    Hi. Welcome to the forums. Is this a new sd card? If so where did you buy it? What brand is it? Sometimes if we buy from sellers on Amazon the cards can be fake and will cause problems in using them.

    One other thing, try in your Mac/PC where you have more options.

    Hi, welcome to AC!

    Sounds like you have a bad sd card or counterfeit

    That is addressed specifically in this article: https://www.makeuseof.com/tag/how-to...-microsd-card/. Huawei doesn't make microSD cards.

    The other day I tested a few "32GB" microSD cards that I had gotten from Wish - and they all returned only the first block - which was unreadable. So why did I buy them? The card plus the reader were cheaper than buying the same reader just as a reader. (Go figure the psychology of that one.) The cards are either 16KB (which I can't format in Windows, and I don't want to reboot to Linux) or they're just defective. (I could report them as defective to Wish - they issue refunds with no problem - but I got what I wanted, so it wouldn't be honest. [I really didn't expect 32GB cards for the price. Maybe 64KB working cards, but they would have gone into a little plastic case as "defective but they fill the slot anyway" cards, which they still do.])

    You're welcome.

    The point was that a $2 SD card at wish isn't going to be a 32GB card (let alone a larger one) - but the readers are over $3 when purchased alone. Since I needed a few, and I could get them "picked up" (no shipping), I saved about $10 all told. (For one it probably wouldn't be worth the wait - Amazon has them for about $8. Even eBay has them from a US source for under $4.)

    The readers are ok though to purchase from them ?

    I got 10 of them. They all work fine. (I just now finished copying 5 iso files of about 3GB each to a 512GB card - and they went with no problem.)

    Same here. Wow, like you stuck at 20%, it also did the same thing in another device originally hence why I thought I'd also try to format it in my N20U. It was a transcend 64GB genuine from the manufacturer itself.
