ERROR DISPLAY
MEANING
POSITN.FAULT: 1
The tape position was too far ahead of BOT during a write-from-BOT operation.
POSITN.FAULT: 2
After completing the automatic write current calibration operation, the tape
position is too far from BOT. This error can only occur during a write-from-BOT
operation.
POSITN.FAULT: 3
A tape positioning error was detected while verifying the ID burst during a write-
from-BOT operation.
POSITN.FAULT: 4
The ID burst has been verified, but BOT was not sensed during a write-from-BOT
operation.
POSITN.FAULT: 5
BOT was not sensed during the initial forward motion during a write-from-BOT
operation.
POSITN.FAULT: 6
BOT was not sensed within 30-inches while reading the ID burst.
