Есть флешка transcend premium 400x microsdhc 32GB. Из коробки она даже работала, но при попытке что-то записать падала в ro. Пересоздал таблицу разделов (пробовал, как в gparted msdos, так и в fdisk o), создал раздел (mkfs.vfat с 0 завершается). Теперь не могу даже примонтировать:
$ s mount -t vfat /dev/mmcblk0p1 /mnt/mmc
mount: /dev/mmcblk0p1: can't read superblock
