According to this thread:
http://community.wdc.com/t5/Other-Internal-Drives/WD2002FYPS-firmware/td-p/63330
the WD2002FYPS-02W3B0 models seem to be really bad for RAID systems.

The former models with the most recent firmware seem to work somehow:
Model: WD2002FYPS-01U1B1
FW:    04.05G05

Seems I have to exchange the drives to get a working array.

I got an reply from Western Digital that all my disks have the most recent
firmware available.

I wonder why I had the very same problem with Seagate Barracuda ES 320GB
drives!

Thanks again and sunny greatings to brazil.
Lars
