I get your pain and Im with you now.
I have been fighting with 2 x MBWE II (6gb) on/off for a year now where it simply dies on me all the time when I transfere files.
Yesterday I got so sick and tired of the situation that I did the following :
* Turned off MioNet - but found out that it might not be turned off after all
* Then I followed the instruction here http://community.wdc.com/t5/Other-Network-Drives/Drive-Becomes-Un-Accessible-After-short-use-II/td-p/38659/highlight/true
Result : One got Bricked, but the other has run since last night non stop and I have succesfully transfered a file of 300 GB.
It takes forever because of the VERY slow transfer rate MBWE II has, but it acually seems to work … at least for one.
I also gave it a static IP both in the Router and MBWE as I read somewhere that it could help.
The 2 disks from the MBWE that got Bricked are now in a Synology and a NetGear NAS. Both hardware have never given be pain whatsoever. The empty MBWE plactic box now served as a trach can and a friendly “reminded” next time I feel the urge to buy WD 
it is stunning that WD gives the forum so little attention or are able to help users or support them in any way.
Thanks to those who did and I hope this has saved … at least 50% of my investment.
