Kiedyś odpaliłem Gparted na virtualboxie, zamontowałem kartę SD, sformatowałem i od tego czasu nie mogę nic zapisać ani usunąć. Na karcie są pliki z telefonu. Obojętnie co robię, na karcie nigdy nic się nie zmienia. (na adapterze jest odblokowany zapis :p)
Próbowałem zastąpić wszystko zerami poleceniem dd, całą noc to mielił i w końcu wystąpił błąd.
To zwraca program gdisk Warning: Secondary partition table overlaps the last partition by 33 blocks!
a tu szczegóły błędu formatowania z użyciem gparted (już normalnie zbootwanego przy starcie systemu):

Partition(s) 2 on /dev/mmcblk0 have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.
