Lock doesn't prevent format.
WOW... Piru got something wrong... :eek:
Lock DOES prevent you from Formatting a HD, just tried it a moment ago from both the CLI & the Workbench
Result, A requester telling you "Device In DHX: is write Protected" Format Failed...

I should point out that this was tried on OS 3.5, not sure about 3.0 or 3.1 as I don't have any partitions on those machines that I can risk testing it on...
