There is a slider tab on the side. Move it to the write position. The slider has 3 positions; up, down and middle. I found up and down would not remove the write-protection. However the middle position worked like a charm. Hope this helps someone else.
How to remove media write-protection from card reader
There are many ways to remove write protection from a micro SD card. One is to put the card in the computer and use the program that way. Another is to put the SD card into the unlocked position.
If you are plugging the micro sd card inserted through a card adapter to your PC then all you need to do is just check and unlock the lock button to remove write protection.
slide the little tab on the side.
Looking at the SD card with the label facing you, and the 'cut off corner' to the top. There is a tiny slider on the left-hand edge of the card. Move the slider down to apply write-protection - and up to remove it.
An SD card has a tiny write-protect switch on the case. If you hold the card with the cut corner to the left, the write protect switch is on the opposite side of the cut corner. Slide it towards the copper contacts to write-protect the card, and the opposite way to remove the protection.
Should be a small slider switch on the side of the card. Slide it uo.
you dont
If you are using it with the SD adaptor, the swith at the side marked lock is not to secure the micro sd card within the adaptor. This is the write protection. If you set this to the 'unlocked' position (up) then you should be able to write files onto it! very good thanks
There is a hardware protection on the card itself. It's a little slider on the side. One way is protected, the other is not. Typically, having the slider up, towards the contact side of the card, is unprotected.
slide up the thing at the right of the sd card.
Write protecting your SD card memory does not necessary guarantee a long lifespan.
