    Have a ~1.5 year old 128GB class 10 card that can't be overwritten or formatted even with cmd and fancy software. Worst case is I buy a new one, but agh they're pricey.

    No read limits. Don't worry about write cycles. There is actually more memory on it than you think. The spare memory is reserved for wear-leveling to ensure your SD card lasts a long time. Most likely your old card is just broken. Do not do NSA / NIST secure deletes with x30 overwrites. That will kill the card faster.

    Have a second copy, don't worry about it, let it wear out (in 1day to 10 years, hard to say ;D)

    Like Marv said, reading flash doesn’t hurt it, only writing does, and it takes lots of writes to do so

    Did you try formatting with gparted? On Linux as a program or on Windows using a Live CD/DVD.

    Thanks guys! Yeah, that's what I thought too, which is why I think it odd that my card crapped out after only 1.5 years. I basically dumped my fave albums into it so I wouldn't have to keep cycling, haha.

    Just sucks that I have to wait until I can afford/get another SD before I can have non-Spotify music on the go again, agh. (phone internal full of VR games atm, lol, and I got the lowest storage option)

    Also, might just write it off (hah) as a loss, no success formatting despite the combined powers of Google search and all available freeware on the net. Ah well, this sucks feces.

    EDIT @mitochondrium Yup, I tried that too. This card is just bollixed beyond redemption I think. EDIT 2: nope, I'm dumb, it was a different partition thing. I'll give this a shot, thanks!

    I've seen USB sticks go into a read only mode, maybe triggered once there are no more good sectors left. Buy branded is a good idea: Samsung, Sandisk, etc.

    Yup, buy good brands and use Linux tools.

    Lots of good advice, I’d have said the same. Only addition would be to be cautious of fakes and buy from somewhere reputable.

    It’s been awhile but systemrescuecd used to be my goto for this stuff, and it includes a lot of other tools besides a partitioner.

    It was a SanDisk card, but for whatever it's worth I seem to have had better luck with a Samsung. Maybe my luck will take a turn since it's a Samsung phone too, haha.

    As for Linux tools, been a while since I used those so have to take a refresher. It'll give me something to do I guess :P

    @BenjaminBore Welp, only thing I can keep doing before buying a new one is trying as much as I can to sort this out, haha. The advice has been excellent (thanks all!), though I hope this isn't the sort of thing that happens often enough to warrant going back to this so often :P

    If you're on windows, then diskpart for parition management. But you have to be careful as it's command line only and you can wipe your OS if you're on the wrong device :)

    I am very careful of where I buy SanDisk branded cards, it's the most commonly faked brand out there.

    Diskpart off memory:
    Diskpart (run from a command window with admin rights)
    > List disk (figure out which # is the SD card X)
    > Select disk X
    > List disk (to confirm you're now on the right device, look for the *)
    > List part
    > Select part 1
    > Delete part
    Do the last two steps for all partitions on the SD card.

    If you forget to select disk as the SD card, you'll end up wiping your OS partition.

    Thanks! Diskpart was the very first thing I tried, didn't help, so I'm guessing this really is beyond salvation.

    And don't worry, my computer survived:))

    quick update: Okay, so any attempts to format, write to, or delete data off the disk has failed, but I can still read off it so I guess I can just plug this into my PC and save my HDD the wear? Hah.
