Over the weekend, I made the move to use a flash as a repository (don't need no wires to repo!). Felt that needing 12 MB to store less than 2 MB was a little bit high.
So I figured "simple fix, I'll just reformat the drive from 32Kb allocation to something less, like 4Kb".
After 30 seconds of a single copy/ paste, the transfer was complete. Checking the size... accidently clicked "4096 kilobytes" instead of "4096 bytes".
