The level of paranoia is the key question. If this were my own personal data, I would do one of the steps John and Scott mention, and move on. If this were my employer's data, (and therefore, perhaps, many many people's data) I would, and we do, spare no expense to make sure the disks are unreadable.

Realistically, if you have a couple of holes in the platters, once the drive spins up and the head moves across the hole, it's going to bounce and the hit the platter, causing all kinds of problems. Again, what level of paranoia are you going to use here? Yes, the NSA/CIA/FBI might be able to pull some data off a platter with holes in it, but at what cost? In 99.999% of all cases, just doing either of these two steps will effectively destroy the drive and any data on them. If you need certainty, then shredding or a sledge hammer (a warped platter isn't going to be ready by anyone) will do the trick to any degree. >From the sound of the original request, I suspect that the drives were already dead and not responding to accesses, but had potentially some risk of data being pulled off them. In that case, just going the next step of disassembling them or drilling holes would make it effectively impossible to recover data from them. Is that a 100% guarrenttee? Of course not.
