just when the user thinks it's necessary.
Apple lurches slightly forward! Hurray!
Question is, can one restore from earlier stable TM's or just the last one? In this bootable fashion?

Broken in Logic 9?: Reindex loops from external drive

Adding loops from an external drive in Logic 9 does not seem to work any longer. It used to work great in L8. Anyone have similar experiences? Know any work arounds? Is it a bug? If it's a bug I'll file it with Apple.
Previously in Logic 8 it was easy to reindex loops on an external drive:
(1) Delete the loop indexes from root/Library/Audio/Apple Loops Index
(2) Use Finder to locate the loops on the external
(3) Drag the loop folders into the L8 media browser.
(4) L8 asks if you want to copy the loops or use them from their present location. Select present location intsead of copy locally.
(5) L8 takes 5-20 minutes to build index of loops from external drive
I have tried this procedure several times in L9 without success. Instead I get the following:
(1) Delete the loop indexes from root/Library/Audio/Apple Loops
(2) Use Finder to locate the loops on the external
(3) Drag the loop folders into the L8 media browser.
(4) L9 ask for my admin password.
(5) Enter my password
(6) I'm NOT asked if I want to copy loops locally or use them in their present location. Instead a reindex progress dialog comes up for 2 seconds then goes away.
(7) In the end nothing happened. No loops copied, indexed, or anything
There is only one way I managed to get loops into L9 but it is exactly what I'm NOT looking for:
(1) In the folder with all my loops spotlight search ".CAF" (In this case want to reindex Apple content which is all CAF)
(2) Make sure to click "show more" at the bottom of the search results.
(3) Drag the search results to the loop browser.
(4) L9 indexes them all right, AND also copies them to my user library! All 30 GBs worth. Definitely not what I want.
In the end, I had to reinstall the Loops from the DVDs and specify an external location for them. (This whole mess got started when I tried to move the GarageBand and iLife loops to an external drive. The installer does not let you specify a location for them.)
Just so you know I've done some homework:
I've scoured other Logic forums and found these relevant threads that in the end did not solve the issue. They mostly seem to refer to Logic 8 which does not have this issue.

Thread 1
@ Logic Pro Help

Thread 2
Thread 3 this fellow seems to have a similar problem as I. He drags folders into the loop browser but nothing happens.
@ Apple Discussions

Thread 2

I just installed LP9 and all my loops and samples are on external drives. The drag and drop onto the browser method worked fine and I WAS given the option to move the files or not. The only exception to the above is Ultrabeat samples. They seem to want to be on the System drive.

Since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists

since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists?

My own opinion is that you should install the later appropriate version of Silverkeeper. That said, I would in fact recommend if you can wait a few days for an answer, that you email the La Cie Silverkeeper backup team via the email link on the site at http://www.lacie.com/silverkeeper/
They are careful to say they are not officially providing a backup service, but when I emailed them with a query regarding usage about a year ago after downloading Silverkeeper for myself, I got a reply within a couple of days that cleared up my question.

Problems booting from external drives

Ever since I got this 6-core 2013 MacPro (January 2015), I have had strange problems and glitches, but for this posting, I am talking about problems being able to boot up from external drives. I took the 4 external drives out of my old 2009 MacPro and put them into a 4-bay Thunderbolt enclosure. This enclosure can be configured as a RAID if all drives are the same (which they are not) or it can just be a place to be able to access all 4 drives. I used to be able to boot from each of those drives on the older MacPro but I am unable to do so now. They show up in the System Preferences/Startup Disk but if I choose one, it just reboots into the new MacPro drive. I even tried pulling out a couple of the drives and mounting each into a USB 3.0 (Sabrent) dock and still I could not boot from those drives which have the latest version of Yosemite. Yes, they are formatted correctly. I used to boot from them. I was able to clone one of the drives to a Seagate USB 3.0 hard drive and boot from that. Although, the clone was not perfect. It didn't transfer all my settings so I could recover some logins and serial numbers I wanted that I have never been able to retrieve since I got this new Mac.
Yesterday, I formatted a 32GB flash drive and tried to install Yosemite on it. I planned to put DiskWarrior on it. When I started to install Yosemite (from a saved download) it let me choose that drive, but when it restarted before installing, I was right back where I started on my MacPro's hard drive.
Is this normal behavior for the 2013 MacPro? Or is it just mine? I am beginning to think I may have a lemon since I have had other strange problems that don't go away.

Not all external devices are bootable. First stop would be involve whoever handles the 4-bay Thunderbolt. Seeing how it has a bridge most likely in order to support RAID mode that may not have the correct frmware or other reasons.

