Cannot Mount, Read, Write, Format Minisd

Hi guys,
I can't do none of these things on 2 64mb minisd: following some info...

ERROR:

TRY TO MOUNT:
[hysoka@myhost mnt]$ sudo mount -t vfat /dev/mmcblk0 /mnt/sdcard/
mount: /dev/mmcblk0: impossibile leggere il superblocco (unable to read superblock)

TRY TO FORMAT:
[hysoka@myhost dev]$ sudo mkfs.vfat /dev/mmcblk0
Password:

mkfs.vfat: failed whilst writing reserved sector

Help guys, how can I format these damn minisds in order to use 'em?
Since both of them give me the same problems, I guess it's probably a hardware support issue... but you tell me!
