i've tried CS, SLAVE and MASTER settings. doesnt like any of them at all Is there a jumper to limit the HDD capacity? Try that incase your bios is having problems with the large drive. Still seems like it would atleast recognize it though... yea there is, and i just tried that and it's had the same problem. its just ticking over like it's trying to read the drive but something isnt letting it inside. i'm proberly going to ring up the company i purchased it from first thing in the morning and send send it back. i'm 99% sure its a faulty HDD and not a failure on the human side of things. jus
