well, you know i wasn't just going to give up on this thing LOL
today i decided to get to the bottom of it. this time however, i have moved all my email and applications over to my spare PC so that i can still work while i figure this one out.
so i replaced the motherboard this afternoon. by "replaced" i mean i went back to the Albatron PX865PEC Pro motherboard. this time i unplugged everything and i just had the bare essentials to boot the system with... same problem. the 36GB raptor is just not recognized by this board.
mind you, it's the same chipset and supposedly the same sata controller as the Intel D865GBF motherboard (where the drive works just fine), so i did a bit of research and i could only find 1 website with info on this issue:
http://www.driverheaven.net/showthread.php?t=118201the link describes the exact same problem that i'm having. it seems to be related to WD SATA hard drives combined with the ICH5 intel chipset, although, as i have just proven, in my case it seems to be BIOS related and unfortunately Albatron don't have any updated BIOS for my motherboard. i'm already running the latest BIOS.
so now that i know that this is a known issue, i'm planning to get a SATA PCI card and boot the raptor off it. hopefully that will work.
