New Firmware Version 1.02.12 for the My Book World I & II (10/19/11)

I am also experiencing EXTREME slowdowns even using Finder. On my MacBook Pro (running Lion) the logon to mount the drive used to take <1 second (pre 1.02.12 update), now it takes 30+ seconds to mount. Open a folder = another minute or longer just to view the directory. Good news is that my login under Lion seems to work, but the drive performance is basically unusable at this point.
