Gosh guys! How about the easy route?
Just Open System/Storage/DEVS/DOSDRIVERS
and grab the PC0: icon and drop it into: System:DEVS/DOSDRIVERS
and reboot!
thats it! you will forever be able to read and write PC floppies by simply going to the Workbench menu and selecting FORMAT.
oh.and put tape on the disk if it is the 2 holes ones.......cover the one that has no switch. Put a piece of paper and tape.as tape alone may not be enough.
