I am trying to copy a disk using restore on disk utility. The disk verified just fine, and it says it is copying files but nothing is happening.

I know something is breaking in my computer because It won't boot up normally. and I just want to get my files from the disk. What do I do?

    Ok, so you have a external drive your trying to transfer files too, can it be erased?


    Becuase while c booted off the 10.5/10.6 disk (you didn't mention your OS X version or hardware) you can set up the external drive (under the partition tab)


    Options: GUID  Format: OS X Extended (J) and click apply.


    Then Erase with Security option Zero all Data to eliminate any poential bad sectors (takes a bit to complete)


    Then install 10.5/10.6 onto the external drive and reboot holding the option key down, you can select the external to boot from


    While booted from the external drive, you can access the internal drive and recover your files.

    Run Data Rescue $99 on the second Mac in Target mode on the sick one, it will  recover what you can from the 1's and 0's of the bits themselves, you'll need another external hard drive (empty) to send the files too as not to clog the second Mac HD up with stuff.


    Once you've got your files off, try the c boot erase/zero from the 10.6 disk to wipe the drive.

    When you try a copy, open the Console utility and under the File menu try Open System Log and Open Console Log. While it is trying to copy, see if there are error messages appearing in the logs. When I had a bad disk, the logs would fill up with repeated i/o errors.
