Second External Drive Keeps Dropping Off
I have two external G-Drives daisy chained together via firewire 800 and each have their own power plug. They show up on finder as Drive A and Drive B.
They normally spin down when not accessed and spin up as needed. It appears that when I wake up the Mac from sleep mode, Drive B
is dropped off and Drive A is still on finder.
The only way to get drive B to show up again is to power it off then back on. Is there anyway to correct this?
Primary reason for electromagnetic devices to fail is the power surge at
start up and the resultant warming up to a satisfactory operating
temperature. Akin to light bulbs failing on startup, but not when
constantly burning.
Hmm, I've heard that one before, but I'm skeptical. And not sure the light bulg analogy is really suitable. Even shut down, if still connected to power, there's trickle current going to the hardware, if I'm not mistaken. Anyway, there are posts from people who've shut down at night for ten years straight who've had no problems and then from users like you who swear by the opposite. A lot of this is just too anecdotal. I still need to see convincing statistics; and I don't think there are any.
And even if you're right about the startup power surge and temperature jolt to the drive, you'd still have to weigh in the possible negative of too much heat, too much of a good thing by never allowing it to sleep. Must also depend on ambient room temp. It was just 103 here (90+ inside) and I don't think I would have been helping the hardware last by not allowing the computer to sleep under those conditions.
Apple's recommendation to only shut down if the computer won't be used for a length of time and sleep otherwise is based more on the convenience factor. There's nothing in there about what's better for hardware.
Anyway, different strokes etc. Not something that will ever be settled definitively one way or the other. Probably a lot depends on the luck of the draw.
Btw, Seagate's are getting a reputation lately for being pretty crappy.

Using a Second External Drive For Time Machine Backup
I have been using Time Machine for almost a year and the external drive I'm using is almost full. Can I switch to a second external drive? If I decide to keep using the same drive is there a way to keep my original backup? Is there information that I need from that first backup that I did?
Thank you!!!bvasel900 wrote:
Hi, and welcome to the forums.

Yes, if that's what you want to do (see below). If you start "fresh" on a new drive, your first backup will be a full one; everything on your system. Or, you can copy your current backups to it via the procedure in item #18 of the Frequently Asked Questions *User Tip* at the top of this forum. TM will then continue making it's usual "incremental" backups, and you can erase the old disk and use it for other things.
If I decide to keep using the same drive is there a way to keep my original backup? Is there information that I need from that first backup that I did?
Probably not. As Mr. Peck noted, TM will automatically delete your oldest backups when it needs room for new ones (unless you have the +*Warn when old backups are deleted+* box checked in TM Preferences > Options).
But unless you've been deleting things from your internal HD, counting on TM to keep it's backup copies indefinitely, you won't lose anything you need.
That's because of the "magic" of Time Machine. Each backup is an "incremental" backup, copying only the items that have been added or changed since the last backup. But by using "multi-links" to the backups of items that did not change, each backup is, in effect, a full, complete copy of your entire system!
So when TM deletes your oldest backup, all it will be deleting are it's copies of things you changed or deleted long ago. -
Hi everyone
I wonder if anyone can offer me some advice to rectify the problems I'm experiencing in my itunes?
I have been saving my media to an external hard drive since rebuilding my itunes collection, while keeping the library on the hard drive of my MBP. This was working well with no problems but as my media reached 300GB on my external I thought I would copy it to another external hard drive as back up, and after that I decided to also make a copy of my library data to the same second external drive so I would have a full back up of itunes in case of failure of my main hard drive...
So after copying my media from my first external drive to the second, and then copying the library data from my MBP hard drive it seems the copy of my media and the copied library are working fine on my second external hard drive, but now when I open the first external drive where I originally was saving my media files I am suffering quite a lot of broken links???...I followed the copy process as I have done in the past although I did not tick the check box for renaming and moving my media as it was about to be copied,and I thought that was correct as I used the consolidate function to copy it..
Been trying to figure out how to rectify the problem tonight and am getting nowhere fast. Can anyone offer suggestions as to how I can sort the issue on my original external hard drive as it's the one I prefer to store my media on and it was functioning perfectly before?? from having a tidy and clearly functioning itunes I now have a mass of problems....
I hope this is clear to someone.....as I was hoping to have it fixed in readiness for a new MBP...am I missing something obvious?OK, this should sort you out...
Move the following files and folders from /Volumes/Backup/iTunes up to /Volumes/Backup/
Album Artwork (folder)
iTunes Library.itl
iTunes Library Extras.itdb
iTunes Library Genius.itdb
iTunes Library.xml
sentinel (hidden)
Launch iTunes. It should warn that the library is missing. Browse to the file /Volumes/Backup/iTunes Library.itl and open it.
Go to iTunes > Preferences > Advanced and change the media folder location to /Volumes/Backup/Music. Let iTunes consolidate files if it asks, if not use File > Library > Organize Library... Tick Consolidate files and click OK.
Close iTunes. Rename /Volumes/Backup/Music as /Volumes/Backup/iTunes Media. Start iTunes.
Go to iTunes > Preferences > Advanced, check that the media folder location now reads /Volumes/Backup/iTunes Media. If necessary, change and then close and reopen iTunes.
Go to File > Library Organize Library... and, if not greyed out, tick Rearrange files in the folder iTunes Media, then click OK.
Delete /Volumes/Backup/iTunes/iTunes Media which now contains redundant copies.
Move the following files and folders from /Volumes/Backup/ into /Volumes/Backup/iTunes
Album Artwork (folder)
iTunes Media (folder)
iTunes Library.itl
iTunes Library Extras.itdb
iTunes Library Genius.itdb
iTunes Library.xml
sentinel (hidden)
Launch iTunes. It should warn that the library is missing. Browse to the file /Volumes/Backup/iTunes/iTunes Library.itl and open it.
Go to iTunes > Preferences > Advanced, check that the media folder location now reads /Volumes/Backup/iTunes/iTunes Media. If necessary, change and then close and reopen iTunes.
Each time you change something and start iTunes just check that a track will play. If not, close iTunes and undo your last action.
That should be it. You can clone this iTunes folder to any other drive and the clone is a functioning copy of your library.

