Ahh, going into the disk managment thing sorted it, I didnt know you had to assign a drive letter to the drive, I thought it'd do it automatically like the other windows versions. Thanks!
I stuck a 20gb NTFS formatted hard drive in my PC (Formatted it ages ago on another PC), and it shows up in device manager, but not under my computer? So I cant really access the drive to put files on...anyone know why its doing this at all? Thanks.
