Time Machine Partition Corrupted on External Hard drive

I have a external hard drive partitioned into 2 sections, one for storage and the other for time machine back up of my macbook original hard drive. One day the time machine partition stopped being recognized so I tried verifying and it told me it needed to be repaired. Now it says the disk cannot be repaired and to reformat my disk. I do not want to do this because I don't want to lose whats on the other partition and I have no where else to put the data. It won't allow me to just remove the time machine partition, when I try it comes back with "disk cannot be opened". I'm lost here, is there anything that I can do without reformating the whole external hard drive?
Oh and I'm fine with losing whatevers on my time machine back up

Erasing one partition should not affect another one; however, the drive has had at least one major malfunction already, and should be expected to have more. You should immediately back up all data to another drive, including the data on the non-backup partition of the problem drive. Then, and only then, you can try fixing the unmountable partition. If the drive ever malfunctions again, replace it.

  • Time Machine backups corrupt or external hard drive failure?

    My goal today was to upgrade my MacBook Pro's HD, and to restore my system from my latest Time Machine backup which resides on an external hard drive. I installed the new hard drive, formatted it as Mac OS Extended (Journaled), and selected Restore System From Backup from Utilities. The system restore was five minutes form finishing when I received an error that the system restore could not be completed, and that I should restart my machine and try again. I did as instructed, but once the system restore process began, the screen went gray, and I was told that the Snow Leopard install could not be completed.
    Before beginning the process a third time, I ran Disk Utility from the Snow Leopard install disc and attempted to verify and repair the external (Time Machine) hard drive. The Time Machine hard drive could not be verified, nor could it be repaired. I popped in the old hard drive into my MacBook Pro, booted Snow Leopard, and ran Disk Utility, and tried again repairing the Time Machine hard drive. Here is the log of the error I received:

    Do these errors indicate that my Time Machine backups located in the Backups.backupdb are corrupt, or is the external hard drive corrupt and failing?
    The Time Machine backups are on a Maxtor OneTouch, and from what I've read, they're prone to an early demise. I've also recently noticed that my Time Machine backups started slowing. For example, I would plug in my external hard drive and if 1.3GB needed to be backed up, it would stall at 300 MB before jumping to 700 MB, stall again, then jump to 900 MB. That could be a sign of a failing hard drive, correct? If the external hard drive is failing, I can purchase a new eternal hard drive then copy the Backups.backupdb to the new hard drive, correct?
    However, if Backups.backupdb is corrupt, then from what I understand, I would have to start fresh. I would prefer to not start fresh unless there's no other option, as I would be losing almost three years worth of Time Machine backups.
    Any guidance is appreciated. Thanks!

    It's possible a heavy-duty 3rd-party utility such as +Disk Warrior+ can fix that. It's about $100, and there's no guarantee, but it's probably a good investment for the future.

    The structure of the file system is damaged.
    That may have been caused by the disk beginning to fail, but there's no way to tell for sure until you erase and reformat the disk and try to use it.

    It could, but it could also be whatever's wrong with the file structure.

    No. You can't copy corrupted backups. They're all linked together, like a database, so if anything's damaged, the whole set is suspect, and can't be copied.
    There are a couple of options:
    If the disk is physically ok, and the directory damage was recent, you might be able to restore from an earlier backup. But since you noticed problems some time ago, the damage may not be recent.
    Or, you might be able to get up and running by just installing OSX from your SL Install disk (and the 10.6.5 "combo" update). You'll be missing whatever wasn't restored in that last 5 minutes or so. Things are restored in the same order they're listed by the Finder, so it will be the last things in the last user account. You should be able to figure out where it stopped, check or delete the very last file (likely incomplete) and selectively restore as many of the remaining things as you can, via the "Star Wars" display.
    Just to make things more difficult, if the disk is failing, the more you use it, the more likely it is to get worse or fail completely.
    So your safest bet may be to install OSX, then download and install the 10.6.5 "combo" update. Info and download available at: http://support.apple.com/kb/DL1324 Be sure to do a +Repair Permissions+ via Disk Utility (in your Applications/Utilities folder) afterwards. Then recover what you can.

