Hardware SD2Vita - Free Space wrong?

[Hephaestus]

My Vita reports 14gb free space on a 400gb microsd.
Windows reports 179gb free space on the same microsd.

All i did was flash zzblank.img, formatted to exfat and copied everything over from my 200gb microsd.
Does anyone know what went wrong?

Did you actually set up the Vita to use it? You can't just put it in and away you go.

Nevermind, just noticed you were coming from an older SD card so you must have.

use 64kb cluster, that would fix your issue.

After a bit of googling i came upon that bit of information, too.
You are absolutely correct.
