A disk that I purchased new, and consolidated all my data to, actually ended up losing it's primary partition table and suffered from unknown other corruption and/or damage. Unfortunately, because real life has other demands and because I had a fairly recent backup and because I had undue faith in the drive, I did not have a current [[backups backup]] procedure in place to protect myself from data loss. So, I found myself investigating every known tool and technique for data recovery. The best tool I found was [http://www.gnu.org/software/ddrescue/ddrescue.html GNU ddrescue] ([http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html manual])
