Disk2FDI will do the job m8... isnt there a doc file with it? or you can type DISK2FDI whilst in dos and it should display the required codes n stuff...
i will check it out in a bit
C:\DISK2FDI /S B: DEMO
Will create an ADF, ST or IMG image of disk in drive B to the
DEMO.ADF, DEMO.ST or DEMO.IMG file, depending on the kind of disk you
have inserted. The kind of disk is detected automatically.
What i do is have the amiga disk and a blank pc disk inserted and i do this:
C:\DISK2FDI /S C: DEMO
it will read the amiga disk and save the adf file to drive C:
then after its finished you reset and boot back into windows... go straight to drive C: and there should be an adf file all ready for winuae/fellow etc...
hope this helps!
