+Remember wiping the hard drive will take some time to complete, so you'll want to make sure you have the computer on the testing shelf or in a location you can leave it for a bit. Be sure to let your instructor know the status of the system before the end of the shift.
 Please follow the steps below to wipe a hard drive.  If you come across problems, such as ''the system won't boot from CD'', you can refer to [[MacBuild Tips 'n Tricks]] for troubleshooting.

	Mac hard drives are wiped while still inside the system. This is because Macs take forever to disassemble. Currently Mac hard drives are wiped using the tools available during the network installation. Details are contained in the MacBuild checklists. If you should need to wipe a hard drive using a CD rather than the network you can use the instructions detailed below.		Mac hard drives are wiped while still inside the system.
