other than losing the drone - worst nightmare this morning

Counterfeit cards will do the same thing, I learned the hard way. I had a 64GB SanDisk from Amazon, that was in fact only 16GB. It looks just like all the others. And worked fine at first (until I filled it past 16GB). You have to use an SD card test program, but it won't just tell you the truth. You have to run the 'write test' and when it gets to 16GB (or what ever, short of 64) if the test stalls or chocks there's your answer. The card thinks it's 64GB so when it gets full, it just keeps right on going, overwriting and corrupting everything. Now windows will sometimes say a newly connected drive or card needs Formatted when it DOES NOT. DON'T fall for it. Just reconnecting should fix it, usually it was just wanting a drive letter. BUT an unexpected cry for Formatting can be a counterfeit card warning as well.

That happened to me with a supposed 2TB thumb drive. I'm not sure how my dad fell for it, let alone me. That caused a mess.
