Syncing files: THE SOLUTION

So after much frustration in trying to sync files on two flash drives, I finally discovered the solution: I had been ripped off. Yes, I bought my second flash drive on eBay, where the seller claimed it was 64Gb in size, but in reality, it was a 4GB drive that had been HACKED to APPEAR to be 64GB in size. The file sync programs I was using weren't at fault at all — they simply had no way of knowing what size the flash drive actually was, copied what files they could, and then got terribly confused as they continued to write data to places that didn't exist.

So the solution turned out to be surprisingly simple: caveat emptor — buyer beware. If you see a 64GB flash drive on sale for $10, you didn't get a deal. It's like a $20 Rolex. It's fake, and you'll be sorry. Pay an extra $15 for that in-the-box flash drive from Kingston instead of the no-name drive from China. Trust me. It's not worth the hassle.
