Windows Administrative Tools -> Computer Management -> Disk Management
Find the SD card, right click and delete all the partitions on the card (it might show several) remove them all until it's got none, then add a new Simple Partition taking the full size of the card.
Some tools like Win32 Disk Imagers change the disk layout so you need to manually restore it.

I tried to read it using car reader on my pc. Some readers cannot see this card, but some can see and ask format it, when the format dialog is appeared is shows that card has only 31mb of storage and I can format it in fat or ntfs. But if I click format I'll see the error message. Also I try to insert card into Nokia N96. It also can see only 31bm can format it and I can write something but cannot read. If I turn off the phone and turn on it again, or release insert the card the phone asks me format it again.
