But that assumes that the firmware on the disk will do just that. Someone, Toshiba I think had problems with that on travelstar type disks in the past. You can't truly trust being able to talk to an entire disk these days. Well, maybe, if you have a test jig for it, or have documentation on some hardware strap to throw to get into some interesting mode. Complexity gives rise to all sorts of tools, and possibly, mischief. --STeve Andre'
