Thanks for any help in advanced. I've searched the WD, EVGA, and Windows forums along with the standard Google searches and haven't been able to figure out my problem.
I recently had my older 150GB Raptor drive fail and RMA'd it and got the WD1500HLFS as a replacement. I installed it into my computer, disconnected my other two 1TB WD Caviar Black drives, and attempted to reinstall Windows 7 64-bit onto the new VelociRaptor drive. The Windows 7 installation doesn't recognize the new drive though. I tried different SATA ports on my motherboard (which is an EVGA 780i SLI 132-CK-NF78 motherboard running the latest P10 BIOS). I also reconnected my two 1TB drives and the Windows 7 installation detects those without an issue. I also tried loading the SATA IDE drivers I downloaded from EVGA's website during the install, but it still won't detect the new 150GB drive.
After that, I ran the DLGDIAG 5.04f on the drive (quick and extended tests) and it found no issues with the drive. I booted up Windows on a separate 500GB hard drive I had with the new VelociRaptor drive connected and it showed the drive without an issue. I also tried formatting the new drive within Windows, but the WIndows 7 installation still won't detect the new hard drive.
The drive is standalone (no RAID), and I never had this issue before with the older 150GB Raptor drive (reinstalled Windows several times with the old drive). So needless to say, I'm at a loss. Has anyone else ran into this issue or have any further suggestions?
