SOLVED!!!!

I solved the problem .
I think the problem was with the little peace of plastic,the lock-unlock peace of SD card.
I used a peace of toothpick to replace the lock part on sd card & duck tape to keep it in place

.

The card is now readable , not write protected.Already formated to 1.88Gb.

TY guys

Gparted can only change unmounted partitions,
you see the set of keys, this says that the partitian is mounted and therfore locked to changes,

right click on the keys then select unmount,
when they dissapear you should be good to go

The question wasn't about mounted or not device when I tried to format ( both mounted & unmounted),but about write protection

accused by faulty locking device on SD card.

But Thank You.

Just a couple of thoughts. On the side of your SD card is a slider switch.Pushed towards the contacts end it is read/write, pust away from the contacts it is read-only protected.

Secondly
open a terminal
su [enter] to root
cd the_SD_card_name[enter]
ls -l[enter]
look for rwxrwxrwx against each entry

issue command
chmod 777 * [enter]

you should now have read+write for any user ID.

Test by typing
echo My new file > temp.txt [enter]
ls [enter]
cat temp.txt [enter]
