Mac Fanatic Level 1 Level 1 (115 points)

My hardrive is very unstable.

 

I am trying to copy off the user folder at minimum. 

 

I am able to pull the drive out of the G5 and put it in a USB external enclosure.

 

I can get it to show up as an external but after a few minutes of copying the files off the drives crashes.

 

I have tried booting into singel user mode but I get a "error loading kernel 'mach_kernel' (0x7).

See attached photo.

 

1. Is there anything else I can do to copy the files off?

2. Would Data Rescue 3 help?

    You are trying to boot from the drive? It would appear that the OS is hosed, thus preventing boot.

     

    You should boot to a seperate drive and pull the user files off in a drag and drop fashion if at all possible.

     

    Data Rescue 3 would definitely be able to pull the files, though the resource forks will be gone, with the need to sort remaining.

    I wasn't very clear. 

     

    I have booted from another mac and have mounted the bad drive that is now in a USB enclosure. 

     

    I can start to copy files off and have also tried DR3 but the drives disconnects/unmounts part way through.

    Is the drive getting too hot?

     

    Can you copy smaller portions off it?

     

    If you have DiskWarrior try holding the Option/alt key while selecting Rebuild, the Scavenge, which can build an alternate directory that can allow backing up from that directory... it's worked a couple of times when nothing else did. Can takes days trying sometimes though.

  • Mac Fanatic Level 1 Level 1 (115 points)

    Yes the drive is getting hot and I thought of that last night but it was too late to go digging in storage for a fan.  I'll try that tonight.

     

    Maybe my diskwarrior disc is scratched, becasue it will not boot while holding down the C key.  I'll have to buy a new one.

  • BDAqua Level 10 Level 10 (120,935 points)

    I'd for sure work on the cooling, can you run it with the USB case open? And a Fan?

  • Mac Fanatic Level 1 Level 1 (115 points)

    Yes, I can use one of these and a fan: http://eshop.macsales.com/item/NewerTech/U3NVSPATA/

  • BDAqua Level 10 Level 10 (120,935 points)

    That should help, good luck.

    I tried pointing a fan on the drive but there was no change in the amount of time before the drive discounects.  I even tried sitting the raw drive on a small box fan but it made no difference.

     

    Can I reinstall the OS on the drive to fix this issue?

  • BDAqua Level 10 Level 10 (120,935 points)

    I doubt it, but try this...

     

      1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.

       2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)

          *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

       3. Click the Erase tab.

       4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.

       5. Select your Mac OS X volume.

       6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion hopefully you'll be able to install.

    Sorry, again I am not being clear.

     

    Is it possible to reinstall/upgrade the OS on the bad drive without erasing the drive, in order to get the drive to be stable enough to copy off the user folder?

     

    I can put the Leopard disc in my macbook and hook up the bad drive via usb.

    You can "Archive and Install: Preserving User Settings", with the "Preserve User Settings" being very important.

    This retains all your data and such in a "Previous System" folder and installs a new OS X.

    http://support.apple.com/kb/ht1710

     

    As to whether or not the drive will take the "abuse", that remains to be seen.

  • Mac Fanatic Level 1 Level 1 (115 points)

    Do you think "Archive and Install: Preserving User Settings" would make the drive stable enough to copy off the user folder?

     

    I do not want to risk losing the user folder contents.  I can see that everything appears to be there, but I only get 3-4 minutes before the bad drive disconnects.

  • Mac Fanatic Level 1 Level 1 (115 points)

    I finally got Diskwarrior 4.4 and am trying scavenge right now....

  • japamac Level 7 Level 7 (24,390 points)

    Do you think "Archive and Install: Preserving User Settings" would make the drive stable enough to copy off the user folder?

     

    It is probable that it will if the issue is indeed just missing OS X files.

    It can also help in the case of corrupt files.

    It is very hard to say, though, not knowing any more about the issue than what is said here...

     

    Call it a YMMV type of deal (Your Mileage May Vary).

    I do not want to risk losing the user folder contents.  I can see that everything appears to be there, but I only get 3-4 minutes before the bad drive disconnects.

    Any writing on or heavy use of a compromised disk is risky.

    If the drive "goes away" during the A&I, things will likely get worse as far as file availability.

     

    I would backup/copy whatever I could, even if it is one file/one document/one photo at a time, before the A&I.

     

    Otherwise..... well, the "otherwise" makes me nervous.........
