     fdisk tells me:

     There are no hardware errors in the boot log (dmesg).  The only 
error is that it can't find the ext3 fs that was on that drive.  
Unfortunately, it's not a drive I can simply reformat and call it a 
day.  There's data on it I need.

     When I try to mount it, I get: hfs: unable to find HFS+ 
superblock.  Obviously that's not right as the drive was formatted as an 
ext3.  So if I force it, I get this:

----------
mount -t ext3 /dev/hde1 /mnt/hde1
mount: wrong fs type, bad option, bad superblock on /dev/hde1,
        missing codepage or other error
        In some cases useful info is found in syslog - try
        dmesg | tail  or so
----------

     So, is this just an indication that the partition table is hosed?  
Is there anything, any tool, any way of reading the data off of this 
drive and put it elsewhere?
Have you tried using an alternate superblock?
