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.