hi Robert,
thanks a lot for your reply.
here is the uplink port profile config:
port-profile type ethernet HostUplink
vmware port-group
switchport mode trunk
switchport trunk native vlan 1
switchport trunk allowed vlan 1-3967,4048-4093
channel-group auto mode on mac-pinning
no shutdown
system vlan 803,832,900-901
state enabled
803 is mgmt for both esx and vsm, 900 is control, 901 is packet.
my NC553i driver version is different from what you suggested, it is 2.102.518.0, any reason why you suggest to use the version you specified?
I have been trying to contact HP support, to be honest, not saying overall, but from my experience, they are much less helpful then Cisco support, I will keep trying.
thanks

Why does my generation 1 ipad keep dropping off
Why does my ipad keep dropping off. It is generation 1.
Dropping of of what - wifi? When you ask a question you need to provide enough info to get an answer.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
• Launch Settings app
• Tap on Wi-Fi
• Tap on the blue arrow of the Wi-Fi network that you connect to from the list
• In the window that opens, tap on the Renew Lease button

Since I have downloaded IOS5 on my IPAD2 and synced to my IMac, Safari keeps dropping off before site is downloaded and is slow. There was an icon that showed how many windows were open on Safari and when pressed displayed them, that has disappeared and apps do not always download. Sometimes by making several/many attempts, it eventually downloads the website or app, but this is not right. When trying to dowload any lonks from an email, they simply do not open, it keeps going back to the home screen. Does anybody have any suggestions? I only bought the IPAD 2 in June!
Also the touch screen does not seem to be responding adequately. Thank you for any help you can give.

HT1338 wifi connection keeps dropping off on macbook pro
hi, i just bought a Macbook Pro 13" and find that the wifi connection on my Macbook keeps dropping off every few minutes. i have tried numerous measures suggested that i could find on the net but the problem still persists. i don't know if it has anything to do with the Norton Internet Security that i installed on the laptop. pls help. thanks.

I seem to kill HD's every two years...the last two i've installed were WD Caviar Black 1TB 7200rpm 3.5" drives. The speed gains over stock drives have been remarkable. I don't blame the drives for the failures, my machines are up and running 16 hours a day, every day, year round. They die from 'mileage' so to speak...i assume...there's no viral acvtivity or questionable downloads to gunk things up...just lots of work.
I have my third new drive ready to install in my intel based iMac...but i've had a thought...I want to install a SSD in my iMac for the speed gain (and recent price drops)...for standard storage i want to use this new WD Caviar Black 1TB in an external drive bay and connect via firewire 800 for storing everything except the OS and my most commonly used software...am i crazy? will the firewire 800 external drive negate the speed gained with an internal SSD??
I have four iMacs in my office, and one at home. I buy second hand and install new drives and boost memory. I'm going to do this on my 'home' machine...if it works out well i want to upgrade the other three this way...but first i need to know if i'm just dreaming, or will it really make a difference? or even possible??
Thanks!
2.66 intell core2duo
2009 iMac
8gig ram
1 gig hd
OSX ver. 10.8The SSD gives great bootup and Application launch speed. I think it also speeds up the video rendering a bit, I do all that on the SSD and then move the finished project to the external drives. As far as the speed for the external drives they are quick enough for viewing video and the file transfer rate is good. I had initially put the SSD into an external cradle (FW800) and the system was faster than on the internal drive. I only got a 1.5GBs SATA drive, perhaps yours could benefit from the 3GBs. I know the 6GBs would be too fast and costs a lot more, even the MacPros need special hookups to make use of the 6GBs.

