havent i met you before?just format it to FAT32 on your PC. Your switch already has FAT32 drivers. If you try to format it on your switch the switch will see the large drive (anything >32G counts as large) it will use their substandard exFAT drivers that are -done corruption. The default disk format tool on Windows won’t do large drives by default either so download https://rufus.ie/en/.
