0000h REMAINING CAPCACITY IN PARTITION and 0001h MAXIMUM CAPACITY IN PARTITION: These
attribute values 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: This attribute value 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: This attribute value indicates how many times this medium has been fully loaded. This
attribute should not be reset by any action of the drive.
0004h MAM SPACE REMAINING: This attribute value 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: This attribute value identifies the organization responsible for the
specifications defining the values in the formatted DENSITY CODE attribute. The ASSIGNING ORGANIZATION
field will 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.
