I have a big issue with my external hard drive. I took 2,5" Toshiba hard drive from laptop because windows were reporting that it might stop working and all data will be lost. I bought case for external hard drive and plugged it through usb into pc. It was "write protected". Windows didn't let me to format it or do anything. I managed to format it with low level format tools but whenever I unplugged it write protection returned. My next move was to connect it through SATA cable and with GParted I formatted it, put it back to external case and plug it with usb. Now windows let me to format it and it was working until I unplugged it, "write protection" returned. I tried with diskpart, "Current read-only state: Yes" couldn't be set to "No", I forgot to mention that I took ownership when I formatted it with GParted. What shall I do now ? Please help.