External HDD keeps dropping out (without ejecting itself) ~ due to 1 bad partition
Hi,
As stated above, my faithful WD 1TB MyPassport HDD keeps dropping out by itself, ie. icon disappears from my desktop and I get left with a 'eject before disconnect...' message.
At first it would appear to be a cable/USB/corrupt disk issue, BUT..........this is only happening since I tried to delete a partition using DiskUtility, (I have 2 partitions, I'll refer to the one I was trying to delete 'Partition1'), halfway through this my Mac froze. I'm using a macbookpro[Alu][intel][OSX10.8.4] and an iMac[10.8.4 again].
Symptoms....
1. On reset I found that Partition1 showed up in gray in DiskUtility, but not on the desktop.
2. Partition2 shows up fine, on desktop and in DiskUtility.
3. After a minute or so both partitions dissappear and I get my familiar 'you should have ejected' message.
All I want to do now is repair the permissions, verify the disk or delete Partition1...but because the drive keeps disappearing I'm a bit stuck. If I can just get the data from Partition2 before it all drops out then I can cope with binning the rest of the drive.
I've tried....
1. different equipment [cables, different macs (macbook and iMac), hubs and USB ports]
2. using DiskArbitrator to allow the drive to stay connected
3. using KeepDriveSpinning for the same reason
4. smashing my head against a brick wall
Please help....
Thanks in advance,
Grant
Str0ke5It certainly may be. I do not trust Western digital external drives. I've have several of them fail and it was not the physical drive that failed it was the enclosure electronics. Once I removed the physical drive from the WD enclosure and connect it with a IDE/SATA to USB adapter the actual drives were fine and I'm still using all of them.
It also might be your Mac as these WD Passport drives are USB powered and Mac's are notorious for not putting out enough power on the USB ports to complete power up some of these type drives. There are numerous thread on how a warning will come up thjat the USB port has been disabled because something it drawing to much power from it. And that is with nothing at all connected to any of the USB ports.
Only way to test it to take the drive out of the WD enclosure and use one of those IDE/SATA to USB adapters and see if the same thing happens. -
Hi Guys, I copied my iPhoto library to a second external disk. Now my version of iPhoto (5.0.4) does not display the original library on the orignal external drive. I have reinstalled the iPhoto and it seems to make 2 attempts to find the library but fails. The iPhoto menu bar is available but does not function. The screen is blank. Any help appreciated,
GethinAre you indicating that you don't get this window when you hold down the Option key while launching iPhoto?
What do you mean by "nothing happens". What library opens when you launch iPhoto normally?

Help! Broadband keeps dropping off
I need some help.I rely on my infinity to work at home. Since beginning of the week the broadband has been constantly dropping off I suspect it may have happened prior to then as tablet would be offline in morning. Now it's dropping, at times, every 20 mins. Work are very annoyed. I have to connect the systems wireless( hence why chose "good" Infinity).I'm on hub5. The internet only drops for few seconds but enough to kill everything in house. Once the hub went orange but usually blue. We have replaced the micro filter, reset hub with pin twice, changed channels, split the WiFi to 2.4 and 5Hz. Still dropping off
They say nothing wrong with the line but with our previous supplier they said we had imbalance on copper wire. I'm now suspicious it was never fixed. Called bt today but got no answers to my questions. Right at end of one hour call was told that software is to blame but it's going to take a week to fix. What do I do about work? I can't connect wired and I'm going to lose my job. Obviously my questions were outside the script ...
HOw can I be certain it's still software problem ? Is there any way I can connect to the main socket with my laptop wired to see if still dropping off rather than the hub? Can I use a different router? Is the hub less stable on an extension from master socket?
Can the customer service people actually see if there has been a millisecond drop off? They said they can see I've only had two but it's more like 5 an hour. Even happened when on phone. I can be sat within metre of hub and it still drops off. How can I tell if someone is interfering with the WiFi connection in the house? What do I need to be asking them to check regarding the copper resistance. One customer service representative said he'd reset the Cooper. Personally I can't see that happening as engineer previously picked it up by getting to the house only.
Like I said I'm getting so worried as broadband is essential for my job.

Testing Leopard on External Drive/Keeping Tiger on Internal-Any Problems?
I am currently running Tiger 10.4.11 on my internal HD and I want to install Leopard on an external drive to test it against my applications before I commit to making the switch.
Are there any problems, concerns and/or precautions I need to be aware of or take when installing Leopard to the external drive? I have SuperDuper which has cloned my Tiger drive.
Once I've installed Leopard is there anything I should be aware of when booting Leopard off of the external drive and running my applications on the data that is on my internal HD?
ThanksNo real issues. Just be sure your external HDD is partitioned with a GUID scheme, not Apple Partition Map (check that in Disk Utility).
Hope this helps... -
Itunes folder on external drive keeps reverting back to local iTunes folder
So I have all my digital music,pictures and videos stored on an external drive. I have 3 different MBP acessing these files and itunes randomely reverts back to the default local itunes folder and then I have to change and organize all over again which includes dups that I have to manage and delete later. What a pain in the arse! Does anybody have a solution that prevents this from happening, running Lion on all 3 MBP.
They are all using the library (and by that I specifically mean the library file, not just the media files) at the same time? Maybe when one is actively using the library file it prevents the others from using it or somehow interferes and makes them think the library on the external is not usuable and they revert to the internal one.
If this is set up through some fancier nettwork then probably hte person who can answer your question will want to know the details. iTunes typically revets to default when it cannot find a library on an external drive and perhaps something is happening with the network to change the identity of the drive in the way your computer perceives it.
