Today I bought a Western digital caviar blue 500gb hard drive at a garage sale for a coupler of bucks. It appears to be in excellent condition, but the back cover is missing (side without all of the internals). The only PC I have is an old (10yr) prebuilt Dell. I assume the power supply doesn't have a SATA power I could hook it up to (probably just enough connectors for what the system needs, right?). If I removed the current HDD, which I don't really want to do, It wouldn't have an OS. Unless you could test HDD in the BIOS? Is there any other way to test this HDD? Thanks!
