Fixed Disk Drive Backup (Tape)
The Fixed Disk Drive Backup (Tape) test verifies
the tape backup, the fixed disk drive control-
ler, the tape host adapter, and associated cables.
Depending on the computer configuration, the
Fixed Disk Drive Backup Menu may appear.
This menu allows you to run the following tests
selectively:
□ Format Fixed Disk Drive Backup Cartridge
(for diagnostic use only)
□ Fixed Disk Drive Backup Device
□ Fixed Disk Drive Backup Media
During each of these tests, the screen displays
each track and block as it is checked. The follow-
ing paragraphs describe these selections.
Format Fixed Disk Drive Backup Cartridge
(for diagnostic use only)
This selection formats a fixed disk drive backup
tape cartridge for use during diagnostic testing.
This selection tests the format and servo write
circuitry.
CAUTION
This test will destroy stored data. When
prompted, be sure to insert a blank tape
cartridge to avoid losing data.
The test goes through two stages of formatting:
physical formatting and logical formatting. Each
stage requires an extended period of time.
CAUTION
Do not interrupt the physical formatting
process in any way. An interruption can
destroy the servo information on the tape
cartridge requiring erasure before refor-
matting.
