Selamlar,

biraz eski ama söyle bir bilgi var:
http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/Sandisk-cruzer-16GB-became-read-only/td-p/255218/page/2

Eger ayni usb sticklerden ise fiziksel olarak read only hale gelmis
olabilir ki bu durumda yazilim tarafinda yapilabilecek bisi yok. Garanti
süresi gecmediyse ürün degisimi talep edebilir. (Not: Tabii önce bu
olasiligi kesinlestirmek ve sorunun yazilim tarafinda olmadigindan emin
olmak lazim.)

Iyi calismalar
Selim
