I have a 3TB drive in GPT, It refuses to use any other allocation unit other than 64K. I tested it mutiple times in GPT it stays at 64K no matter what i format it as, i switched it to MBR and it accepetted the change but when i put it back to GPT it still does 64K is GPT stuck at 64K allocation no matter what? It wastes a lot of space doing things in 64K.
