Notebook's card reader can't read memory stick pro duo 4GB

[rdmpe]

I have a Fujitsu N6010 notebook (approx 4 yrs old) with a built in card reader. The reader will accept a memory stick duo.

I put my pro duo memory stick into a "standard" duo adaptor and put it into the card reader. The computer seems to see it and I get drive E: to show up in Windows, BUT if I try to browse drive E:, I get a message "Please insert a disk into drive E:"

The card works fine in my camera and I can browse the card using the camera attached to the notebook via usb. I guess I could have a faulty adaptor as well but it seems like a very simple device and the computer does sense the card there, just seems unable to read the card formatting or something. I have also used the camera to format the card, but that didn't help.

Fujitsu has not issued any updated drivers for the card reader. Any ideas??
