I have a new HP Pavilion desktop running Windows 8. I had a second hard drive on my old computer that contains important tax documents I need to retrieve. The old computer is currently defunct. An IT person I used to work with suggested an external Hard drive enclosure would be my best bet. I bought that and installed the drive, but when I plug it into the USB, my computer does not recognize it. I'm not a tech person and I'm lost with Windows 8, as it's nothing like what I'm used to. I've tried different cables and different ports with no luck, and have invested hours trying to make this work. Can anyone help?
