I bought an USB thumb drive of 64 GB, to check its size I did as the answer in the link bellow instructs:
Check real size of USB thumb drive
Here's an image from my terminal executing the commands:
My terminal output (red rectangle)
The f3probe
indicates an actual size of 32 GB.
The seller said that this is incorrect and uploaded an image doing a counter proof:
Showing the size of 61 GB.
Are any of those tests reliable?
If yes, which is right?
If my test is the right one, it is enough evidence to win a dispute in Aliexpress? Case it's not, which evidence should I add?
