The total number of data bytes that are transferred to or from the tape surface
(after any data compression has been applied) over the entire tape life. These
figures are cumulative and will never be reset.
These are similar to the attributes above but apply to the current load (if the tape is
currently loaded) or the last load (if the tape is currently unloaded). The device
server should reset these attributes to zero when the tape is loaded.

be set to zero. The format is as follows:
