Useful information (Appendix)

This is part of the hard disk recovery documentation.


Here are all the tools that made an arguably irreplaceable contribution in the recovery:

Here are some additional links that I looked at, with more information:

For the record, here are the two external disks I have with their ext2 partitions’ Superblocks shown:

100GB disk, just one ext2 partition, starts at sector 63.

160GB disk, there is a 20GB FAT32 partition, and the second ext2 partition starts at sector 41945715. This is the partition whose backup superblocks are all off by +1KB (but are otherwise correct), and hence has an illegal formatting.

And here are the ddrescue log files, from the first run and the second run.

Back to the beginning.
