Hacking vWii and WiiU USB disk?

[Muyfa666]

I understand that vWii and WiiU backups can not share the same USB disk. Are there any way around this - using passive powered disks, or do I simply need two different disks that have external power supply?

i believe you can set up in vwii game loader (USB loader GX, configurable usb launcher, wiiflow, etc... Dont ask me which one it was, can't renember) the usb port to use for a hdd.
So in the top 1 (i believe it was usb 0?) you put the wii u hdd
And in te bottom 1 (i believe it was usb 1?) you put the vwii hdd

*Ok just readed something about it and seems you need the alt version of d2x for the second usb port to be enabled.

Tough you need external power supplied hdd's
Not sure if it will work tough, i just switch up the hdd's when needed
