Has anyone seen the news lately about used hard drives with confidential data on them?The Register: Missile data, medical records found on discarded hard disks
I was wondering if using a hard drive eraser program is enough. I am trying out a program that erases files by writing over them 7 times. I hope it is enough for almost any person that would get a hold of my hard drive after I have discarded them.
I have discarded two hard drives before and one of them worries me. The hard drive crashed, but I could still read most of the data on the drive. I was required by Dell to send it to them because they replaced it under warranty. I am willing to bet they tested the drive, confirmed it was bad, and tossed it in the trash. The other drive I am not so worried about because when it failed, it was part of a RAID 0, so it only contains half of the data in small stripes.
Right now, I have three hard drives that I am not using, 20GB, 40GB, and an 80GB. Since they have been boxed up for awhile, I am going to erase them now so that way I don't accidentally throw them away with confidential data on them.
