Hello, this is my very first contribution to devialetchat - i've been following for some time now.
Modern SD(HC) cards have quite huge capacities and cannot be formatted in the old FAT-style, which seems to be restricted to 4 GB volumes max.
The trick to make them work in my Expert 200 amp, was to resize a 16GB SDHC (mentioned before) card via Windows command line tool "diskpart".
In the end it became a 4GB (active) volume, wasting any space beyond (but dp_cfg.txt is tiny compared to 4GB).
The resulting volume then can be FAT-formatted e.g. by right clicking in Windows Explorer.
Not a very comfortable way to go, but worked perfectly and the card has more modern flash technology compared to smaller, rather old cards.
For detailed instructions, please see https://www.instructables.com/Format-USB...not-FAT32/
Best regards, Ecki
