Hope, again :-)
After three reboots of My Book World1 TimeMachine is running (after nearly 3 months it took the whole night to backup).
Mounting NAS via Finder takes more than one minute (when TimeMachine is running).
Mounting NAS via Finder takes about 30 seconds when TimeMachine is not running.
I’m on Lion and SnowLeoapard and 1.02.12
SnowLeopard Mac needs even more than 2 minutes to mount NAS with Finder (when TimeMachine is running)
and about 30 seconds when TM is not running.
It has been a few seconds on 1.02.06 !!!
I think, you WD should do some touching up on the firmware.
But I’m glad to use TimeMachine again
