Eu tentei usar adaptadores físicos para desativar o bloqueio de gravação, desabilitando os registros de política de proteção contra gravação no Windows, usando diskpart para limpar o atributo de proteção contra gravação e usando gparted para formatar, reparticionar, limpar, substituir e até mesmo alterar a arquitetura do MBR para o GPT.
Referenciando o sdtool de bertold:
Most SD cards have a physical write protection switch. This switch is read by the reader instead of being enforced by the card. Of course, many readers ignore this signal and will happily write to a write protected card. Furthermore, Micro SD cards do not have a mechanical switch.
It is relatively unknown that SD/MMC cards also have an electronic write protection system. Every card has two programmable flags, one for temporary write protection and one to lock the card forever. Writing these flags is not supported by most SD host devices. To remedy this, this page presents a program that allows a Linux host to configure the protection register.
Eu tentei compilá-lo, mas parece que faltam recursos em "obj".