    Re Time Machine
    I have an external  hard drive with files I backed up manually over the past 2 years 1TB of memory.
    I am finally taking the leap to use Time machine to back everything.
    will I have to reformat that drive, thus wiping my previous back ups?
    can I split it the drive in two partitions?
    Also
    as I have two separate Macbook Pro's- one older than the other.
    OSX 10.68
    the other is
    OSX 10.75
    can I back them up separately?
    or even synch and merge files and folders etc? between the two?

    You CAN use a drive with files already on it to store Time Machine backups. But long term, that is not recommended. You do not need to reformat or re-partition the drive to do this. Once Time Machine Backups are established, you could remove the old files.
    But do not delete Time Machines files with the Finder -- that can cause it to lose its place and lose everything.
    With the cost of backup drives under US$100, it might be a better idea in the long run to get another drive. Best results from Time Machine is a drive about 3 times larger than the drive(s) you are backing up.

  • Time Machine and backing up external hard drives

    Time machine will not back external hard drives I have connected to my Mac Pro. It works fine with the 3 hard drives mounted in the computer. Is this the way Time Machine is intended to work or am I doing something wrong? Thanks in advance for your assistance.

    According to Disk Utility, GUID and AFP are both ok for a non-bootable drive with either CPU. The difference is when you want to make a volume bootable.
    Since TM volumes are not bootable, it shouldn't matter UNLESS you have some other bootable system installed on the drive.
    Right now, the drive on my Intel iMac is partitioned AFP and the one on the PPC powerbook is GUID. They both appear to be behaving themselves. The iMac has had one instance (since the last partition job) of a massive backup which occurred right after I changed the exclude list and the PPC has had no massive backups (other than the initial one). On that one, I built the exclude list BEFORE the initial backup.

  • Will Time Machine Back up an External Hard Drive Attached to my Mac Pro?

    Apple TV is GREAT, but it quickly filled up my hard drive. My thought is to take my folder that contains all of my personal files and put it on an 1TB external hard drive. I'd then "point" iTunes to where this new folder is. First, is that the right approach? Will that mess anything else up? Second, can I have Time Machine then back this external hard drive up? So, I'd like to have Time Machine back up my Mac HD and the external HD. If Time Machine won't do this, is there a good back up program for Macs that is very turnkey?
    Thanks in advance!!!

    If the drive is formatted +Mac OS Extended,+ yes. While it's connected, go to TM Preferences > Options. If it's listed in the exclusion box, just select it and click the minus sign at the bottom.
    If it's listed in gray, however, it's either formatted wrong or corrupted, and you can't remove the exclusion.

  • With Time Machine I have an external hard drive formatted with Mac

    With Time Machine I have an external hard drive formatted with Mac. The record contained files windows. How to recover?
    Serious mistake: to connect a Mac to an external drive with data (important!) Windows, the warning appears: "You want to use the disk for Time Machine?" Wrong button, so in 2-3 seconds, the disk is formatted. Now Mac "sees" the disc but empty, Windows does not see it under "My Computer" but in "Disk Management" is reported as "hard core", "healthy", "GPT protective partition" Is there a way to retrieve the files? Sorry for my English Thanks

    I'm having a difficult time following, I understand English isn't your native language. You may have good luck with Google Translate.

    Does your external hard drive have it's own power supply?  It should.
    Is your external hard drive formatted with the NTFS file system?  It won't work.
    It needs to be formatted either with Mac OS Extended or FAT32.
    (There are drivers available to add NTFS support to OS X but their quality is unknown, especially the "free" ones.)

  • Hallo ,why is it that when I delete a photo ,which is backed up by time machine and western digital external hard drive , that I am able to restore the photo okay but not the titles and descriptions . I have  a Macbook 4.1, mac osx 10.5.8 . Iphoto 7.1.5 ,

    QUESTION.
    Hallo , my question is ;whenever I delete a photo and restore it through Time machine and Western digital external hard drive , I am able to restore the photo but not the titles and descriptions . Western Digital inform me that it isn't their external hard drive problem and suggest that it is an Apple software problem ?
    I am using  a Macbook 4.1 , with Mac OSX 10.5.8 . I photo 7.1.5 , last modifie4d 01/05/2010 -universal . Should I be upgrading  Iphoto ?
    I hope that someone is able to help in this matter , as i have to restore 12000 photos !
    Thanking you in anticipation.
    Alan from Wigton

    Hallo  Kieth ,
    I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
    Thanks for your interest and advice.
    regards  - Alan

  • HT201250 How can I migrate a Time Machine backup from an external hard drive to a new TimeCapsuls?

