Drives not unmounting; drives crashing

I have had two external hard drives, one a D2 500Gb the other a G-Tech Q 1Tb, which have problems mounting and unmounting. Both are my newest EHDs. I have a couple of others - an Iomega which is noisy but does not have any other problems, and a D2 1Tb, and also a venerable Maxtor 300Gb which just keeps chugging along on its FW400 connection and I recently moved it to my MacBookPro as a Time Machine HD.
The G-drive kept crashing and I decided to reformat it but I had great difficulty unmounting it to erase it in Disk Utility. (Also tried Disk Warrior and Tech Tool Pro). After I managed to reformat it to one partition it now will not unmount at all, even when I try to eject it. I have not tried to put any new data on it. I had originally split it into two partitions one for TimeMachine the other for a small SuperDuper backup.
The Apple Store replaced the D2 500Gb but when I tried to erase one partition in the new drive (space required because of the G-Tech failure) it also would not unmount. Currently it is not crashing, so fingers crossed it will be OK except if I want to unmount it.
Have tried FW800, FW400 and USB connections all with the same results.
Given that two brand new external drives have failed with the same problems (and the D2 1Tb is fine so far), can the cause be something to do with my AppleMac? Has anyone else had the same problems, particularly with a MacMini (also brand new)
I'll wait for an answer before I send back the G-Tech (I already have the RMA).

Thank you. This was helpful, but did not solve my problem. Yes, the G-Tech had an 800Gb partition for Time Machine and the rest was for the SuperDuper backup, but I am not sure that that was the problem.
I have partly solved the unmounting problem by ditching my Disk Utility preferences and the new LaCie D2 500 is unmounting OK now (and so are all the other hard drives).
The G-Tech is currently attached as a USB directly to my Mac (all the others are attached via a FW800 chain). When I could get it to mount and unmount again, I set it up as Time Machine but within minutes it had crashed. So it is now getting all its data zeroed out, which will take 15 hours, so I can return it to G-Tech.

  • 2009 macbook pro does not boot, restarts half way through boot. Has hard drive crashed?

    My macbook pro 2009 froze and shut off. I restarted it and only boots half way then it restarts on its own. I have tried entering cmd R to verify disk and permissions. My disk in unmounted and the SMART status says not supported. Error was found but while trying to repair it said: Disk utility stopped repairing. Disk utility can't repair this disk. Back up as many of your files as possible , reformat disk, and restoer your backed up files. I have tried to restore from time machine and it wont let me do that either. Has my hard drive crashed?
    Also, About 2 months ago i installed new RAM so I now have 8GB instead of 2GB and everything was working well up to that point.

    I am having the exact same issue. I can only log into the system in safe mode. Holding down the Shift key when turning the machine on, until the log window appears.

  • Can anyone help me to transfer everything I have on my Ipad on to a new computer.  my hard drive crashed and a new one was installed and I do not want to loose all my apps or music.  Please help

    Hi everyone,
    I am looking for help and maybe someone can help me please.  My hard drive crashed and dell installed a new one.  I have two iphones and an ipad with all my apps, music, amd photos.  Can anyone indicate me what to do so I do not lose everything when I plug in my phone.  Thanks

    Naturally you should have a recent backup of your "crashed" hard drive. If you don't, well, hopefully you've learned a lesson but that doesn't solve your current problem.
    If all your apps and media were purchased from the iTunes App Store, don't worry about them. Redownload all your apps and media, then allow iTunes to sync with and wipe your iOS devices - which will also put all the apps and media on them. You'll lose your settings, and any data which resided only on the iOS devices, and of course you'll need to organize your iOS folders and home screens and whatnot. But you won't really lose much, and without a backup this is your best choice.
    If you have media from sources other than the iTunes App Store, look at Senuti or similar applications designed to copy media from iOS devices to computers. Use that first, then sync as I described in my second paragraph above. (I mention Senuti because it's popular. There are other options which work just as well, and some are even free.)

  • I lost my iTunes library on my pc when the hard drive crashed. None of the data on the drive was recoverable and I did not have a backup. How can I get the music that resides on my ipod nano (4th generation back onto the new hard drive on my pc.

    I lost my iTunes library on my pc when the hard drive crashed. None of the data on the drive was recoverable and I did not have a backup either locally or on the cloud. Much of the music is from old vinyl and podcasts which are no longer available.
    How can I get the music that resides on my ipod nano (4th generation) back onto the new hard drive on my pc.
    I have been reluctant to install iTunes on the new hard drive out of fear that I will lose all the contents on the ipod if I try to synch to the new hard drive.
    Help!

