i've got a 6630 and it says that my mmc is corrupt. i tried formatting it in the phone but no results, so i bought a card reader. i tried formatting it with the reared but it says "windows unable to complete frmat", any idea on what is wrong??
Sounds like a card gone bad (=broken). Don't know why or how, though. If reformatting it doesn't help, you'll need a new card (or at least I don't know of any way to fix it).
