I recently bought a 500gb WD Blue HDD at a garage sale. I have no idea if it works or not, but it appears to be in good condition on the outside. With my pc I just bought, I realized it has the exact same hdd in it. What is the best way to test this hard drive? I thought the easiest way would to go on ebay and buy a 9" SATA Cable (http://www.ebay.com/itm/9-SATA-SERIAL-ATA-HDD-HARD-DRIVE-OPTICAL-DATA-STRAIGHT-TO-ANGLE-RED-CABLE-USA-/291760007343?hash=item43ee4068af:g:5QIAAOSwFNZWzL9t). Then, just boot up the system normally, but with two hard drives plugged in. There is another mounting spot below the current hard drive, an empty plug on the sata power cable that plugs into all drives, and two empty sata data ports on the motherboard. So, would this be an effective way of testing this HDD? I think someone mentioned that I could get a virus just by plugging it in and looking if it shows up in my drives list. If this method is "unsafe" what would be a better way to test this drive? All help is very much appreciated! THANKS! -Ethan
