Sony SDX-1100V/R Device VENDOR/SERIAL Number attribute format Bit Byte, Vendor Identification

12.APPENDIX E: Medium Auxiliary Memory Attribute

0006h FORMATTED DENSITY CODE: This attribute value provides information about the tape format for the user.

0007h INITIALIZATION COUNT: This attribute value indicates the number of times that a drive has logically formatted the medium. This figure is cumulative over the life of the medium and will never be reset.

020Ah, 020Bh, 020Ch, 020Dh DEVICE MAKE/SERIAL NUMBER AT LAST LOAD, DEVICE MAKE/SERIAL NUMBERAT LOAD – 1, DEVICE MAKE/SERIAL NUMBER AT LOAD – 2 AND DEVICE MAKE/SERIAL

NUMBER AT LOAD –3:These attribute values give a rolling history of the last four drives in which the medium has been loaded. The format of the attributes is shown in Table 12-7

VENDOR IDENTIFICATION: This field will be the same value returned in the standard INQUIRY data.

PRODUCT SERIAL NUMBER: This field contains a vendor unique serial number. If the product serial number is not available, the PRODUCT SERIAL NUMBER field will contain ASCII spaces (20h).

0220h TOTAL MBYTES WRITTEN IN MEDIUM LIFE and 0221h TOTAL MBYTES READ IN MEDIUM LIFE:

These attribute values indicate the total number of data bytes that are transferred to or from the medium surface, after any data compression has been applied, over the entire medium life. These values are cumulative and will never be reset. These values are expressed in increments of 1,048,576 bytes (i.e. a value of one means 1,048,576 bytes, two means 2, 097,152 bytes, etc).

0222h TOTAL MBYTES WRITTEN IN CURRENT/LAST LOAD AND 0223h TOTAL MBYTES READ IN CURRENT/LAST LOAD: These attribute values indicate the total number of data bytes that are transferred to or from the medium surface, after any data compression has been applied, during the current load if the medium is currently loaded, or the last load if the medium is currently unloaded. The drive should reset these attributes to zero when the medium is loaded. These values are expressed in increments of 1,048,576 bytes

(I.e. a value of one means 1,048,576 bytes, two means 2,097,152 bytes, etc).

0340h MEDIUM USAGE HISTORY: This attribute value provides statistical counters (Table 12-8) for the entire medium. The value in each field is the sum for all partitions. If a field is not used, it should be set to zero.
