I got scammed by a couple of fake cards. Here's how to protect yourself.

To put it bluntly, it would be foolish to buy media or a drive and NOT test it with this free tool. It's fast, simple, and does not even need to be installed.

A problem ordering things like this from Amazon is their commingled inventory system, especially with third party sellers. Even if you choose a specific trusted seller, Amazon often commingles SKUs from different sellers, as they are supposed to be identical. They may also commingle their own inventory, which is why ordering 'Sold by Amazon/Shipped by Amazon' STILL isn't a guarantee of getting genuine product. Thanks for sharing this tool.

I was scammed here in SA a few years ago with a local small pc shop selling San Disk flashdrives and they all were fake not just corrupt data but it said 32gb on the stick but real size 1gb. Good video also a proof to rather try and get stuff from a reputable seller.

I have a stack of 2.5" spinning drives as backup, i use a SATA to USB cable, works fine
It's only the 3.5" drives you can't use with that cable, you need 12V as well, you can get 5v/12v bricks with sata and molex power, just need sata data cable

My question is what software exists for Mac OS?

These drive can still be used. Most of the time you can create a partition with the working size using computer management in window. After that the computer will only see the working part of the SD card and work as normal.

I just got 4 sd cards from temu. Guess I better find a windows machine and test them.
