Illegal Media Type

When an illegal combination of medium type and drive is
detected, the Drive will terminate the WRITE FILEMARKS
command with CHECK CONDITION status. The Error Code will
be set to I
NCOMPATIBLE MEDIUM INSTALLED
written.
See the WRITE
media/format combinations.
32.5.3.

Illegal Append Tape Format

When appending data on a pre-recorded tape the only
legal tape format is the format found on the tape. If
the format set by the MODE SELECT command is not equal
to the tape format, the Drive will terminate the WRITE
FILEMARKS command with CHECK CONDITION status. The Error
Code will be set
tapemarks will be written.
32.5.4.

Logical Early Warning

If logical early warning (LEW) tape marker is reached
during the execution of a WRITE FILEMARKS command, the
Drive will respond as described below:
The Drive will attempt to write all buffered
tapemarks. The WRITE FILEMARKS command will then be
terminated with CHECK CONDITION. If all tapemarks and
data in the buffer were successfully written to the
tape, the Error Code will be set to E
/
PARTITION MEDIUM DETECTED ON WRITE
VADD bits will be set to one. The Information Bytes
will be set to zero.
The Drive will force unbuffered mode (regardless the
state of the BM bit in the MODE SELECT/SENSE
Parameter List).
If a read type command (READ, LOCATE, SPACE or
VERIFY), has brought the tape past the LEW marker and
an Append Operation is attempted, then the Drive will
terminate the first WRITE FILEMARKS command
immediately with CHECK CONDITION. No tapemarks will
be written. The Error Code will be set to E
/
PARTITION MEDIUM DETECTED ON WRITE
VADD bits will be set to one. The Information Bytes
in the sense data list will be set equal to the
requested transfer length.
The Drive will force unbuffered mode (regardless the
state of the BM bit in the MODE SELECT/SENSE
Parameter List).
If another WRITE FILEMARKS command is received by the
Drive while the tape is positioned after LEW (but
before end of partition), the Drive will transfer and
write all requested data if possible. The WRITE FILE-
MARKS command will then be terminated with CHECK
CONDITION (this will be true even if the requested
Number of Tapemarks is zero). If all tapemarks were
successfully written to the tape the Error Code will
be set to E -
ND
EOM and VADD bits will be set to one. The Information
Bytes will be set to zero.
