Are you using that in Wii U mode or vWii?
Wii U formatted drives are encrypted, only the Wii U can access them normally (there are special tools to read the files though)
WBFS formatted drives for Wii/vWii can be accessed (to add/remove games)...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
