Byte 20, Bits 5 - WP (Write Protect) The data cartridge is write
protected.
Byte 20, Bit 4 - FMKE (Filemark Error) A write error occurred when
the CTS was attempting to write a filemark.
Byte 20, Bit 3 - URE (Under Run Error) A hardware data formatter
underrun error occurred. (Byte 20, bit 0, is also set to 1.)
Byte 20, Bit 2 - WE1 (Write Error 1) The maximum number of
rewrites was attempted. Media error.
Byte 20, Bit 1 - SSE (Servo System Error) A catastrophic hardware
error occurred. The servo system detected an error.
Byte 20, Bit 0 - FE (Formatter Error) A catastrophic hardware error
occurred. The data formatter detected an error.
Byte 21, Bit 7 - RSVD This bit is reserved.
Byte 21, Bit 6 - UCLN A cleaning cartridge was loaded but the
cleaning tape was used up, so a successful cleaning was not
performed. This bit is reset to 0 after a successful cleaning is
performed or the CTS is reset.
Byte 21, Bit 5 - RRR (Reverse Retries Required) The CTS was
forced to invoke retries in order to move the tape properly. This
bit is reset to 0 when a new tape is loaded.
Byte 21, Bit 4 - CLND The CTS has been cleaned. This bit is reset
to 0 when the next REQUEST SENSE command is received.
Byte 21, Bit 3 - CLN The CTS needs to be cleaned. This bit is reset
to 0 when a successful cleaning cycle is performed.
Byte 21, Bit 2 - PEOT (Physical End of Tape) The data cartridge is
positioned at PEOT.
Byte 21, Bit 1 - WSEB (Write Splice Error) A write splice error
occurred. The CTS encountered blank tape when it was
attempting a write splice operation. This is a Hardware Error.
Byte 21, Bit 0 - WSEO (Write Splice Error) A write splice error
occurred. The CTS passed the splice position when it was
attempting a write splice operation. This is a Hardware Error.
