I work for Adafruit Industries LLC. We build microcontroller boards that use the Microsoft "UF2" bootloader for updating firmware on the boards. See https://github.com/Microsoft/uf2 and https://github.com/Microsoft/uf2-samdx1 for details. This bootloader presents as a simulated USB FAT drive, with a few fixed files. Copying a .uf2 file to the drive will update the firmware on the board.
AIDA64 somehow interacts badly with the UF2 drive. Trying to read or write a file to the drive when AIDA64 is running will cause Explorer to freeze up. Some reports:

We can warn our users about this, but it would be nice if AIDA64 did not cause Explorer issues with these drives.
Let me know how we can work together further on this. Thanks.
