Disk Test/Clean

This is a two hour test that should be performed only on a disk that
contains bad data and is therefore unusable.
This test destroys all data on the disk by doing a multi-pass write/
read on every block of the disk. Bad blocks are flagged and removed
from use. If over 2000 bad blocks are found, the test stops and the
display indicates the disk must be replaced.
A message describing test progress is displayed during the test.
1. Enter Diagnostics mode.
2. Select [DEVICE TESTS].
3. Select [Disk Test/Clean].
4. Select [CONTINUE] to start the test, or [CANCEL] to return to
Diagnostics mode main menu.
5. Select [CANCEL] to interrupt the test.
