A 6250 automatic read adjust identification (ID) detect error has
occurred. This problem may be caused by a bad tape or a dirty tape
path. Clean the tape path; see "Cleaning Procedure" on page 4-3.
Load a tape that is known to be good and attempt the operation again,
or run test 62 (with parameter A set to 11) to verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 62 (with parameter A set to 11) after each FRU is
exchanged to verify the repair.
A 6250 automatic read adjust identification (ID) verify error has
occurred. This problem may be caused by a bad tape or a dirty tape
path. Clean the tape path; see "Cleaning Procedure" on page 4-3.
Load a tape that is known to be good and attempt the operation again,
or run test 2 to verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 2 after each FRU is exchanged to verify the
repair.

Code
A bad tape mark was detected during a write (0059) or a write verify
(005A) operation. This problem may be caused by a bad tape or a
dirty tape path. Clean the tape path; see "Cleaning Procedure" on
page 4-3. Load a tape that is known to be good and attempt the oper-
ation again, or run test 62 (with parameter A set to 12) to verify the
repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 62 (with parameter A set to 12) after each FRU is
exchanged to verify the repair.
Part Number
A bad gap was detected during a write operation. This problem may
be caused by a bad tape or a dirty tape path. Clean the tape path; see
"Cleaning Procedure" on page 4-3. Load a tape that is known
to be
good and attempt the operation again, or run test 2 to verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 2 after each FRU is exchanged to verify the
repair.
A buffer parity error occurred during a write record operation.
Attempt the operation again or run test 12.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 12 after each FRU is exchanged to verify the
repair.

No data was detected during a write record verify operation. This
problem may be caused by a bad tape or a dirty tape path. Clean the
tape path; see "Cleaning Procedure" on page 4-3. Load a tape that is
known to be good and attempt the operation again, or run test 12 to
verify the repair.
If this reference code continues to occur, exchange the FRUs as
needed, and run test 12 after each FRU is exchanged to verify the
repair.
