Moving Your Mac Leopard Time Machine to a New Drive

Transfer the files

Note: The sections “Formatting the new hard drive”, “Transfer the files”, and “Transfer Problems” narrate the problems I had while trying to just copy files… see the following section, “Use Disk Utility Instead”, for enumerated instructions on how I actually solved the problem.

After the drive was formatted, I went into finder and selected all of the files except for

Backups.backupdb

Selecting the old files and folders

And I moved them to the / directory of the new disk. That was quick. Then I selected the

Backups.backupdb

Select the backup folder to copy

folder and dragged it into my new disk. This took a while in preparing to copy.

Transfer Problems

Note: The sections “Formatting the new hard drive”, “Transfer the files”, and “Transfer Problems” narrate the problems I had while trying to just copy files… see the following section, “Use Disk Utility Instead”, for enumerated instructions on how I actually solved the problem.

Freezing

In some of my attempts this window would freeze and the number of items would not increase and it would not move to the next phase. I had to restart Finder and try again.

Asking about the administrator

At one point, my new external hard drive accidentally became unplugged and I got the standard “Don’t remove your drive!” warning. My copy had been preparing for some time, so either coincidentally or maybe because of this the Finder copy said: You may need to enter the name and password for an administrator on this computer to change the item named “Backups.backupdb”.

asking

and I said continue. Then, it made that “pang” sound that Finder does when it copies a file, yet only the top folder was copied, not the contents.

So I tried copying again…

The next page goes over how I used Disk Utility instead.

    Disk Utility doesn’t do Time Capsule (afp) volumes.
    So I tried /usr/bin/ditto and got:

    rt1 root# ditto /Volumes/Backup2/Backups.backupdb /Volumes/rt1
    ditto: /Volumes/rt1/rt’s MacBook Pro/2008-01-11-160545/iTunes/.com.apple.timemachine.supported: Operation not supported

    Thanks for the walkthrough. I just did this for my wife’s iMac and just let the backups go because I could not figure out a way to get them to the new drive I bought. Fortunately, I keep a Mirra server with a total backup of her machine so it was no real loss when I replaced her timemachine drive.

    Anyway my old time machine drive on my MacBook Pro started giving me the “I’m out of space” from Time Machine yesterday so I ordered a WD My Book Studio 750 GB for my mac so your article is a lifesaver as I have no other backup except for My Pictures and My Music on DVD.

    Worked a treat – took about an hour to move 50Gb to a 500Gb drive.

    Thanks.

    I have tried the disk utillity technique four times. Same result:

    Note: I am trying to move a very full 250gb time machine back up onto a 1tb drive and seemlessly continue backing up through time machine.

    1. I get an error that says “Could not restore – operation timed out”
    2. The 1tb drive ends up a carbon copy of the previous drive. The problem is that my computer sees the 1tb drive as an almost full 250gb drive.

    Please help!

    Blair,

    Did you check the Erase destination box? (Step 6)

    Can you tell how many partitions are on your 1TB drive when you complete? (If you mac sees only a 250GB, it might also see a ~750GB partition, too)

    Thank you!

    Flawless. I transferred a Time Machine backup volume from a WD Passport 160 Gig drive to a 300 Gig partition on a WD 1 TB drive, no problems whatsoever.

    Thanks again for the tip!

    Thanks for the excellent article. I want to offer the following experience I had for those who want to use the disk for Windows compatibality.

    In addition to using my external drive (WD passport essentials 500GB) as my time machine, I wanted to have a FAT partition so I could use it transfer files from my mac to a Windows XP machine. I couldn’t find the answers spelled out, so I experimented, and it worked.
    When I partitioned the drive I created a Mac OS extended format for the large (main) partition and a FAT32 format for a 32GB partition. This caused the Disk Utility to force me to select Master Boot Record (the 3rd option) instead of the GUID which I would have otherwise selected for my Intel based macbook. I was concerned that Time Machine would insist on GUID, preventing me from adding the FAT partition. As I am writing these words, Time Machine is performing its first backup on the new drive in the mac os extended partition, without complaint. The FAT partition rests quietly alongside, while the disk was formatted with the MBR option. I hope this saves time for others with the same need.

