Been there, wasted $$$, now I only buy one type of validated, extremely reliable enterprise-grade disk from Hitachi. :-) Seagate and Western Digital both have have serious Q/C problems recently with their drives, and WD especially makes drives that will fail or function very poorly in enterprise hardware, all in the interest of being "green". Ugh.
Would you post a link to the model number you like?
Thanks! :)
