Aside from the info Andreas provided, you could try e2salvage. It is designed to go through the disk block by block and reconstruct the directory structures from that. It's advisable (always do that before trying disaster recovery) to make an image backup of your drive first though (try dd -if /dev/hdX -of <file or device name>) Note that when -of is a device, the device will be overwritten with the -if device data. Also realize this is a bit-for-bit copy, so you'll need *at least* the same amount of free space as the *total amount* of bytes the old device has... http://project.terminus.sk/e2salvage/ Oh, another thought: I assume you are sure the drive was not part of a RAID set?
