Force eject

I have a MPC 1000 with jjos2xl and everytime I hook up the usb I can't eject and have to force eject.
All my files are fine so far but I don't think it's how it should be. If anyone knows the problem I'd appreciate some help.

well the good news is... by that point it's already connected to the computer so you can back up the data on the card in case it does get ****.

Haha true maybe I should start backing up on my computer now :p
