What is going on with my SD Card?

[Metalshadow626]

It keeps saying I have around 20 MB and every boot it drops down by about .7, even though I have an 8 GB card, and have always ahd 6.9 GB free until now for some reason. Don't know what it was. Could a ROM have done that somehow?

i'm not sure what's going on.. .but it might be going out... what kind of card is it? just the stock?
i'd try... first... back up the memory card on a computer... so you wont loose any files...
then format the card... and see if that helps

save data to pc, then unmount card, reformat
