Help after changing SD card

[Thatoneguy77]

Yesterday I bought a new SD card for my jailbroken Switch. I followed all the instructions in a YouTube tutorial (How to Transfer Mods to Another SD Card for Nintendo Switch (NxNandManager) and when I open Atmosphere it says it can't read the SD card. its a SanDisk 128GB SD

(btw images not mine but its the same error)

Do you get the same error If you boot to ofw and insert the disk when the switch is powered on already?

What I would do...
Test the card with H2Testw, if it checks out ok: reformat and put it in the switch:Just to check, if it works put the contents back.
