Hi
My pc recently died so i aquired another one, i had lots of important files on my old pc's hard drive so i've removed it and tried to add it to my new pc. I have connected it as 'primary slave device', set the jumper correctly and powered up. A message in the bottom info bar read 'found new hardware' and then 'disk drive' however, when i checked my computer the drive was'nt there, only the main hd (C:) and cd/dvd (D:). Both the installed primary drive (C:) and my other 'slaved drive' are ide devices. The drive is visable in device manager but i'm unable to locate or access it. Any advice here would be much appreciated..

Thanks
