I was over at a good friends house this last weekend, he and his wife had a BBQ and invited me and some of his other friends over. There was one guy there that I had never met and after talking to him for a little bit I find out that he works for a computer forensics company and actually does recovery work. He talked for a bit about some of the interesting things he's come across while recovering data from drives. At one point I asked him if his company has every recovered data from a wiped drive and he told me that they can recover data no matter how a HDD is wiped. Said that physical destruction is the only way to keep data from being recovered. I told him my method for wiping data before selling/donating any personal computer and he claimed that his company could retrieve most if not all data even after a through wipe. My method for wiping any personal PC before selling/donating is as follows: first I run parted magics internal secure erase command "enhanced" method and secondly after that finishes I run dban 2.2.6 dod 7-pass. HDD's have no bad sectors and do not show any errors while running dban. I was under the impression after doing quite a bit of research on wiping drives that even one pass from dban or similar programs would make data on a drive unrecoverable. Was this guy telling me the truth or just full of crapola?
