Você tem alguma sugestão para entender qual é a razão disso?
Eu tenho um cartão SD SanDisk que exibe um comportamento estranho:
adb pull
data, recebo os mesmos erros depois de um tempo. Depois de tentar formatá-lo no HTC, recebi uma mensagem:
Unsupported SanDisk SD card This device doesn't support this SanDisk SD card. Tap to set up in a supported format.'
Depois de continuar, configure o cartão SD SanDisk - Use como armazenamento removível. Formatar como armazenamento portátil.
Então eu recebo a mensagem command '196 volume partition disk:179,32 public' failed with null
