Can't see MPC partions on PC

Yes, here's another compact flash problem.

My dear MPC2000XL can see the card, its says Atapi HD.
I CAN format it on the mpc.
I CAN only format in an A+B partition.
I CAN make new folders.

BUT i CANT open the CF-card on the pc. I cant reconize it.

When i format it on the pc, and put something on it (wav file). Then the mpc does not see the file.

Why is there a A+B partition? Why cant i read MPC formatted cf on the pc?

I have a PhotoSteno Pro II card (1gig) and using OS: 1.14

Please help, i need my baby to work.

PS: Yes, I have the right jumpersetting, and yes the right cardreader.

I allready fixed it myself.

For the people who have the same problem:

I updated the OS from 1.14 to 1.20, and i replaced my IDE flatcable for a new one. That made it work.

I'm going back to work now
