In July my old HP Pavillion power supply unit died, so I purchased a new Compaq presario desktop. I just had the power supply unit replaced in my old system so I could get to my old files. I had purchased a Seagate Freeagent 500GB external hard drive to put the old files on, which was done successfully. I now have the external hooked up to my new system but I can't get it to install and then run to be a back up for my new system? Will it now allow me install and run on the 2nd system?


If this is a usb external drive then it will be shown as a removable drive in My Computer. Just right click on the icon>Explore and you should be able to view the files on that drive. If you do not see a removable drive then please post back and I wi ... PC Desktops
