Repairing corrupted IIgs hardisk?

[Mitchell Spector <mitch2gs@hotmail.com>]

    Rather annoyed at the moment. Went to cold boot my IIgs
tonight after a lock up only to find, mysteriously, the entire hardisk 
wiped itself out! The RamFAST still detects the SCSI hardisk 
but it cannot see any of its partitions (it's just a large unpartitioned 
device now). I only *just* recovered a physical hardisk failure from
last year.

    I tried using ProSel 16's volume repair utility to try and examine 
the drive, but it just gives up and reports a cryptic error message:

"MLI error #$2F - Error occurred on  block 2 - Program aborted"

    Is there any other software worth trying, perhaps something 
like Universe Master? Thankfully I created backup of all my
partitions on Zip disks a few months ago, but that is rather a
pain restoring. Just wondering what options I might try to repair
the partition map on the drive before reformatting.

...I wonder if this wasn't a result of my ZipGS constantly crashing
or the lose/intermittently ADB connector on my keyboard. Was 
planning to do something about those weeks ago but got 
sidetracked. :)
