[BUG] SD image can't be loaded after pressing "Generate Empty Image" in the simulator.

[mriscoc]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

The simulator allows you to test some Marlin functions without having a physical printer. It is possible to simulate a SD memory card by loading an image file, the simulator itself can create an empty image by pressing Generate Empty Image button:

But, after the image is created and loaded an error is shown in the console: "Error: volume, init failed"

Simulator compiled and running under Windows 10 with the example configuration files from the configuration repository.

The image is generated correctly, it was tested with third-party software.

Probably better to file up in actual sim repo https://github.com/p3p/MarlinSimUI
Tried it in linux yet?

Unable to replicate at the moment will need to try on Windows though, make sure you are using the most recent version, delete both .pio in Marlin, and .cache that should be in .platformio in your home folder.

Turns out the issue was in Marlin and not the sim after all, although can't really blame it for the compiler on Windows messing up the bit packing.
