I had the same problem but it wasn't my phone that was the issue. It's with the card itself. If your using an SDHC card, they can sometimes have ECC(error correction checking) and since the 6700 doesn't support that it may cause issues. I have a class 6 card but class 2 and 4 also have ecc. What you can do is reset your phone, put your memory card into your computer, use chkdsk to check and repair errors, backup your sd card data to your hard disk; and format the card. Then once its formatted put it back into your phone and it should work flawlessly.
