FSC Description ERP Number Cause
67 The drive cannot program one of the memory areas. 12 D = 100%
69
Cyclic Redundancy Check (CRC) in the LOAD IMAGE
operation was not correct.
8,6 T = 100%
6D The READ BUFFER command failed. 12 D = 100%
71
The tape is at an illegal position to format the
partition.
2
D = 50%
O = 50%
72 The partitions are too big for the tape. 2 O = 100%
74 The partition format of the tape failed. 8,6 T = 100%
75 The partition format was aborted. 8,6
D = 5%
O = 90%
S = 5%
79 The drive failed to position the tape to a new partition. 8,6 T = 100%
7A The partition switch operation was aborted. 11
D = 5%
O = 90%
S = 5%
8C A controller firmware logic error occurred. 12 D = 100%
8D The software detected a hardware problem. 12 D = 100%
93 A PEOP was detected. 10 A = 100%
94
The drive failed to perform the WRITE SETMARK
operation.
6 T = 100%
95
A WRITE failure occurred after the retry limit was
exceeded.
8,6
D = 30%

96
A WFM failure occurred after the retry limit was
exceeded.
8,6
D = 30%
T = 70%
97
A WRITE EOD failure occurred after the retry limit
was exceeded.
8,6
D = 30%
T = 70%
98
The Buffer Record Table (BRT), which is a list of block
addresses, contains an incorrect value.
12 D = 100%
99 The buffer is empty, which caused a fill error. 12 D = 100%
9A
A timeout occurred during the search function because
the data interpreter did not encounter the required
text.
12 D = 100%
9B
The read-back-check operation detected a different
block type from what was written (old data is not
being fully overwritten).
8,6
D = 50%
T = 50%
9C
A formatter interrupt timeout occurred during a
WRITE operation.
12 D = 100%
9D
A permanent write error was encountered, causing the
write recovery to fail.
