I bought a 1G SD card a while back (3-4 weeks ago) and when I got it home I formatted it to FAT file system. I checked the properties and there was 998 MB left on the card. Over time from adding and subtracting files a whopping 32 MB of space has disappeared and I can't get it back even if I reformat it again. Does anyone know why this space has disappeared and is there anyway I can get it back? Is it just bad sectors or something similar? Should I take it back to the store I got it from or is losing space just one of the quirks of this kind of media?
