In the mean time, fsck.ext4 is not liking our filesystem. Group descriptor 353 checksum is invalid. Fix? yes Pass 2: CheckingEntry 'spice-and-wolf-si-tendra-segunda-temporada' in /liamsito1234/cibercomics.com/wp-content/cache/supercache/www.cibercomics.com/2008/10/05 (2152305) references inode 2901322 in group 354 where _INODE_UNINIT is set.

Clear? yes /dev/sdb1: e2fsck canceled. e2fsck: aborted Same block group each run through, different inode. I ran e2image and produced the following file: http://ext4dev.dreamhosters.com/watanabe-home-2008-11-13-1712.e2image.bz2 Unfortunately I cannot mount the filesystem right now due to: EXT4-fs: ext4_check_descriptors: Checksum for group 353 failed (23397!=52411) EXT4-fs: group descriptors corrupted! mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so Is there any hope for recovery of any of this data? Also, to append my prior email, this is the original error from the machine: Nov 13 15:58:49 watanabe EXT4-fs error (device sdb1): htree_dirblock_to_tree: bad entry in directory #51577: rec_len % 4 != 0 - offset=0, inode=943022112, rec_len=13614, name_len=52 Nov 13 15:58:49 watanabe Aborting journal on device sdb1:8.
