Which card? Does it read on PC?
Try formatting it on the PC (as FAT16 if it's <=2GB card, as FAT32 if
it's 2GB+ card! Not NTFS or Mac or whatever).
If it works:
Then, use some software that scans the "surface" for read/write
errors.
Then, format it in the camera again.
Hope this helps...
Good light!
