New functionality
New functionality has been added to increase the drive's robustness to variations in media. This
will increase load time.
Enhancements
0x3350 errors will no longer be logged to the fault log if they require no corrective action.
Real Time Clock calculations are more accurate because they use 64-bit code that the hardware
supports.
Error rate counters are now cleared on a load rather than being cumulative since power-on.
There are now extended retries if the Cartridge Memory cannot be read.
Fixes
A performance issue spacing with a particular pattern of records and filemarks has been fixed.
A poor read performance issue that had been experienced when reading through filemarks on
fast hosts has been fixed.
The use of adjacent channel information during Spacing/Locating has been enabled to prevent
issues with spacing and locating errors 0x5090/0x5092.
