Weird problem with my MPC...

Having a problem with my MPC:

When I connect my mpc to my mac or PC to drag drums/samples to the flash card, I get "cannot copy because there is not enough space" but theres 70 MB left on the damn flash card and the total size on the drums I'm tryna add are less than 5 MB. What da hell is wrong with my flash card???

Did you actually select the memory card to access in the USB tab in Load/Save Mode?

He must have otherwise the memory card wouldn't show up.
You need to hit usb to access it on your desktop.

I think the problem is a corrupt sector on the memory card.
Could have happened during format.

Move all your data across to your pc, reformat the memory card and try again.
If the problem persists then it could be a hard corrupt sector.

format ur card again then turn off ur mpc and the reboot then should work
