iv a external HD floppy drive which works in both modes 880k & 1.44 regardless of what OS is being used,so it works also under OS4.0
iv also yet to test the internal HD drive,will post results when iv more time.
one advice i can give is that if you have a HD drive which was working in both modes & then starts to give read/write errors which may be down to faulty read/write heads is to buy another drive of almost the same type & change over the PCB to the new drive as sometimes the fittings of the PCB is the same.
this will give you new read/write heads & keep your HD mode on the floppy drive.
i also notice that some rare floppy drive can also have motorize eject,you just have to know how to enable it and find the right parts.
