anyone know anything about #greaseweazle ?

i just got a V4.1 i'm trying with two amiga drives, i have --drive=0 option, both drives properly spin and seek (if i force a cylinder or use the clean function), but any read operation returns Command Failed: GetFluxStatus: No Index

i'm hoping the greaseweazle itself isn't the issue, still waiting on a pc floppy drive to arrive
