I've read a fair amount including several sections of *Understanding the Linux Kernel* and I will keep reading.

For example: bohr:/home/anthony# mke2fs -F -n /dev/sda1 mke2fs 1.27 (8-Mar-2002) ... snip ... Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736 If you don't have any superblocks left, read about the -S option, which can give you new ones. Any fsck on a file system where the primary superblock was destroyed would (I think) error out. Also, there is e2recover which might help, too. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
