Tandberg Data
The Threshold Met Criteria (TMC) field is set to 0.
The List Parameters (LP) bit is set to 0 to indicate
that the parameter is a data counter.
This field is set to 1 to indicate that the parameter
field is one byte long.
Bit 0 of this byte is set to 0 when the flag is FALSE.
Bit 0 of this byte is set to 1 when the flag is TRUE.
Bit 1...7 are all reserved and are set to 0. Unsupported
TapeAlert flags are all set to FALSE.
The following TapeAlert flags are supported:

Cause
This flag is set to 1 for any unrecoverable
read/write/positioning error, and is internally cleared when the
media is ejected. (This flag is set as an explanation of the error
in conjunction with one of the recovery action flags 4,5 or 6.)
This flag is set to 1 when the Media Management algorithm
detects a medium with severely degraded performance. The
drive will monitor the media performance and maintain a media
performance history log in the media header. The algorithm is
executed each time the media header is updated (i.e. after a
REWIND or LOAD/UNLOAD command). This flag is also set to
1 for any unrecoverable read/write/positioning error that is due
to faulty media. The flag is internally cleared when the media is
ejected.
This flag is set to 1 for an unrecoverable read error where the
diagnosis is uncertain and could either be faulty media or
faulty drive hardware. The flag is internally cleared when the
media is ejected.
This flag is set to 1 for an unrecoverable write error where the
diagnosis is uncertain and could either be faulty media or
faulty drive hardware. The flag is internally cleared when the
media is ejected.
This flag is set to 1 when the tape drive detects that the head
needs cleaning. The flag is internally cleared after a successful
cleaning operation.
This flag is set to 1 when the drive detects that an inserted
cleaning cartridge has been exhausted. The flag is internally
cleared after a successful cleaning operation with a new
cleaning cartridge.
This flag is set to 1 when the drive fails in it's internal Power
On Selftest (POST). The flag is only cleared when the drive
power is turned off.
