AFAIR fdisk can show this info. Had the same problem with SE 64Mb card in K750i. It turned out that SE creates FAT12 on a 32+Mb disk, which is not supposed to be an option. Some time ago this was discussed, but I was unable to provide a dump from such card (have no such card anymore). PS. To just make it work - just re-format it and restore folders structure. But please, create a filesystem dump first, to let developers decide is it a fault of SE phone or MSDOSFS code.
