Selamlar,
Flashdiski fiziksel olarak bir inceleyin isterseniz, tam emin olamasam da hafıza kartlarında olduğu gibi bir ihtimal read-only mode için bir şeyler koymuşlardır aletin üzerine.
İyi çalışmalar.

Yada kurtulabilirmi?
Merhabalar,
Bir arkadaşım 30GB kapasiteli SanDisk marka USB çubuğunu bir şekilde "Read-Only" haline getirmiş. Bunun nasıl olduğuna dair bir bilgisi yok. Benden formatlamamı istedi. Fakat ne yaptımsa diske yazamadım. Aşağıda kullandığım komutların bir özeti var.
Acaba önerisi olan varmı?
Çok teşekkürler.
Zeki

Welcome to fdisk (util-linux 2.25.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
fdisk: cannot open /dev/sdc: Read-only file system
