PSA verify all sd cards you buy.

I bought a 512gb micro sd card from Amazon got it a few days ago and had trouble formatting it on my android phone. The phone is compatible so I spent more money on a micro and sd card reader. Turns out it failed because the card is a fraud and actually only 8gb. I know we all hear about fraud cards but I bought this from Amazon LLC as the seller aka Amazon the company is also selling fraud cards. Just note this because most people learn there fraudulent when it looses important data (fake cards normally are only 8gb when you put more than 8gb on it well that data is lost). Pictures included

What's interesting is that the EVO Select brand is an Amazon exclusive, IIRC, so somewhere in the supply chain would have to been compromised.

Thanks for mentioning that as it seems important to be noted.

That picture of the capacity isn't a valid way to check the capacity... Clean the card with diskpart , make a new partition and then take a look. Partition table could be corrupt or good old Windows not wanting to deal File Systems it sees as unworthy...

If the capacity increases after that and you still suspect if the capacity shown is true, try to fill it up and see if fails to do so or not.

I already did that. I've dealt with messed up sd cards and usb flash drives after messing around with Linux installs. I've tried everything I can. I cleaned it and it still won't format. It just fails regardless.

EDIT: To clarify when I clean the partition and go into disk partition there's still a partition on the sd card. If I try and delete the partition I get "The request is not supported" and if I format it I get "The format did not complete successfully". So not quite sure what's going on but regardless it appears to not be just broken but rather fraudulent since its not the correct size. Possibly its messed up in a way that I just don't understand but with how common fraudulent sd cards are I'd assume its that rather than something complex. ALL I know is I hope my replacement isn't messed up so I can FINALLY move over my music library to my phone. If anyone has any idea on what else to try lmk as its already broken can't really mess it up more than that.

I can't help but wonder, could it be a premature failure? I remember I once bought a 16 gig USB 3 Kingston flash drive at a Bartell Drugs (another place where it's very unlikely that it was fake) and after about 300 megabytes of data being written it simply wouldn't take any more writes. I could reformat it but it could never write more than a few kilobytes after that, even 8KB documents would fail at around 2KB so it was a very strange failure that wasn't 100 percent failed. Considering how that makes no sense even for a fake drive, I can't rule out the possibility that your experience could be that of a rare dud. Can you?

There's tools that'll test flash drives/memory for fakes, check some of those out and get to the bottom of it.
