SD Card Corrupted After adding video preview

grant2258

ok a few things here

your memory car reader isin working right or the lock mechanism is constantly on
the card your plugging it into isint working right or the lock is stuck on
The reader your using cant handle a memory card this size.

you can rule first the two above out by trying another sd.

number 3 would mean you would need to use a memory care the same size .

your memory car indeed is broke

On a personal note i dont use the reader in my laptop its unreliable at the best of times. I would try a usb memory card reader before throwing the card out they are only £10-15 if your in the uk you can grab one from currys/pc world.

I second that. A usb card reader also has the advantage that it can be used at multiple computers.

@grant2258 I ended up buying another sd card , I used the adapter of the new card with the old card and it still says it’s locked.

I decided just to use the new sd card and I added the image to it . I still want to add the game previews but now I’m afraid I will end up just ruining this new sd card

writing to sd should not ruin it might have been a faulty card

Since the sd card is write protected, you need to clear the read-only attribute first, then you can successfully format it using command prompt.

I'm curious, is this OS independant or will only Windows recognize the readonly flag? I ask because I searched the web for it and only found Windows related guides for this flag. No Linux-based guides or help threads that I found mention such a flag, but maybe I'm just bad at searching the web. :)

If it's Windows-only, then @Niko0422's attempt with the Linux-based GParted live system should've succeeded despite it.

Furthermore, is the diskpart method technically different from removing the write protection in the registry? Because @Niko0422 already tried the latter:

@Niko0422 said in SD Card Corrupted After adding video preview:

As I mentioned before , the card at first said it was write protected , I got rid of the write protection following the steps of this website link text under the “Accessing SD Card by modifying Registry” section . It removes the write protection, but as you can see I still can’t delete the partitions

Just trying to learn some Windows things and to ascertain if the diskpart method does anything that hasn't been tried already.

(If anyone knows more about the readonly flag and Linux, I'm also eager to learn about it. :) )

@Clyde I think it's just spam.

some memory card readers have a check for the write protect tab on the sd care and some dont. The usb readers usually ignore this tab all together. It depends on your model though.

If a device goes bad in linux it will remount it as read only. Im not sure what your asking about here exactly with the read/write flag

grant2258

if it is locked in linux i would suggest this

sudo dd if=/dev/zero of=/dev/<yoursdcard> bs=1000000 count=50

if that doesnt work
echo "0" > /sys/block/<yoursdcard>/ro

sudo apt-get install mmc-utils if you want to mess with it

@mitu Ah, ok. :)

@grant2258 Thanks!