Maybe. What kind of other computer are you talking about? What operating system is it running? What kind of wireless router are you using?
Your best bet may be to just reset the router and set it up again.
Just so you know, WEP is a very old security system for wireless and is considered insecure. If you have it available, use WPA2.

Best method of importing from external drive?

I have a 1T LaCie and want to know the best method to get those images into LR. The defaults are: "Add" and "NewPhotos" to "MyCatalog"
I think I may have more than one catalog and am not certain how to combine them. Is it best practice to have only one catalog?

Can Disk Utility get SMART status from external drives?

I recently updated my backup plan with a NewerTech quad-interface dock and a WD Caviar Green hd. I'm using the FW800 interface to connect to my iMac (10.6.7) Everything works perfectly, as expected. I noticed, though, that Disk Utility cannot report the SMART status on the new WD drive. DU simply says "Not Supported" under SMART Status.
Is Disk Utility telling me that it doesn't read SMART status from external drives? Or is it telling me that the new drive doesn't support SMART (which I would find highly unusual)? And, if it's Disk Utility that can't read the status, are there any third-party apps that can report the SMART status on an external drive?
Thanks,
JimC

Unfortunately I cannot speak to the NewerTech enclosure, but in principle it appears to be possible to have SMART information displayed even for external drives if the enclosure's bridge controller chip allows it.
My experience:
I've used two MacPower Pleiades FW800/400/USB/eSATA enclosures for several years and I've now supplemented them with two additional inXtron enclosures. They all work as expected daisy-chained to the iMac.
The interesting thing is that the inXtron enclosures came with a CD with some software on it ("Smart AP") which is not available for download, notably a Dashboard Widget for displaying actual and maximum temperatures, total hours of operation, start/stop cycles, drive model and serial number.
This widget is complete garbage, though – it is a nauseating nightmare of extreme over-design at the expense of even basic usability:
http://www.inxtron.com/information-center/smart-ap-for-external-hard-drives
To make matters even worse, it can only display the above information for the first external drive connected.
BUT: This Widget internally calls a command line utility which does the actual parameter retrieval, and that one can be called from the terminal as well.
So after installing the software from CD and effectively discarding the Widget, I checked out the command line utility in the Terminal and found that this utility actually reported data about ALL my enclosures, both the inXtron and the MacPower ones (there seems to be firmware compatibility across these):
(The '$' is supposed to be Terminal's bash prompt – type in only the rest of the respective line.)
$ /Applications/MacpowerAP/GetSMART 1
29 50 13 8
53 67 645 15829
52 53 90 7105
51 52 18 13
Each line reports the following for one connected enclosure:
[temp] [maxtemp] [cycles] [hours]
The drives are reported first USB, then FireWire drives, each in the order of first connection / mounting.

This might report the firmware revision or something like that.
These are the commands I know about, and they apply only to the "Smart AP" software supplied with current inXtron enclosures, but it may be possible that other brands use it as well.
I have not been able to identify information about the self-test (early(?) failure warning), but it might be contained as well in the data reported above.
As always, your mileage may vary and you should never do such experiments without FIRST making sure you've got backups of your data and that such backup is not connected during experimentation!
Maybe this can help some people getting the information they need; And maybe there are similar capabilities with other enclosures. At the very least it demonstrates that with the proper firmware in the enclosures themselves and some software on the Mac it IS possible to get at least some of the SMART information from the drive in an external FireWire- or USB-connected enclosure.
None of that is fed into the system's "official" SMART mechanism, though, so no luck using standard mechanisms or applications for it. It's strictly a command-line affair (deservedly disregarding the mishappen Widget).
Good luck!

Why won't photos from external drive stay on my computer (iPhoto) once I disconnect the external drive?

I'm trying to move photos from my external drive to my new computer. When I connect the external drive, I'm able to view all the photos in iPhoto, and I'm able to drag photos to a desktop folder and/or directly into iPhoto. But, when I disconnect the external drive, I no longer have access to the photos on my computer. I'm sure there's a step I may be overlooking but I'm using the same process I've used in the past and cannot determine next steps.

Thanks so far.
I'm currently working on a 2012 MacBook Air 13", running OSX 10.8.
Upon opening my external drive, I've dragged the iPhoto Library to my computer's desktop. When I've opened iPhoto and tried to import the library (from external drive and/or from the desktop), I'm unable to do so, i.e., the library is not highlighted (it won't allow me to click on it).
I can open and view the library from my external drive in iPhoto when the external drive is connected to the computer. But, once the external drive is disconnected from the computer, I'm unable to view the library
I've tried all of the aforementioned when the "Copy Imported Item(s) to the iPhoto Library" is checked.
