7.3 Exceptions and Error Conditions

The following exceptions and error conditions can occur with the

LOCATE command.

EOD Detected

If the CTS detects the end-of-data (EOD) mark during the locate

operation, it returns Check Condition status. The REQUEST SENSE

data is set as follows:

Valid 1

Sense Key Blank Check (8h)

Information

bytes

Indicate the difference between the requested logical

position and the actual logical position.

ASC 00h

ASCQ 05h

FSC 33h

When the LOCATE command terminates, the logical tape position is

after the last recorded data block, filemark, or setmark (8500c format

only).

Note: If the CTS has the EEPROM image for directory support (and

the tape contains only one partition), you can issue a LOCATE

command with the ADE bit set to 0 to move from the

directory to the data area of the tape. The CTS spaces over the

first EOD mark (as long as it is located before the first

filemark) and does not return Check Condition status.

However, when the CTS detects the second EOD mark at the

end of data, it returns Check Condition status with the sense

key set to Blank Check (8h).
