Hi Chris:
I had to go through the painful process of recovering lost files on an
ext FS (twice!) and it really is a PITA. Eventually I discovered that my
problems
were card-specific to having a kernel built for dual-processors. Nevertheless,
if it werent for the fact that the data was really, really, important to me
(digital photos, personal coding libraries, etc..) I wouldnt have bothered.
Allow for spending bunches of time in inode hell:(
I used ext2utils (works for ext3), tried to restore
a copy of the superblock, then had to go through every inode, ID'ing dirs from
files, until the system
locked up on un-recoverable ones; I had to re-boot the system numerous times
because it locks up ( Input/output error)
, but i did get about 70% of the FS's contents.
I had a corrupt ext2 filesystem w/an error message
corrup superblock - linux A block group is missing an inode table"
Below are the proggy's I used:

I determined where the copies of the superblock are kept:
I eventually had to create a list of
all inodes in the FS, allowing for system lock-up when it encountered a bad
block. then I ran stat_inodes.pl to get a dump of them, then i ran a script i
created to ID the inodes and determine their proper names.
If you find you need to go to these lengths then i'll be happy to get back with
the particulars
of what exactly i did before blowing away the FS. (the drive was good and still
runs today)
