The question is why has Uniden scanners, Yaesu radios, dashcams, and many things I own need only 32 GB cards? Other than my Nikon D3x camera, everything else only accepts 32 GB cards and no one at OfficeMax carries them. They have a plethora of 256 or 512 cards, but not anything sub-64.

Any educated guesses?

Some devices will still use a larger card just will not read past 32 GB. I would try a 256 or 512 with the scanner. All my Raspberry Pi's have 256 or larger cards for the OS because they readily on the shelf.

SD cards max size are 32GB in native mode but it can use a non defined page flip mode to switch to another 32GB bank but that flip haven't been set as a standard and might be uncompatible with some devices and are the reason to that only up to 32GB are guaranteed to work.

You can get 32 GB cards from Amazon or eBay. Some of my radio equipment will only take 4 GB cards. Be sure the card is formated with the right format.

Always be cautious of cheap storage, especially SD cards. The larger the capacity, the more likely you can find counterfeit cards that spoof their capacity in a partition table or by other means. If the capacity per dollar sounds too good to be true, it is.

Oh. What the heck. Bottom line. Order and wait for a known genuine data card if you need one that isn't readily available.
I do repairs here. SMD. You name it. Data recovery. Have jigs, software.
Most all programs for factory USB, etc. factory firmware flashing is 32 bit. And Windows XP compatible. So yeah, XP is still a usable platform.

Had a fellow show up in a panic. And it's always a panic. A storage card that had been through 2 iPhones and an Android.
About a billion pictures and stuff on it. Description was that the Android phone's battery ran down. After that, the card was corrupted and unreadable. And typical, it was never backed-up to a pc.
Fake cards are very difficult to do even a bit copy. I was able to get somewhere like 90% of the stuff on his card put back together.
With a lot of .jpg's showing partial images and the rest just a black void. The card was a real Sandisk.

Dollar Store you say? I got my "need it fast" card from the specials table for a steal. They said if it don't work that I could return it.
It's been in my IC-R8600 for a long time. But don't think for two seconds it's not backed up on my pc.

Other's. The software shows the chipsets. USB drives are notorious for borking. How many do you have that you can't even format?
So. Don't trust data cards. If you have an option to unmount or safely remove device before pulling it. Or just power down the device 100%.
Do it. Each and every single time.
There were a batch of Sandisk 64 gigabyte USB flash drives that they replaced. Even if you babied them by doing all of the right things.
They died, corrupted, refused even a format.
Backup, backup, backup. Haha. There's a palm for your chin to rest on.
