Normally I would not be coming here for help, but I made a big mistake and frankly don't think any other group has sufficient kernel/ext4 knowledge to help me. My partition table used to look like this: /dev/sda1 start:6144 end:10743 /dev/sda2 start:10743 end:10946 I deleted /dev/sda1 on a live system and recreated it like so: /dev/sda1 start:1 end:10742 And rebooted. Please don't ask why I did that, or how it happened. It is a long story and was an accident. Needless to say, it really messed things up. I booted a rescue disk and changed the table back to this: /dev/sda1 start:6144 end:10742 /dev/sda2 start:10743 end:10946 Rebooted. No luck. fsck.ext4 can't find a valid superblock and I haven't had any luck finding a backup. Some things that may help: * MBR partition table. * All changes made with fdisk. * I found what looks like it may be a superblock at cylinder 6144, head 4, sector 16, with an offline disk editor but don't know how to tell fsck to use it. * Block size is 512 bytes. * Disk is a 90GB SSD. So, anyone know how I can return this file system to working order?
