Recently I had a hard drive failure that pushed me into getting a little NAS device that I could back up to S3 easily. After consolidating a lot of data to the NAS I was left with a few old hard drives that I needed to do something with as well as some existing hard drives that I've collected over the years. Some of the drives I have are from family members that I have recycled computers for but kept the hard drives out of fear that personal data might still be on them. At the same time this was happening I read an article claiming that a single drive wipe protects data.
