I have always wondered about this, why not just do a rm -rf * on the drive, then put one big file on it (some divx movie or such), and copy it over and over under different names until the drive space gets exhausted completely? This can easily be scripted, and I believe it would work as fast as possible for a drive of given capacity. The idea is that drive has a limited capacity overall, so if you do this a couple of times, there will be no way of recovering any sensitive previously deleted data. A drive can remember only so many bits, eventually all storage space will get exhausted/overwritten... Or am I missing something?
