where to RTFM about disk errors

[Mark Street]

On ext2 filesystems backup superblocks occur every 8192 bytes so you should 
have one at 8193 and 16385 ..... etc.

e2fsck -b 16385 /dev/hd**

You might want to check for badblocks also.... time consuming...  give 
e2fsck the -c option to have it check for bad blocks before it checks the 
filesystem.
