Passport Portable 250 NOT recognized by XP

My Passport contains files from an Windows XP PC. It is not compatible with my new Windows 7. I want to download and transfer my old files, but the Passport is no longer even recognized by XP on other computers. LED is ON. Is anyone familiar with my problem?     

If it’s not compatible with Windows 7 there isn’t much you can do about old hardware. There are a couple things to try but aren’t simple. You might make a virtual PC running XP on VMware Player and see if it will access the data that way. If you still have the XP PC transfer the data back and network it to Windows and transfer that way.
