by non-HP drives
• Error rate counters are now cleared on a load rather than being cumulative after power-on
• The number of retries is now extended if the Cartridge Memory cannot be read
Fixes
• Fixed a rare issue where a Write attribute command could cause datasets to be written beyond
the End of Wrap (EOW) turnaround point
• Differences are no longer observed between the power-on times reported in different Library &
Tape Tools (L&TT) logs and the drive logs
