Ok Nev will try it tomorrow although working until 6pm so will be much later, had a couple of glasses of wine so prob best not to try anything tonight :)
What does it mean unless the drive is Sata what does that refer to? how do i find that out?
The other hard drive i was talking about came from another laptop on which, apparently the motherboard has gone (might open another thread about that one!) which i tried to connect to both another laptop and also a desktop, on the laptop which runs windows 7, the laptop was vista, it registered the connection but wouldn't open and on the desk top which is windows xp it didn't even show it was connected.
thanks again for all the help so far
