Have you actually tested this before posting? I have, and it does not work. It seems that these cards are crap, and it's beyond repair.

The problem may be that the electronic device you're using, it may not support the capacity of the card. For example, I have a digital camcorder that's from 2001 and a camera from 2008. Here is the information displayed using fdisk under Linux for a 2GB SD card:
When the card is in the camera:
Disk /dev/sdd: 2021 MB, 2021654528 bytes
When the card is in the camcorder:
Disk /dev/sdd: 1010 MB, 1010827264 bytes
As you can see here the camera reports the correct capacity, 2021MB, the camcorder on the other hand reports only 1010MB. In the user manual for the camcorder is says it supports 8,16,32,64MB SD cards so it appears that the camcorder firmware only supports SD cards up to 1GB. The problem might actually be in the firmware of the electronic device being used and might be fixed with a firmware update from the manufacturer if one exists.

This problem can occur if there is a Linux image on the drive. In that scenario Windows does no see the drive as a whole, but as two separate devices, one of which Windows can not see at all. That is why SD formatter cant change the size of it, its not showing as a partition, but as a device. If you have a machine running Linux, pop the card in there and use a disk utility to fix it. If you dont, download the gparted-live iso, burn it to a cd and boot from it.

Same problem here, but for a 64 gb model. Quite bad.......
What caused the problem:
Trying to create an encrypted osx file system on the SD card.
(plz don't discuss the WHY now)
What i did so far:
Testing in Win/Lin/OSX. None of the tools works. dd can just copy 32 mb, fdisk won't write any new values.
Also testet different adapters.
Also tried in n900. Does not boot with the card.
Formatting in an Android tablet does also not help.
Last hope would be the GoPro camera?
But i guess i burned the card......

I know this an older thread but I solved this problem using the following: https://www.sdcard.org/downloads/formatter_4/eula_windows/
Hope this helps somebody out

this worked for me. I selected the Format Size Adjustment to "on" under the Options button. the 297mb card magically had 29.7gb after formatting. pretty sure the card was linux formatted for a cyanogenmod boot drive which is why it did not show full capacity. thanks a bunch unklefunky

I have a 16 gb micro sd card that i have for my galaxy s3 but it wont format. I even tried to format in on my computer but the computer states it cant compleet the format. I have only had the SD card maybe a week.
