No Media after running

[bbislander]

I have been using the drive but wanted to wipe it and decided to check it's supposed size of 1tb was genuine and ran it through with Media Tester which checked the size with writing and reading randomly over the drive. After which I just got the No Media message from windows. Has this been noted before?

I'm not saying that the next thing I will say was what happened to you, but...

I have fake USB-pens/SD-cards (and legit ones that simply stop working) in the past that after being fully tested with "Check Flash", that quit working and some of them happens exactly that, they no longer get detected.

This normally it's not the fault of the programs, but the pens/cards that simply stop working correctly.
