Testing an SD card with F3

After running f3write, it's a good idea to run f3read of course, which will you if the writing was successful, and if there are any bad sectors on the media.

What happens if the card is a fake flash? Does the write fail, or you return something other than 0 bytes free? The fake flash cards tend to overwrite the data in order to simulate the capacity. I presume that you'll get a message or when you attempt to read the data back using fwread.

Yeah when you read it back it will tell you if there is corruption.

Imagine 400gb to test. May be 12 hours or more to spend.
