Disk Test/Clean
This is a 90 minute 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 read/write
on every block of the disk. Bad blocks are flagged and removed from
use. If over 2,000 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.
