Not a real problem with adf-Files. But it's not a good idea to try "floppy emulation speed" to 800% when you make your first steps with real hardware using #GreaseweazleV4 under #WinUAE :)
Took a few moments until I realized the problem. Now it formats without any problems.
#RetroComputing #Amiga

I've gifted two Christmas parts to myself. One is the #GreaseweazleV4 #Amiga USB floppy adapter. The other one is the actual RP2040 version of the #ZuluSCSI. First usage is the #MacIIfx. If it works fine maybe another one for the #A2000 after.
Background: My wife would never ever gift electronic to me, it's not her world.
