Query: Not good for G5 Mac!

Before buying any WD Raptor high performance hard drives for use in a Mac G5... search the WD website until you find the tech support article that says some are not compatible. I thought we were all past this sort of stupid problem, but apparently not. WD apparently held back on publicly admitting this for way too long.The Raptor is "enterprise class" and marketed as being built for heavy usage. And it does SEEM to work ok in a Mac dual G5 tower. But under heavy usage it locks up the OS really badly. (Like every other week, but sometimes goes 80 days). This cost us untold grief & thousands of dollars before figuring it out 13 months later. Adding a PCI SATA card fixed the problem. WD blames Apple, but Apple says they are at SATA spec. Whatever, it was a horrible combo until we added the basic (bootable) Sonnet pci sata card to drive the WD Raptor drives. Do your homework & beware.
