I'm having an issue with the installation of a Western Digital SATA II hard drive. BIOS recognizes it but Windows won't, and when I run Data Lifeguard Tools, it doesn't recognized the drive either. I think it's a RAID problem with Windows, but I've disabled RAID on BIOS. My motherboard is a Gigabyte GA-8I915P (915 chipset) with only SATA I ports. The WD site said that if you set the jumpers correctly, which I did, then the drive would revert back to SATA I speeds so as to work with my motherboard. I already have a 250GB Western Digital PATA hdd installed as my boot drive, and I'm trying to install 2 x 320GB Western Digital SATA II drives in addition. Any help would be appreciated.
Try going to control panel > administrative tools > computer managament > disk managament and format it there
No, Windows entirely doesn't recognize it, though BIOS does. There aren't any unknown listings either. update - I've solved the problem by uninstalling the old SATA RAID drivers and installing new ones, and messing with some BIOS settings. At first the two PATA optical drives that I have stopped working once the SATA drive began working, but I also reinstalled those drivers afterward and now it all works.
