[QUOTE="immdb, post: 44453, member: 1238"] The "Zero All Data" option is a low level security technique. It won't make the drive any more useable than just doing an erase. By setting all of the bits to zero (zero all data), I guess that it would let you know if the drive has a spot that it can't write to, but it can't do anything about it. If a sector is bad on the drive, a program like Drive 10 can map out that sector so that the operating system doesn't see it. You would then be able to use the drive. [/QUOTE]
