I made a disk image of *the whole card' (not just the main partition) using Disk Utility, and then flash the disk image to the new card using the free Etcher app.īoth tests produced new cards that worked flawlessly on my Switch.

Yes, you can clone a perfect facsimile of your microSD, but trust me it isn't really useful. My guess is that firmware 6.0 employs a stricter data integrity verification, rendering this method no longer viable. Now I have a card full of games that I cannot access.

So I did this and put the new card in-no error code this time! Hmm, my saved images were missing from the album though.

My Switch showed an error code 2016-0247 ('unable to access microSD card') as soon as I got to the Home screen. I tried copying the Nintendo folder a) directly between two cards, and b) through an intermediate HD.
