Drive shouldn't matter. Refurbished are not 100% reliable, it is likely the hdd is bad. Look at the CD first. Make sure there are no scratches on it. If it looks good, download the data lifeguard cd if the drive did not come with one. There should be a DFT tool on it. Run it and fix any errors if finds any. Alternately, you can download the Ultimate Boot CD and use the HDD Diagnostic applications on it. Vivard I've found to be very universal but I believe there is a WD one on there too.
