Notes:

The LOCATE command is not supported for tapes written in 8200

format and will result in Check Condition status. The sense key

will be set to Illegal Request (5h).

If the disconnect option is enabled, the CTS can disconnect from

the initiator while the LOCATE command is executing.

If a LOCATE command in the reverse direction is received after a

WRITE (0Ah) or WRITE FILEMARKS (10h) command, any

buffered data, filemarks, or setmarks (8500c format only) are

written to the tape before the locate operation is performed.

If an error occurs when the data in the buffer is being written, the

CTS returns Check Condition status and the locate operation is

not performed. The initiator should issue a REQUEST SENSE

(03h) command to determine the cause of the error.

If the CTS has the EEPROM image for directory support and the

CTS detects an EOD mark before the first filemark on tape, it

spaces over the EOD mark (at high speed) and up to 20 MBytes of

erase area until it finds the filemark it is seeking. For more

information about directory support, refer to Appendix B.

Note that if you are using an EXB-8505 with a tape that contains

two partitions (8500c format only), directory support is not

applicable. A directory created as described in Appendix B is not

supported on a dual-partition tape because the EXB-8505 will not

ignore an EOD mark before the first filemark. In addition, the

ADE bit (Always Detect EOD) in the LOCATE command has no

effect on a dual-partition tape.
