Recovery of 40GB disk running for 20 hours

[Wedgie]

i have been trying to recover a 40GB disk that had totally failed and was not being recognised as a formatted drive, let alone bootable. ZAR had managed to parse the disk and recognise the disk as FAT32 within 5 hours. Ever since then it has been displaying a status of Parsing the Filesystem: Reading directories (0%) and has located 0 files and 0 directories. I'm not convinced that is doing anything at all. How can I tell? How long should I let this run before giving it up as a totally broken disk? It woudn't be so bad if the backup set that I had taken with Norton Ghost wasn't also corrupt! :(

This thread (http://z-a-recovery.com/data-recovery-forum/showthread.php?t=79) is a good starting point. Scroll down for the section titled "What we need to investigate a filesystem analysis problem" - this provides list of things we need to get to investigate.

[Alexey V. Gubin]

Looking into it. Seems like a bug.

[Alexey V. Gubin]

The issue might be the same as the one here (http://z-a-recovery.com/data-recovery-forum/showpost.php?p=224&postcount=14), but no certainity.
Could you please try this:

Download the updated executable at http://www.z-a-recovery.com/tt/zar-82-015.exe
Save it as zar.exe into c:\Program Files\ZAR, overwriting the existing file
Retry the run.In case it fails again, I'd like to see what its recorded at the end of log.

[Wedgie]

OK, have downloaded this now and am starting the process of reanalyszing the disk. If it's anything like last time it will be about 5 hours before reachng the stage where the programme locked up last time. Will let you know the outcome.

[Wedgie]

So, we progressed a little further this time. Now I have a window which tells me that the application has found 0 file and 0 folders. This is the end of the log file.
