Yazma korumasını nasıl kapatabilirim?
Ne denedim
- Donanım anahtarı olup olmadığı kontrol edildi - hayır
- Pencerelerde ve Linux'ta biçimlendirmeye çalışıldı (terminal üzerinden de)
- Denendi
fdisk
|chmod
- Ubuntu yazılım merkezinden birkaç araçla bunu düzeltmeye çalıştım
- Google’ı kullandı ve bu sorun hakkında yaklaşık 10.000 tartışma gördüm, ancak hiçbir zaman çözülmedi
