SONY AIT-3Ex drive SDX-800V series Ver.1.0

6-91

MEDIUM ERROR

. Indicates that the current command or a previously acknowledged

write-type operation terminated with a non-recovered error condition that was probably
caused by a flaw in the medium, an error in the recorded data or the cleanliness of the

head. This sense key may also be returned if the drive is unable to distinguish between

a flaw in the medium and a specific hardware failure (sense key 4h). This condition is

also marked by the Valid bit being set, indicating that the information bytes contain

residue information.

00 02

END-OF-PARTITION / MEDIUM DETECTED

0C 00

WRITE ERROR – The Read-After-Write Retry limit was exceeded during Write.

Probably caused by a flaw in the media.

11 00

UNRECOVERED READ ERROR - C1, C2 & C3 Error Correction could not correct a

Read Error. Probably caused by a flaw in the media.

11 08

INCOMPLETE BLOCK READ - The drive could not read the AITFormat Group

containing the requested block. Could be caused by head clogging or media damage.

14 03

END-OF-DATA NOT FOUND – While Reading a AIT format tape, the drive

encountered blank (unformatted) media during a Read operation. This error could be

caused by serious head clogging.

15 02

POSITIONING ERROR DETECTED BY READ OF MEDIUM - Cannot find destination

Group during Space operation.

27 04

APPEND POSITION ERROR

30 00

INCOMPATIBLE MEDIUM INSTALLED - Format violation.
Possible that the Sub-Area cannot be read.

30 02

CANNOT READ MEDIUM, INCOMPATIBLE FORMAT - Format violation,

non-AIT-3Ex Format.

30 07

CLEANING FAILURE

31 00

MEDIUM FORMAT CORRUPTED - AIT format Group GIT, BAT, or Sub-Codes do not

match or are improper.

33 00

TAPE LENGTH ERROR - Attempting to select partition 1 on a single tape. Requested

partition size in MODE SELECT -
Medium Partitions Parameter page is too large (exceeds tape length) or too small (0<

requested partition size in frames < 2541).

3B 08

REPOSITION ERROR - Position lost during Read, Verify, Write, Space, Locate, Seek

or Select Partition operation.

50 00

WRITE APPEND ERROR - Cannot find the last frame of the Group and therefore,

cannot append.
