... tak Adaptec se vyjádřil:

Hello from Adaptec,

We know about an issue with WD2502ABYS, WD3202ABYS and WD5002ABYS. You must disable SSC (Spread Spectrum Clocking) on the drives. Please get with Western Digital and ask for the utility that allows to disable SSC. Please note that jumpering the drive for SSC disabled does not work.

Make sure that the latest firmware/BIOS is installed on the RAID Controller.
Od WD zatím nic nepřišlo. Na webu mají jenom popis nastavení pomocí JUMPERů, tak ještě vyčkávám.
