Windows 7 - Write-Protection

Hey all, how its going...
I have a "Micro SD Memory Card" and when i want to copy something at it, it gives me "The disk is write-protected.", and "Remove the write-protection or use another disk." as you see at first picture "Copy File".
And as you see at second one, I have free space more than 1 GB, so its not a memory problem.
What should i do to remove it, or to fix it, if anyone could help me, i would be thankful .
Thanks for this amazing website, helped me a lot at windows 7, and i learned a lot from it, thanks again . And keep it up.

have you tried removing the data off of it and reformatting?

I would just as a backup

be careful - most the times I see something like this it's on the verge of being corrupted - these cards are not indestructible, I've had flash drives, xd, micro sd, and CF cards crash for no apparent reason

goodluck!

yea i guess, because it wasn't working for a while, i couldn't put anything at it, and somehow after formatting it, it worked again, but I'll try to do that again, thanks .

I tried to format it, but i couldn't, as you see at the picture.
I guess i should just buy a new one.

Try the small switch on the side of the SD card.

I tried.. its not helping.. and i have a Micro SD.. but there is "Micro SD Adapter" so i can put it to laptop.. there is some solutions like:
"Start > Run "cmd"

type< diskpart

type< list volume

type< select volume #

type< attributes disk clear readonly

OR

type<attributes volume clear readonly"


but it didn't work with me, i have windows 7 Ultimate.
i don't know what is the problem :S
