Enhancements
Previous firmware versions (VUA2 and VU98) did not support Revision B hardware. If you tried to
load earlier versions onto Revision B hardware, the drive would reject it as being invalid.
This new firmware upgrade has all the same features as previous versions plus the fixes detailed
in the next section and the new feature of supporting Revision B hardware.

Fixes
• Fixed a Write Timeout issue which occurred when using DAT160 media with data compression
OFF.
• Fixed a USB protocol issue whereby inserting a USB device onto the same USB root hub whilst
the DAT320 drive is operating caused the drive to hang. This issue affected only Windows
2008 and later systems.
