How hard is it to format a drive before selling it? I know data can be recovered easily with simple utilities (done it myself many times), but just formatting it is enough to discourage 99.9% of would-be information thieves. Or use one of the many available freeware data-wipe utils. Or even download a utility from the manufacturer's website--most of these have the ability to write all 0s to the drive. Again, are people really that ignorant?
