External Hard Drive Visible but not accessible

I had a Seagate External HD connected to an old Gateway Desktop via USB running Windows XP. The drive has never made any noises & the lights work like they always have. It disappeared from Windows Explorer. When I uninstalled & attempted to reinstall, it never made it through the add new hardware wizard. Wizard just froze. I took it to another Desktop, a Dell running XP. It made it through the Add Hardware wizard but was not visible in Windows Explorer again. In Device Manager it had a bunch of symbols & some foreign language as it's Device Name the first time. I uninstalled & reinstalled again. This time it showed as storage device in device manager but was still not showing up in windows explorer. If I can get it to install on the Dell again & show up again in device manager, how can I get my files off it without being able to access it through Explorer?


edit: I should also mention that shortly after this my gateway gave up the orange light & would not boot. I am assuming the PS is dead as the test button kicks the fan on for a split second & then dies while the MB green light is still on.

Thank you in advance!
