Hi there, Someone gave me a Dishnetwork pvr. it had a WD 500 gig sata drive so i thought it would go great in my pc. the bios detects it as the fourth master but wont allow my pc to boot from my main drive. I get a disk error message and the pc hangs. Is the drive shot or does it need to be formatted? If so, how do I format it if i cant boot? if i disconnect the drive the pc boots normally but it wont detect the drivafter i plug it in like a usb. I never checked the dvr and i threw away the IRD after i pulled the drive.
