Hi, my first post. I've search the net for similar problems but nothing exact.

I have a Maxtor OneTouch 4 (1TB)that just returned cos I got it exchanged. While it was being exchanged, I used a Maxtor OneTouch (640GB). I had transferred everything from my 1TB to the 640GB.

Now that the 1TB's back, I want to transfer everything back. But when I try to transfer anything from the 640GB to the 1TB, an error message appears saying "operation can't be completed because an item "(of same name)" already exist."

After I click OK on the error message, only the folder gets copied over to the 1TB but NONE of its contents.

This only happens when I transfer folders. If I were to transfer individual files, e.g a picture, it's successful.

Things that do work:
- transferring files and folders from computer to both HDDs
- transferring files and folders from either HDDs to computer

So the only problem is transfers between both HDDs.

I read some thread that repairing permissions might help but when I enter Disk Utility, "Verify Disk permissions" or "Repair Disk Permissions" are both greyed out.

Does anybody have experience with this problem? Please help, the 640GB is exploding!

Thanks in advance!

Macbook (white), Mac OS X (10.6.2)

    you should repair disk, not permissions. repair both external disks. then try again.

    also, if you really want to copy everything from one disk to another you can just clone it. you can use the restore tab in disk utility or a 3rd party cloner like CCCloner or Superduper. this works better than copying massive amounts of data via finder.

    But will repairing the disks change anything on the disks?

    thanks for your prompt reply!

    no. it will fix file system problems if there are any.

    you mean during the verifying and repairing? no, both were smooth and fast.

    sorry, I don't know what's going on then. could be some strange hardware issue with the drives. check with manufacturers of both drives to see if there require any special drivers and if there are updates for those. other than that I can only suggest using CCCloner or superduper to move all the stuff from the old drive to the new one.

    If you still have everything on the 640GB, have you tried using Disk Utility to erase 1TB HHD and reformat before trying to copy the data back? have you tried using the restore option within Disk Utility to copy the data back instead of doing it manually?

    "have you tried using Disk Utility to erase 1TB HHD and reformat before trying to copy the data back?"

    Yes, I had to format the 1TB to FAT before I use it.

    "have you tried using the restore option within Disk Utility to copy the data back instead of doing it manually?"

    There's nothing on the 1TB to restore because I sent it in for warranty exchange. So its brand new, nothing in it.

    whoa there. why did you format the drive FAT? that's an obsolete windows drive format and OS X is known to have various issues with it. this may easily account for your problems. strongly suggest you reformat the drive mac os extended.

    he was suggesting that you use the restore tab in disk utility to copy the 640GB drive to the new 1TB one. that's what I suggested too but I mentioned using superduper or CCCloner.

    but you really should reformat the drive first. the only reason to use FAT is if you want to use the drive from both mac and windows. but then you'll likely have to live with the quirks of FAT and OS X.

    i use fat cos i want to use it for my windows partition as well (boot camp). before i sent my 1TB for an exchange (the cable was screwed and it kept ejecting on its own so i changed, just to be safe), it was in fat for a whole year and no problem.

    I'm really not familiar with the restore tab. care to walk me through it?

    the use of the restore tab is quite simple. click on the restore tab in disk utility. drag the source drive to the source field, target drive to the target field, check the box to erase the destination (if you want) and hit 'restore".
