Today, I deleted /usr/bin/ as well as a large portion of /usr/share/ by sudo tar tzf /mnt/card/data.tar.gz|sudo rm -r. In retrospect, I obviously shouldn't have done that. I'm quite stressed and annoyed that I have no recent backups, so I was hoping that there was some way to recover files from my flash. I'm running pdaXrom beta3 on a C3100 with the full-size root partition.
