1. DATA READ: There is no restriction when reading data in WORM mode.
2. DATA WRITE: Any attempt to overwrite existing data will be rejected with a Check Condition status and
sense data.
● Write Projected Error: 07-27-00-07 (Sense Key, ASC, ASCQ, Run-time-error)
● Append Position Error: 03-27-04-f7
The AIT WORM drive will allow write operations when:
(1) Append Write Operation is allowed only at End-Of-Data (EOD) area. Prior to an Append Write Operation,
several commands can be used to position the drive at EOD area:
● Space to EOD (space code 3)
● Space to last record (could be a block, File-mark, Set-mark)
● Locate to last block
● Read until EOD
For example:
No

Mode Select (Page 31h)
Mode Select (Page 11h)
