TOTAL MBYTES WRITTEN IN CURRENT/LAST LOAD and

TOTAL MBYTES READ IN CURRENT/LAST LOAD:

Indicates the total

number of data bytes 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 resets these attributes to 0 when the medium is

loaded.

These values are expressed in increments of 1,048,576 bytes; that is, a

value of 1 means 1,048,576 bytes, 2 means 2,097,152 bytes, and so forth.

MEDIUM USAGE HISTORY: Provides statistics (see figure 141) for the

entire medium. If a field is not used, it is set to 0.
