1tb SD card will not format

[Fido Artz]

So i got a micro sd card i ordered online from Walmart, sandisk 1 tb, sense my steam deck is a 64GB, i figured i needed to get a sd card to extend my storage memory, as soon as i got it i put it in try to format it, after waiting seeing testing... rescuing.... fail it didn't work. but the sd card seems to show up above the game system interface and it also shows up in the desktop mode explorer. So, its not exactly bricked. i tried most the methods to change the partition format of the sd card so that the steam deck game system would possibly mount it and format with no problem. All times regardless, its the same results as the first. Anyone else having this issue?

1TB SD-Cards do exist but are "quite expensive".
How much did you pay for yours? If it was below 100$ then it's most likely a fake.
I myself attempted to run a "known fake" 256GB SD-Card (is 12gb real) on the SteamDeck and surprisingly enough it realized it's a fake and wouldn't format it, only gives out an error, so +1 for the SteamDeck on that.
To confirm that your SD-Card is legit, simply google for some SD-Card Fake Testers and let that run on your card.
I personally recommend FakeFlashTest, it's very easy and userfriendly to use and you can find it here: https://www.majorgeeks.com/files/details/fakeflashtest.html

Stay safe and please report fake cards to the seller!

hold the power button down and select shut down, when you boot it back up try to format it. some people have had success doing it that way.

From what I've been reading lately keep trying to format some people said they got theirs to work after they kept trying

I would do a return and buy this. As its off SanDisks official amazon amazon storepange. Personally I always try to buy something online I try to buy directly from the company's official web sight. As there are far too many scammers on the out there. if you go to some commpanys official website they may give you a link to there official store on a third party service such as Steam or amazon. Hopefully your next perchice wont be a scam.

That's a lot of jumping to conclusions... just go to desktop mode, use it's partition tool. I'll go find a really good explanation for you. Gimme a few minutes.

This pertains to your situation but was not the instructions I found the first time. Let me read the thread to it's end.

This should be read as well... I gleaned most of the information I needed in post #63.

case solved he bought a fake SD card

also walmart allows anyone to sell on their website

I don't believe Wally World would do that either and formatting on the SD is a known issue. Sure, it could be the case but I'd rather be certain.

Please read my edit above.

Walmart recently let a vendor list a 30TB external drive for a mere $39. It was completely bogus, of course. Walmart will let anyone sell anything as long as it doesn't obviously violate any state or federal laws on the matter. And even then, they might let you list it for a while.

Go ahead, just search Google for walmart 30tb drive and read it yourself. And that's just the obvious fake. Fake flash cards are everywhere.

If it was fake, then how is the steamdeck able to detect it as 1,000.0 gib removable media on the desktop mode? that another thing that does not make sense for a "fake" micro sd card. if it was a fake it would not get picked up by the game interface, let alone the steam desktop mode at all. it would have been bricked on the spot and not be readable at all.

and if you do the math or conversion of tb to gb via google: 1 tb is 1000 in gigabytes.

A 1TB microSD card is going to be more than $150 up to $350 depending on specification. If you bought one that was $30 it is definitely without a doubt a fake card. Walmart, like Amazon, Best Buy, Newegg, etc., have a 3rd party marketplace where they allow 3rd parties to sell products through their site. You can try to return it to Walmart but it will usually show that its a 3rd party seller and will note that returns will need to be arranged with them, however, its still worth a shot to show them the scam seller.

If you're getting a microSD card, USB flash drive, or other type of external storage definitely but known name brand, from a first party seller directly from them and if possible locally in a retail store where you can physically inspect the packaging to make sure its legitimate.

fraudulent sellers will often try to make them look like a known brand. They will paint them with the same coloring and design, call them things like ScanDisk, rather the legitimate SanDisk, etc.

For example:
SanDisk 1TB which costs $225, which again in this case is being sold by a 3rd party "NGP STORE USA" rather than Amazon themselves, so I still wouldn't recommend getting this.
https://www.amazon.com/SanDisk-256GB-Extreme-microSD-Adapter/dp/B07P9W5HJV/

An Obviously Fake 1TB "Smart Card" for $23 that tries to look similar to a SanDisk, which should be reported to Amazon to ban the 3rd party seller.

Use common sense, "if it sounds too good to be true, it probably is"

Fake cards work by actually having some amount of storage available. Often 2-8 gig. Just enough that they appear to work initially. But their trick is that the controller inside the drive or card has been programmed to report a much larger capacity. So when you put it in, your computer says that it's the advertised size because that's what the device is reporting. It's not until you actually try to use that space (or in the case of testing) that the trickery is revealed. If you're just using it, it'll start overwriting files, or even the filesystem structure itself.

That is an obvious fake

They are programed to misreport their capacity which is why it isn't working in Steam Deck. Steam Deck checks the capacity using a program that tests each block of the device rather than "trusting" it has the capacity that the device is reporting.

[PopinFRESH]

Also, call Walmart and try to return the product and report the seller. On the product listing you linked there is a "Report incorrect product information" link under the specifications. Use that to report that the card is fake and doesn't contain the advertised 1TB of storage space.

[Fido Artz]

so the third party seller could also fake their return address and claim its coming from ‎Western Digital Technologies, Inc and some how the tracking address says it comes from LA or Fortuna, California and not china or some other place? If this is the case, this would make anyone leery of buying sdcards at all. even if its from the offical sandisk store. I would personally prefer a microsdcard over a ssd drives, i am not a "take it apart and mount the drive in" person.
