Fixes
New functionality
File Mark (FM) interpolation unreliable with unevenly distributed FMs
Previously, when spacing forwards on a tape which has >100 FM that are unevenly spread over a
half wrap the drive will not try to work out where to start the search from but will now start searching
from the current position.
Add event log entry for power on reason
The event log will now extract and interpret the reason for the power on event (i.e. FW upgrade,
assert reset, power on, etc).
Drive hangs
TFT 85 Hang caused by explicit signal consumption
Previously, under certain timing conditions it is possible that a read could hang due to the FW explicitly
consuming an important signal. This has been fixed in this release.
