Merhaba millet, elimde bir usb bellek var ve nedense içerisini sıfırlayamıyorum. Gparted'ta ve terminalde fdisk ile denedim ancak sonuç alamadım. Sanırım partition kısmındaki anahtar işaretinden ötürü oluyor. Bu konuda bilgisi olan var mı?

The kernel still uses the old partitions. The new table will be used at the next reboot.
Bilgisayarı, silmeye çalıştığınız bölümünün bulunduğu USB yani sdb ile mi başlatmıştınız?
Anahtar ikonu, o bölümünün kullanımda (mounted) olduğunu ve üzerinde bölümleme işlemi yapılamayacağını gösterir.

Siz diyince farkına vardım. Doğru bilgisayarda üç adet depolama cihazı bağlı halde bulunuyor. Biri bilgisayarın hard disk'i, biri linux mint'i live disk olarak başlatmak için kullandığım diğeri de içerisindeki verileri sıfırlamak istediğim.

Live disk olarak başlattığımı unutmuşum, o iş için kullandığım usb tırnak kadar.. Peki diğer usb neden görünmüyor olabilir? Windows'da taktığımda "Giriş/Çıkış hatası" diyor ve usb'yi açmıyor. Daha önce böyle bir durumla karşılaşmış ve linux üzerinden gparted ile halletmiştim. Geçen gün gömülü sistemlerde linux yönetimi ile ilgili bir kitapta da fdisk'in anlatıldığı kısımdaki komutlara uyarak diskin içerisini sıfırlamaya çalıştım ancak sonuç alamadım.

Terminal üzerinde yaptığım işlemlerle hangi usb'ye dokundum acaba :D Zira linux live disk için kullandığım usb içerisindeki ne partition ne de verilere bir şey olmamış. Ancak terminal üzerinde sildim diye biliyorum.

Benimde başıma defalarca gelmişti. Aslında bir kaç komutla çözülüyor.
