I bought a Dell desktop five weeks ago and it crashed already (before the external hard drive that I had just purchased online a few days before arrived). The tech guy came out and replaced both the motherboard and the hard drive. I tried to access my old files using an enclosure, but no luck...the device can not detect the hard drive. Seems that my files are either gone or too expensive to recover. In any event, my complaint now is that Dell demands that I return the defective hard drive to them or pay $150. I'm concerned that with their better equipment they might be able get to my files (sensitive data like tax forms, etc) if they wanted to. This seems like extortion: either I pay them a lot of money or put my data at risk. What do others think? Any suggestions for how I could wipe the drive clean without doing physical damage to it? I will never buy anything from Dell ever again. Any help would be appreciated.
