Hard Drive not detected!
I currently have an 80 GB sata hard drive and I bought an Hitachi 320 Gb sata drive to upgrade it with, but the laptop doesn't detect the drive, not even in the bios! It's brand new, and if I connect it using a USB adaptor, the drive shows up on my computer. The Bios has been updated to the current version. I'm at a loss, please help!
