I purchased a Samsung EVO Plus 1TB Micro SD card new from a seller on Mercari on 8/19/24. I got the new, sealed package, which looked legit, and okayed the item with Mercari. Then when I tried to copy 377GB of video files to it, it stopped with errors are copying only 64GB of files to the card. No device (my Samsung tablet now my Windows 11 PC) could copy anything else to it, though it showed 8974GB of free space. Testing with H2testw verified that the device was defective and too small.