    I just got a 2TB Time Capsule.  I want to migrate my time machine backups on an external hard drive to the new Time Capsule.  I have about 430Gb of files to back up; I don't want to wait 7-8 days for the backup, unless I have to.  I am using OS 10.7.5 (forget which cat that is).  I have mounted the TC drive as 10.0.1.1; I tried to drag and drop from old to "data" on TC, but I get the error "The volume is the wrong format for a backup."  Any ideas how I can move my old files to the new, and bypass creating a brand new backup file?
    Thanks.

    Rather than do that, which means starting over from scratch, losing all your edits, organisation and so on, why not simply use iPhoto Library Manager to revert the Library to the older version? Easier, less destructive.
    The instructions on that are here
    If you really want to start over: you can access the Originals folder simply by going to your Pictures Folder and finding the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.

  • I had to reformat my OSX 10.5.8 and i can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help

    I had to reformat my OSX 10.5.8 and I can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help? I can find the mail folder in my libraries, but the Restore Button is grayed out

    OSX treats the reformatted drive as a different one; it's the same as replacing it, and the old one is no longer connected.
    See #E3 in  Time Machine - Troubleshooting to see and restore from the "old" drive.
    And, you may not want to restore via the Finder; see the blue box in #15 of  Time Machine - Frequently Asked Questions.

  • Is there any way to create a time machine backup to an external hard drive with content already on it?  I have a hard drive that i have used for pictures but when i try to run a backup it says i need to start from a blank drive. Can i get around it?

    Is there any way to create a time machine backup to an external hard drive with content already on it?  I have a hard drive that i have used for pictures but when i try to run a backup it says i need to start from a blank drive. Can i get around it?

    It would be much better if you had separate drives for the pictures and Time Machine backups.....but, if you want to use the same drive for both purposes, temporarily move the folder with the pictures to another location for safe storage.
    Run the Time Machine backup on the hard drive and verify that everything is working correctly. Time Machine will format the disk for you in Mac OS Extended (Journaled) as part of the backup process.
    Then move the folder with the pictures back to the hard drive with the Time Machine backups.
    When you have tested to make sure that everything is working again, then and only then should you delete the folder with pictures from the temporary storage area.
    Again....it would be much better to keep Time Machine backups on a drive just for that purpose, and other data on another drive for that purpose. This is clearly one of those times when the fact that you can do something does not mean to imply that you should do it.

  • I threw out 24 time machine backups from an external hard drive into my desktop trash and now I can't empty my trash.

    I threw out 24 time machine backups from an external hard drive into my IMac desktop trash and now I can't empty my trash.

    Since you didn't mention what type of error message you were seeing, I'm going to guess on what is happening.
    I'm guessing that since you threw away Time Machine backups, that Time Machine is probably active on your Mac. There is a chance then that the files you tossed are marked as in use. You can't delete files that are in use.
    Try turning Time Machine off, then restart your Mac. Then try deleting them again.
    Once done, turn Time Machine back on.

  • Is there a way to get my photos off an old time machine backup from an external hard drive?

    Is there a way to get my photos off an old time machine backup from an external hard drive?

    You will have to connect the Time Machine HDD and click on the Icon.  You will see one folder called Backups.backupdb.  Click on that and you will have to continue until you find the home folder.  The iPhoto library (where the pictures are, not the application) will probably be in your pictures folder.  You will have to drag that to your desk top.  Then you will have access to individual images.
    Ciao.

  • Will Time Machine work with an external hard drive connected (via usb) to Airport Extreme?

    Will Time Machine work with an external hard drive connected (via usb) to Airport Extreme?

    Sorry, but this article is about 4 years old, and was printed based on preliminary information at the time.
    The bottom line here is that Apple does not officially support Time Machine backups to a drive at the USB port of the AirPort Extreme.
    If it works for you, great.
    You might want to review the Apple Support documents below, which are far more recent than the article you reference:
    http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
    http://support.apple.com/kb/HT2038
    It is supported.....
    This is NOT correct. Please do not post false information on the forums.
