Additional Sense Code & Qualifier: Specifies detailed information related to the
additional Sense Code. If the error or exception condition is reportable by the device
the value returned will be as specified. If the condition is not reportable by the device,
a value of 00h is used.

Field Replaceable Unit: The value of this field will be 0, indicating that no specific
mechanism or unit has been identified to fail or that the data is not available. There
are no FRUs in the drive.

Data Error Counter: For write operations, this is the number of blocks since the
start of the current write operation re-written because they were detected to be in
error by the READ-WHILE-WRITE check. For read operations, this is the number of
blocks recovered by ECC or read-retry since the tape was last at BOT.

error by the READ-WHILE-WRITE check. For read operations, this is the number of
blocks recovered by ECC or read-retry since the tape was last at BOT.
Buffer Overrun / Under-run Counter: For write operations, this is the number of
times that the under-run logic was forced to rewrite a data block in and under-run
condition. (An under-run can occur without tape reposition.) For read operations, this
is the number of times a reposition cycle was required due to buffer overrun.
