So for no good reason I tried enabling BitLocker on my 4GB mSD card. It ran for a min or so then suddenly showed something like "The data on the drive was changed". I clicked Cancel. After that, the drive seems to be unformatted. But when I tried to format it, Windows told me that the SD's size is 13MB. And it couldn't format the SD anyway. So far I've tried the default formatter, SD Formatter, a partioning tool and win32disk imager (shows a bunch of data in HexEdit). But I still couldn't bring back the full 4GB capacity. Are there anyway to properly format this drive? The data isn't important, I just want the full capacity back.
