Hacking psp vita memory cards issue

[viper2500]

I'm using a 256gb sd to vita memory cards. The Vita said I only have 80gb left but when I connect my Vita to PC using Vitashell it said that I have 155gb left on my computer, How do I fix this?

Wrong cluster size most likely, copy everything off to a computer then format it as 64kb cluster.

you need to format with 64kb allocation size for sd cards 200gb and up instead of default.
If you already did this and it is still mismatched size delete some stuff from your sony mem card that you already transfered over to sd card otherwise it takes up double space in ux0.

I had the same issue when I upgraded sd card size to 256gb a few weeks ago.
64kb is the fix as said.
