OK I did it. I purchased one of those fake 2TB USB Flash Drives on ebay. I ran the test I downloaded from PCNET and it errored out (after hours and hours) of course but I was still curious about the true size. I deleted the partition and created a new 2TB simple volume and Win10 let me do it but I was not yet convinced. So I deleted that partition and created a new 8GB partition. No problem. I created a 2nd 8GB partition. Again No Problem. I created a 3rd 8 GB partition and it errored out upon formatting. So now I believe it is 16GB for sure, since if it was only 8GB I should have errored out on the second 8GB partition. Can I assume I have created a simple quick way to test?
