Hacking See and backup wii u flash drive data on pc.

I need to make room for updates but I don't want to delete and re-download games. If I move my games to my flash drive is there a way I can see the files, move on to pc, delete the games from the flash drive then later add the files back to flash drive to move back to my wii u?

Wii U uses a proprietary encrypted file system. As far as I know, there's no drivers available to make use of this on any OS. (There might be some experimental tools for basic functionality, but nothing that's designed for the end user.)

You'd also need the encryption keys, which are stored in OTP and/or SEEPROM.

In theory you could create an image of the flash drive, format the drive on Wii u, then later flash the image you made back into the drive. Can't verify that will work though.

IIRC the encryption method uses part of the device serial number in the key derivation, so that won't work.

Ouch. Square one again.
How about this: I have a broken tablet (touchscreen dead but I can still turn them on and connect to my pc to access files). Would the wii u accept that as a storage device?

Old versions of Android supported block device pass-through for the SD card. That is, it'd basically be an SD reader. (You can't access the SD card on the Android device while using this mode.)

Android 4.x and later no longer supports that; instead, it uses MTP. Wii U doesn't support MTP.

Even further back. Thanks anyway.

If you flash the image back to the same device, it should have the same serial and thus would work

OTP has SEEPROM parts, so OTP still would work.

I've done that with Win32DiskImager before and it reads data fine

It should still work as long as it's the same device. Though it is possible that formatting the drive again invalidates the old data.
