Linux за българи: Форуми

Случаят е пълна илюстрация на синдрома "Ама то вчера си работеше...": след нормално отмонтиране на единия ден, на другия флашката се разпознава, но не може да се монтира. Qparted информира, че няма партиция на носителя (raw), но не може да я създаде наново. Безуспешно бе и използването на Partition Magic под Windows. Някакви идеи за спасяването на флашката или да я дам за скрап?

като я монтираш какво ди тава "dmesg" ? , ако я монтира правилно значи може лесно да се форматира по какъвто искаш начин , аз имаш проблем с една таква kingston и проблема накрая беше чисто хардуерен

Изходът от dmesg (в частта, касаеща USB) е:

С X-Edit (под Windows) опитах да записвам 0 (нули) в първите сектори, но безуспешно. Явно става дума за хардуерен дефект.

Еми, пробвай я на друг компютър щом се съмняваш за хардуерен дефект. Ако и там не работи, пробвай да и сложиш по-нов firmware. Ако няма по-нов, просто преинсталирай текущия. Ако и след това не работи нито на твоя компютър, нито на някой друг, тогава можеш да я дадеш за скрап

А с fdisk или cfdisk пробва ли да я оправиш? Никога не съм се занимавал с усб флкашки, но преди няколко дена една микросд крта ми скъса нервите по същия начин, даже в win нито една програма не можа да я разпознае. Оправи се като изтрих старите дялов и създаох нов. Всъщност само fdisk успя да ми помогне. Пробвай, може да върже...

Решен:

Направих доста проби, под Linux и Windows, но безуспешно - докато не попаднах на JetFlash Recovery Tools (Windows) - руска програмка, която успешно успя да възстанови флашката. Единственият страничен ефект е, че под Windows се разпознава като JetFlash устройство.
