My micro sd is write protected, when i try to change anything on pc I get an error saying

I don't know why this is happening i have my r4 and sd card about 8months and I have never had this problem.
The card is only half full and the lock switch on the side is not turned on.

I can't even format it because of the protection

I am running Vista Ultimate if that makes a difference.

Can anybody help?

 

I just tested the adapter with a different micro sd card and it is working fine so it must be my micro sd that is write protected.
But there is no switch on that so i don't know how it would have become write protected.

 

Use the USB adapter, my SD adapters were total shit and never worked.

 

How i was connecting was with a micro to sd card adapter plugged into a sd to usb adapter. My card did not work that way but an identical card did.
I have switched since and just used the micro to sd card adapter and it works with that.

Very strange.
