NAND Drive not present despite being mounted

[MegAmi24]

I've dumped, mounted and selected my NAND drive, but when I try to find my SD key, the log tells me it isn't present. I've selected the drive multiple times and it hasn't worked. I'm using the latest version of the tool.

Try this

Works for me
