OS X V10.7 Lion :: External HDD Ejecting During TM Backup?
Mar 12, 2012
This is proving a bit a bit of a puzzle to me. I have a 1TB External LaCie hard drive connected directly to my iMac via USB. It has two partitions, both empty. I set the back-up going and it works for a while and then I get:"Time Machine could not complete the backup. The backup disk may have been ejected or disconnected from your computer." Â
I've amended the Energy Saver settings in the system preferences to keep the machine on given the length of time the first update is going to take, but this doesn't seem to make any difference - and I'm not even touching it! I promise! Then the drive disappears from the disk utility. I then have to turn it off and then on again to get it back. I have the TM widget and this is what it has to say:Â
Starting standard backup
Backing up to: /Volumes/Time Machine backup 70/Backups.backupdb
Ownership is disabled on the backup destination volume. Enabling.
Backup content size: 196.7 GB excluded items size: 1.7 GB for volume Macintosh HD
233.92 GB required (including padding), 465.34 GB available

My time machine disk keeps ejecting itself in the middle of a backup. I have to reinsert it several times before it completes a backup.Â

I have a external HD which has always worked fine under snow leopard. Since upgrading to lion I keep getting the following message The identity of the backup disk has changed since the previous backup.The disk may have been replaced or erased, or someone may be trying to trick your computer into backing up to the wrong disk. And after this the drive disappears from the desktop appearing agian only after restart. What can I do do rectify this? Delete and re-intialise the drive?

i have a Beyond Micro mobile disk USB external hard drive connected to my imac running Leopard. Once in a while during it randomly ejects by itself and i get the "Unsafe Removal" warning pop up. I don't do anything to the drive at all. Is it a software thing? or is it about to bail?

I have a 1 TB WD external hard drive I store my music and videos on. I have noticed that the hard drive will randomly eject itself causing me to have to turn the external hard drive off and back on for the iMac to mount it again. I have a new iMac i5 and had a 24" 2.4 GHz iMac previously. I was using the firewire port on my previous iMac before and would occasionally experience this problem. However, having to use the USB port on the new iMac it is occurring on a daily basis. I have tried different ports on the back of the iMac thinking it was a USB problem, but that didn't seem to help. I have run disk utility and it says the drive is in good health.

All software uptodate. I have strange issue with USB ports. After ejecting USB drive (external HDD, powered by USB bus), which worked perfectly, USB port does not recognize anything, nor providing power. Turning MBP off and then booting back solves this issue.

I have a Seagate 500gb GoFlex external drive, which I'm using with Time Machine to backup my MacBook Pro. Now, when ever I eject the drive (by right clicking or dragging to trash) it appears to disconnect from my MacBook, but the drive itself continues running, i.e., the lights stay on and I can still here the fans / drive whirring away. This continues unless I pull the USB cable out. Is this normal? Should the drive completely shutdown upon ejecting? Or is simply 'ejecting' from the MacBook enough for 'safe' removal?

I've seen several discussions on external drives randomly ejecting, but didn't see any concise resolution. I have a Western Digital Passport, P/N WD320ME-01 2209A, using the OEM USB (2.0 I think) cable (~12 inches long). My ~4 year old mac book is running OSX 10.7.3. I use this drive for Time Machine B/U. Seemed to work ok (no ejects) when Leopard was the OS, but, after going to Snow Leopard, and now Lion, I get 'disk improperly ejected' errors when trying to run TM, or ever Repair under Disk Utilities. I did get one good TM back up, under Lion, after reformating the drive [extended (journaled)], but the next time I tried to run TM I started getting the 'improperly ejected' errors. Don't know if there is an issue with Lion (and earlier SL), or with WD drives. The fact that it originally worked leads

I have just installed a 240GB LaCie Little Big Disk Thunderbold SSD as a boot drive for my 2011 iMac (which contains only the 7,200 prm HDD). This has improved read/write speeds dramatically. I have transferred all my data and applications to the external drive in order to see the full benefit of the SSD.
However, I had not considered Time Machine. I thought it would simply be a matter of identifying the external drive and then connecting to the Time Capsule. However, the external drive is not visible in Time Machine set up and I suspect there could be a good reason: that it is not possible.

I used my external hard drive to store important documents off of my previous Mac. None of these documents are on my new Mac. Will I lose these docs if Time Machine backs up to this external hard drive? Will Time Machine save over those docs?

I am trying to get Time Machine to backup my external hard drive. I have the external drive formated as Mac OS Extended (journaled) and I have also removed the drive from the Excluded list.I put some 'test' files on the external drive and told TM to do a backup and when it is finished the only way I can see my external hard drive in TM is if it is connected to the computer. It doesn't seem to be backed up anywhere in TM that I can see.

I noticed that Time Machine backs up the system ever so often. What happens if I disconnect the external hard drive I'm using as the back up and Time Machine tries to initiate a back up? Will it corrupt anything?

I just installed a Lacie 1TB P'9231, with the instruction from Apple Tech Support.Â
Still my back ups are failing. I have 625MB available, but it says back up requires 45.3GB of space. What do I do?

I had a IBook G4 and an external hard drive as its back up.IBook running something like Snow Lepord, anyway I have a Intel Macbook now with Lion, Ive been told here there is a possible confliction between the AMP external harddrive and lion.I will say a few times I have for limited time been able to access the drive on the newer MacBook, but then Lion (I think) drops it.Â

my TM wil not back up! It states that this backup is too large for the backup disk. The back up disk requires 573.50 GB but only 225.23 GB are available. The TM needs work space on the backup disk, in addition to the space required to store backups. Upen TM perferences to select a LARGER backup disk or make the backup smaller by excluding file.Â
Okay I;m sorry but obvioulsy I dont get this. I've never called Apple for help! I have every product they sell practically including Protection Plans I never used and no one will help me with this. My MAC is starting to have black or white screens and i can hear it running but it will not do anything so i have to reboot it, it screws up Enturage and then I have to rebuild that ( 5 times this year) anyway... I would like to back everything up- can I delete everything on the Time Capsule or Time Machine; god I dont even know what it is called Im so MAD... help if you can please. I'm going to have to take this to the genius people at the store and probably buy another computer but like before they will not save my files.

I just did a zero delete on my computer and only have CS5 master suite and Lightroom on my computer now (MacBook Pro 2010). I have 2 external harddrives I'm using. Both are 1TB. I have the Master drive with everything on it, and I want to use the 2nd drive to keep an updated copy of everything. Then I have a 3rd Hard drive, that I want to backup the 2nd backup and keep that off site. What is the best way to go about this?

I have a Western Digital My Book World Edition as a NAS. I also got an external drive (a Western Digital Elements Desktop) to which I want to backup everything from the NAS, and then store it at a different location. My problem is that I can't find any software that does this, everything I find seems to work the other way around (using the NAS as a backup). It would be sweet to have the backup working as automatically and simple as possible, so when I wan't to backup my files the next time, it should only copy the files that have changed or are new. Is there a solution to this problem? I'm using a Macbook Pro with Snow Leopard.

What backup solutions are available for backing up two drives on to one backup drive without causing any confusion?
My setup consists of:
- Powerbook (80 GB)
- external Firewire drive (160 GB)
- external Firewire drive (500 GB) for backup
I'm running MacOS 10.4.11, so please don't suggest Time Machine.
