Hey guys, back in August, I bought a 400 gig SATA hard drive from Western Digital, that it took me about a week to figure out (with some research @ WD, well hidden, I might add) was NOT compatible with Macs, for some reason. Had no problem returning it to Newegg, but it made me gun shy as far as ordering something else. I'm ready to try it again, but figured that I'd ask you guys for a recommendation. I need an internal, and it's for the Quad 2.5 Mac. Thanks in advance!