    Thanks for the help!

    I’ve been trying to transfer my backup for about an hour now with no luck. I kept getting Error Code -1426, which I think is some kind of Permissions error, but your tutorial worked fine for me.

  10. On Sep 5, 2009 Walter said:

    Can’t initiate the copy. After permissions validation, gives me this error

    ‘Could not validate source – bad file descriptor.’

    P.S. I’m on 10.6

  12. On Sep 7, 2009 Jake D said:

    I haven’t run this on 10.6. Is anybody else having this problem?

  13. On Sep 10, 2009 WT said:

    I am having this same issue in 10.6 (never tried it in 10.5 so I do not know if it is a unique 10.6 issue or not). I tried to have Disk Utility repair the disk, to no avail.

  14. On Sep 10, 2009 Dean P said:

    I, too, am getting the error “Could not validate source – Bad file descriptor” when I try to create a backup in 10.6 through Disk Utility. I’ve also tried SuperDuper! and had the system simply shut down in the middle of the process with no warning or error message.

  15. On Sep 12, 2009 Jake D said:

    I don’t have the hardware right now to try this on 10.6 (I just upgraded).

    Try using the Snow Leopard Install Disk to run Disk Utility. This involves restarting your mac with the CD already inserted, then exiting the wizard but running Disk Utility from the CD.

    Also, I see there is a Software Update to 10.6.1, maybe that will help.

    Please let me know if that works!

  16. On Oct 27, 2009 Jan G said:

    Same issue here, when I try starting the restore all I get is “Could not validate source – Bad file descriptor”, on 10.6.1 – only idea I have left is to go GUI free and try dd on the terminal, but have no idea what that will give as the source and target drives have different sizes.

    Anyone who already tried that? Any hints would be greatly appreciated :)

    And great article, thanks!

    Same issue here. “Could not validate source – Bad file descriptor” but Disk Utility reports no errors on this disk. Also ran Tech Tool Pro 5 and it reported no errors. Anyone found away to get around this?

  18. On Jan 2, 2010 Kayte said:

    The Disk Utility solution worked great for me. Thanks!

  19. On Jan 16, 2010 Sid said:

    Thanks!!!

    I successfully used Disk Utility to move 377 GB of Time Machine backups from a 500 GB Time Capsule (by Ethernet) to a new La Cie 1 TB external hard drive (by USB). Copying took about 5 hours. I am using a MacBook Pro with 10.6.2 installed. BTW I did not need to use the Snow Leopard Install Disk to run Disk Utility.

  20. On Jan 22, 2010 Erk said:

    to solve the bad file descriptor error….
    make sure you deselect the current time machine drive from the tm preferences (select “none”) before you try to restore.

  21. On Mar 4, 2010 Bung said:

    Sorry, Erk. That didn’t work. Still getting “Could not validate source – Bad file descriptor”

  22. On Mar 4, 2010 Bung said:

    Aha – but ejecting both drives and doing it on another machine with 10.5.8 seems to be working.

  23. On Mar 4, 2010 Eric said:

    Doesn’t work for me either. Funny different everyone’s experiences are. Snow Leopard was a big wake-up call for me. I’m seeing, among other things, that the manufacturer of a drive can make a difference with Apple OS/X. Wow. That’s incredible.

    Bad File Descriptor problem: Any other ideas? I’m fresh out.

  24. On Mar 25, 2010 Walterhisownself said:

    I get the same “Could not validate source – Bad file descriptor” using Snow Leopard 10.6.2. My new external drive is a 1TB LaCie and the old one is a 500GB acomdata.

    Don’t know what to do to fix this. I’m just going to burn the last back up to DVD and then start with the new 1TB drive. The old one will be erased.

    Tried 1.000 times on 10.6 (MacbookPro ). Always with the “bad file description” error.

    Found an “old” 10.5 (PPC). Just started the DiskUtility and it looks like it’s doing something. Calculating time …

    Will let you know!
