ZAR Hangs at 91.9%

[Freak4Dell]

One of my external hard drives got corrupted a few days ago, and somebody recommended I try ZAR. I ran the program once, and it found a lot of files, and I started copying them to another drive. It looked like it was going to take a while (about 200 GB worth of data), so I let the computer sit and went to sleep. When I woke up, the copying had stopped about half way through. The bottom of the window showed a varied processor usage of 0-3%, and the disk read speed said 0.0MB/sec. I figured something had just gone wrong, and I started the scan again. This time, it got 91% in the scan, and the processor usage and disk read speed dropped to zero. Tried it again, same result. Then I thought I would just make an image of the disk, mount it, and copy files that way. That stopped moving at 91.9%. It seems that no matter what I do, the process hangs at 91%. If the sectors are bad, shouldn't it just skip them? The first scan that I did gave me two map blocks worth of bad sectors, but it skipped them and finished the scan.

If I do a quick format on the drive, and then run the scan again, will I be able to get my files back?

Quick format is not going to help.

If you got a disk image which is 91% complete, first try scanning this image to see if it contains at least part of the files.

Thanks for the reply. I tried loading the image, and I get this message:

UNABLE TO CONTINUE:
Unsupported filesystem type
Unable to continue processing, program will now terminate.
Not a bug - data is probably beyond repair, or something is misconfigured.

:(

In "Advanced Configuration" under "Common filesystem analysis" change "Quick scan" from "Automatic" to "Disabled" and try to rescan the drive, to see if it helps to get past 91.9%?

[Freak4Dell]

Nope...that didn't work. Any other ideas?

If possible, can you get the hard drive out of the enclosure and connect directly to the motherboard, then retry?
This would help if it is the USB enclosure that fails, rather than a drive itself. Generally, we advise to remove the drive from the enclosure if you are recovering an external drive (http://www.external-drive-recovery-guide.com/usb-vs-ide.aspx).

Thanks for the suggestion...I put the hard drive into an older desktop, and it was able to read the drive through Windows without any problems. I guess the enclosure was messed up, but that doesn't explain why it didn't work when I switched enclosures. Oh well...everything is okay now.
