Retry Log Data Format

NOTE This log is ONLY supported on the 40fx, 80ex, 125ex and 220mx models.

This table can be accessed via the Log Sense Command (4DH),

Table 3-45 on page 3-47, with page code 39H.

Each retry algorithm code byte triggers a specific retry algorithm on the

preceding move command. The byte order is the same order in which the

retry algorithms were run.

The last four bytes may be organized as two 16 bit words. The first word

is the cumulative number of Inline Retries (since the jukebox was built),

and the second word is the cumulative number of Major Retries (since

the jukebox was built). Inline Retries are attempts to move again from

the error position. Major Retries are attempts to move again after a Find

Home command has re-zeroed the unit.
