I have an HP Pro Book with an internal drive partitioned into three volumes (C:, D: and E:). I also have an external USB hard drive (G:) attached which I use for backups. Before this I had a Dell laptop from which I rescued the two internal disks before the computer died and put them into their own case/caddy. These disks work.
My problem is that when I try to connect them via a USB cable to my HP, the HP doesn't recognise them or pick them up. I have a feeling that the problem is related to drive letter allocation but I'm not sure. I've already tried changing drive letters through Computer Management and that didn't work but I also think here that I may not have done it correctly.
Advice here would be really appreciated. I need to get access to the info on those drives.
