I have an external drive containing a lot of valuable data, and it endured a partial format to ext3. Only about 10% of the drive was formatted, and superblocks were not written. Original format of the drive was ext3, and it was partially formatted to ext2 with mke2fs. I downloaded e2retrieve to fix it, and after running for a few hours, it gives me the following:

Code:

Superblock #1 has been choose.

Initialize bitmaps from superblock informations :
Done
Initialize memory bitmaps from disk bitmaps :
Done
nb dir stubs ok = 0, ko = 10611 / 18640
Marking blocks...
Segmentation fault


I have more than enough disk space to do the recovery, and I'm reading straight from the target drive. I would really like to recover this data with as many directory structures / filenames correct as possible, so any hints as to how I can use e2retrieve properly or pointers toward another utility are very welcome.
