I have searched the faq and here and cant really find anything on this but any way I was prepairing a used drive for my empeg and got this error: Writing inode tables: done
Writing superblocks and filesystem accounting information: done

real 0m42.752s
user 0m0.300s
sys 0m2.230s
set_blocksize: b_count 1, dev ide0(3,4), block 1!
EXT2-fs error (device ide0(3,4)): ext2_check_descriptors: Block bitmap for group

EXT2-fs: group descriptors corrupted !
mount: wrong fs type, bad option, bad superblock on /dev/hda4,
or too many mounted file systems
hdstress.cpp 189 ( 19): Poll result=0 on fd=5
hdstress.cpp 189 ( 19): Poll result=0 on fd=5
Stressing /dev/hda: Spinning down.

What is that EXT2-fs error? and how do i fix it. I went ahead and installed b13 anyway to see what happens and it boots up but it has that same EXT2-fs error in the boot log: Tried to mount /dev/hda4 as reiserfs but got error 19
EXT2-fs error (device ide0(3,4)): ext2_check_descriptors: Block bitmap for group
64 not in group (block 2)!
Remounting filesystem read-only
EXT2-fs: group descriptors corrupted !
Tried to mount /dev/hda4 as ext2 but got error 22
Error mounting partitions (possibly already mounted)

everything else in the bootlog seems to look ok


UPDATE
Hmm.. now I m really confused, I did the whole thing over again starting with the developer image, and got the same error at first but them after installing beta13 the error went away, any ideas ? should I trust the drive?