    No backup is a huge mistake.
    You can redownload some itunes purchases in some countries:

  • I have imported and processed photo's in Lightroom 2 and kept stored files on external hard drive.  External hard drive crashed....how do I export photo's from Lightroom when it says 'file not found'?

    Folders with photo files are lost due to external hard drive crashing.  Processed photo's are still in LR.  How can I export from LR to a file (any file) that no longer exists?  Help!!!

    Well, no backups, the technical term for that is "a problem". I think from this point forward, you need to commit yourself to making regular automated backups of all of your photos and catalog file to different physical disks, no excuses.
    Your photos are not stored in Lightroom. However, Lightroom does create "previews", this is what you are seeing, but these are usually smaller and low-quality compared to the originals. There are plug-ins that can extract the previews from Lightroom. One such plug-in is here robcole.com - PreviewExporter

  • MY hard drive crashed and I had to replace it. Now when I try to sync my iPod with iTunes it says that I have to replace the old library (that is lost forever) with the new library to sync. I do not want to lose all the songs on my iPod! What can I do?

    Copy all the content on your iPod back to your PC and into iTunes. Then go ahead and sync the iPod with your new library.

  • My WD 2tb external hard drive will not unmount from my MacBook Pro.

    My WD 2tb external hard drive will not unmount from my MacBook Pro. It no longer even shows up in finder, however it does show up in Disk Utility. I have tired so many of the suggestions on the internet all to a fail.
    I keep getting the message to be sure that all applications are closed before ejecting the drive. I have no clue how to tell which appliactions are using the external drive to shut them off. I turned off Time Machiene to be safe. 
    I don't need anything on the external drive, I am just trying to erase it, save my current info, and migrate it to my new MacBook Pro.
    I have been about four days now with this issue all over the internet, in this community, and watching videos on everything and nothing about this topic to a fail.
    I think I am doomed and have lossed this external drive because of some wierd application that will NEVER close on my hard drive for it to disconnect correctly. It's annoying.
    Does anyone have a solution?

    Have you trie using another USB port? Can you test the USB ports with other USB devices to assure they are working? You may want to reinstall OS X in case there has been a driver glitch.
    Reinstall OS X without erasing the drive
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • After hard drive crash I needed to authorise my pc again. itunes tells me iphone cannot sync as pc not authorised. when I try to authorise the pc, itunes tells me pc is already authorised... what can i do?

    After a recent hard drive crash I needed to authorise my pc again. I first de-authorised all previous computers (there was no other option)
    Then I authorised the pc with the new hard drive.
    then I tried to sync
    Then itunes tells me iphone cannot sync as pc not authorised.
    when I try to authorise the pc, itunes tells me pc is already authorised...
    I have been playing this game 10 times now ... "cannot sync because pc not authorised" and then "cannot authorise as already authorised"
    what can i do?
    thanks

    yes, a few times. the number of authorised computers decreases and increases from zero to one and vice versa accordingly. yet I am still being told that it cannot sync.

  • After hard drive crash, Pages app brought over, and upgrade to snow leopard installed, Pages would not launch.  Re-downloaded the 3.0.3 update and Pages launched, but will not open any documents or start new document.

    After a hard-drive crash, Pages application was brought over from the old hard drive, and upgraded to snow leopard.  However, Pages would not launch.  I do not have the disks and the computer was given to me by my son with iWork 08 installed, so I do not have the ability to re-install using Purchases.  I re-installed the update 3.0.3, which I already had, but thought it worth a try.  That enabled Pages to launch, but it will not open a new or old document.  I can see in preview the document, but it will not open.  Any suggestions besides repurchasing Pages.  I've just put out a lot of money for a new hard drive and retrieval of apps and docs from the old hard drive and would like not to have to put more money in it. 
    Thanks for any suggestions.

    You can not simply drag over Pages, particularly if it was perhaps damaged in a crash.
    As it was only Pages '08 it may be time to upgrade to Pages '09 from the App Store. It is not that expensive and will allow you to install it on any Mac sharing the same Apple I.D. and protect you from a repeat of this problem.
    There are free alternatives to Pages if you are hard strapped, it depends on what you are using Pages for, it is not the only option by far.

    Can someone please help a friend of mine get a permanent registration key (not a trial key that expires in 30 days) to replace his lost registration key for Adobe Photoshop CS2? His previous hard drive crashed and he no longer has his registration key. This is vital for his wedding business.

    Thanks to everyone for the tips on my CS2 question. It turns out in the end it was some plug-in filter software that was causing the glitch, not a lack of an Adobe registration key. As for why he still uses CS2, it does the job for him, so that's all he needs.
