0000h REMAINING CAPCACITY IN PARTITION and 0001h MAXIMUM CAPACITY IN PARTITION: Are Native capacities assuming no data compression for the specified medium partition. 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).

0002h TAPEALERT FLAGS provides a means of reporting the state of the Tape Alert flags for the previous load of the medium. Each Tape Alert flag occupies one bit (Flag 1 = MSB Byte 1; Flag 64 = LSB, Byte 8). The bits specify all the Tape Alert flags that were set during the previous load. (I.e. the bits are “sticky” for the load).

003h LOAD COUNT: Indicates how many times this medium has been fully loaded. This attribute should not be reset by any action of the device server.

0004h MAM SPACE REMAINING: Indicates the space currently free in the medium auxiliary memory. The total medium auxiliary memory capacity is reported in the MAM CAPACITY attribute.

0005h ASSIGNING ORGANISATION field data identifies the organization responsible for the specifications defining the values in the formatted DENSITY CODE attribute. The ASSIGNING ORGANIZATION field should contain a value listed in the vendor identification list. The use of specific vendor identification, other than the one associated with the device is allowed.

Note: It is intended that this field provide a unique vendor identification of the FORMATTED DENSITY CODE attribute. In the absence of a formal registration procedure, T10 maintains a list of known vendor identification codes in use. Vendors are requested to voluntarily submit their identification codes to T10 to prevent duplication of codes.

0006h FORMATTED DENSITY CODE provides information about the tape format for the user.
