I was trying to save a song on the hard drive and hit a wrong button.
Now when i turn my mpc 2500 on it says

on the card. Then i put it into the mpc it might read it it if anyone knows what i can do i apperciate
your thank you

Sounds like your [WINDOW] button might be stuck.

Try reinstalling the OS.
