puntoMX, Absolutely perfect mate, Thank you very much for taking the time to help me One more question if i may, the Samsung HD501LJ 500gb sata i have fitted is only 3 weeks old and started giving me windows write errors(this is why i bought the Western Digital to back up), so i ran CMD and ran chkdsk /r, since then i have had no write errors. In your opinion am i better off taking the Samsung back as it started playing so early on, and getting another Western Digital? If YES what would the jumper postion be? as then i would have two Western Digital's fitted.
