My wife was inattentive to backups and when her computer suddenly died(literally, it went up in smoke) our IT guys couldn’t access the disk to copy files to another machine — the electronics were fried. The only option they could suggest was disk doctors. DD took the disk apart and basically built a new disk around the old platter, and managed to recover pretty much everything my wife cared about — her professional emails and contact information, her emails from her mom(who had passed away, so those had a lot of personal value to her). It wasn’t cheap, and in fact we needed two«rounds» of recovery to find all the files we needed — be careful to check the list they supply and confirm that it really has all your critical data, because in our case, there were files not on that list that we needed. Then I also needed to purchase a tool for repairing corrupted Microsoft Outlook email files, from a company named Stellar Phoenix. But with that, and the disk doctors guys, I’m definitely a fan and my wife is overjoyed to have her stuff back. Now she’ll be better about backups…
