Remove the write protection on a Micro SD.

When I got my phone I got it for the mp3 player. What I didn't know is that they expected me to buy a $30 connector cable. I tried to be the smart consumer and just bought a Micro SD card with an adapter. I plugged that bad boy into my computer only to find out that it was write protected. I figured out the painfully obvious way to unlock it.

grab some tape and put it on the lock so that it won't be able to slide. It worked for me and it will work for you. put the tape tight so that it won't be able to slide.

Actually, what happens is that when you insert the card it is not locked but the moment you put it in, slide automatically locks it and when you take the card out the slide return to unlocked position. DONT BE FOOLED BY THAT, CUZ I WAS>
Sometimes, when i didn't knew the tape method, i used to spend hours reinserting and luckily it worked sometimes but putting tape is the best method.

Must return to state that after many failed attempts with one OHM SD adapter to remove write protection by formatting the disk, I tried another adapter and the disk reformatted the first time. Old adapter is in trash.

Folks: If you tried some proposed fix and it worked, hooray. Tell us what you did that worked. If you tried some fix and it didn't work, tell us what you did and what didn't work.
I've tried every proposed fix on this list and none have worked on my San Disk microSC card. I'm trying to download Go Pro software and disk stays write protected; so far.
I had a PNY adapter that simply refused to respect the position of the write-protection switch. However, my Transcend adapter worked fine! So if you're in this situation, try a different adapter!

hey there im having so much trouble with my sd card , its an 8 gig and it has alot of stuff on it i want to get rid of it all and replace it with new stuff but wen i plug my mini sd into the adapter , i can open and look at what is on the card fine but its not letting me delete anything becoz it says write protected .... SOME1111 PLEASEE HELP ME !! LOL
There should be a switch on the side of your adapter (normal sized SD card) just switch it to the other side and it should work.
Ok all you have to do is get clear tape and put it over the switch be sure the switch is up instead of down see basically what happens is when you insert the sd card in there it locks itself so to prevent that you have to unlock it and make it stay unlocked even when you put it in your computer. Be sure not to cover the gold contacts as you may result in damaging the SD Adapter.

All You gotta do is take out the adapter look at the side. It should say lock on it. If the little switch is on the arrow then move it up and u should be able to put files onto it now.

Good grief. Was getting that blasted write protected message, but couldn't find a switch on the micro SD looked for it on the adapter and still could see it. Then I used a finger nail to see if it would snag anything, sure enough there it is. On this sandisk breed both the adapter body and the switch are both black. Good thing I did a web search before I tossed it in frustration. Now I don't know what to think, Windows said formatting complete, file manger shows no files, but my phone tells me the card is full. Next to read the phone manual. Until no I thought the protection in the full sized card was an actual electrical switch, but evidently it's optical like floppy disks

i have a adapter but it does not have a switch (must of been broken off) and the write protection is on it. Is there any other way i can get it off?

I'm having a problem with my Micro SD 8gb.. cant reformat it, cant delete files. So I guess it is write protected.

all you really have to do is slide the switch into the 'unlock' position, put a piece of tape over it (making sure not to cover the copper connectors on the adapter that slide into the computer) and the lock button doesn't get activated when you push the card into the computer. this will allow you to keep the lock button so if you use the card to store tools for repairing computers the card is still protected from having a virus or malware written to it by the infected computer.

The lock switch doesn't lock the microSD into the adapter;
the lock switch doesn't lock the data on the microSD;
the lock switch by its position (or more exactly its presence at a place) tells the *reader* not to write.
It just says "please don't write me."
I'm sure a reader could (whether broken or intentionally) bypass this.
Now if it could be done in software, thus (farfetched or not) permitting malware/viruses to get onto the chip .... <shrug>
Have fun! (I'd forgotten all this from my punching-out-tabs days with tape cassettes.)
=e
in the "reader" is a push-button, which is pressed by the "lock" (the plastic thing) if its writable. if the button isnt pushed, the reader doesnt want to write it. (and tells your OS not to write)
you are right, the function of the lock does actually seem to do something outside the card rather than inside it. as you said, it must be pushing an button unlock button in the card reader. if the slider is broken or pushed down to the "lock" position, then when you slide the card into the card reader, that "button" inside the card reader does not get pushed.
I wonder if People remember 3 1/2 ' Floppys Ive got loads of old data on those things and haven't had a 3 1/2" reader in years lol
I opened up one of those adaptors today and discovered like you say that the lock switch just bridges two contacts...
LOLX

Back to the original post, I don't know why I didn't point this out up front: I've bought micro-USB to USB cables for like $2 or $3 apiece online. A price like that definitely changes one's attitude.
