Hi,
Use "dumpe2fs -b >/tmp/badblocks" to get a list of the bad blocks in
/tmp/badblocks.
All that returns is Couldn't find valid filesystem superblock in the
file.
Edit that file and add an entry for block 1, then
run "badblocks -i /tmp/badblocks" to mark the block as bad.
Given the above error, how am I supposed to add an entry for that? The
man page for badblocks isn't exactly revealing much.
TTFN

The ext2/3 file system seems to be able to bypass bad blocks only in
'normal' places, not in superblocks or group descriptors. I have an old
'80Gb' drive with 5G of bad blocks on it I am able to use successfully
only by creating an unused partition to shift the superblock into a good
block, and formatting the remaining 70Gb with 'mke2fs -c -c ...' (of
course I don't rely on it; it's in a USB enclosure I use for large
off-net file transfers).
