Error Description
766Bh Recovery process is using a secondary head set to perform a sensor calibration operation.
766Ch Recovery process is using a secondary head set to perform an azimuth calibration operation.
766Dh Servo calibration cannot be done now because it is too close to BOT.
766Eh Timed out waiting for half moon to approach head during a thread.
766Fh Timed out waiting for half moon to approach head during an unthread.
7670h Timed out waiting for half moon to pass head during a thread.
7671h Timed out waiting for half moon to pass head during an unthread.
7672h Timed out waiting for half moon to enter guide during an unthread.
7673h Servo timing reference mismatch during timing reference calibration
Set position and speed operation missed the target objectives by too much, probably due to
7674h
DSP retries.
Timed out waiting for the grabber to rotate enough to deactivate the tape lifter and lower
7675h
the tape onto the head
Cartridge Memory read after threading; mechanism parameters cannot be updated at this
7676h
time.
7677h Mechanism sensors not in the expected state after a load command.
7678h Mechanism sensors not in the expected state after an unload command.
7679h Mechanism sensors not in the expected state after a grab command.
767Ah Mechanism sensors not in the expected state after an ungrab command.
767Bh Deslacking process did not complete, probably due to the back reel motor failing to rotate.
FRM tension ramp process did not complete, probably due to excessive tape slippage in the
767Ch
cartridge.
767Dh FRM rotation was unexpectedly detected while ungrabbing the cartridge leader pin.
The calculated LPOS media manufacturers string checksum does not match what was read
767Eh
from the tape.
767Fh The LP sensor was asserted before loading, possibly because of a stuck or faulty sensor
7680h The DSP was commanded to re-lock onto servo code. (This is a recovery algorithm.)
7681h A retry was necessary on a DSP seek command. (This is a recovery algorithm.)
7682h A retry was necessary on a DSP VI-sensor cal command. (This is a recovery algorithm.)
7683h A retry was necessary on a DSP azimuth cal command. (This is a recovery algorithm.)
7684h A retry was necessary on a DSP command to learn the VI-offset. (This is a recovery algorithm.)
7685h Unable to thread. An ungrab/regrab/rethread recovery process will now be attempted.
