Here we are. I finaly found someone to help me out with a PC to dump a formated empty Studio 440 disk.
Here you can find a empty Diskimage for the Studio 440 plus the CFG file attached.
I used the CFG file from the Prophet 2000 folder, what works and put it into the ZIP.
Copy both files to a SD card
Disconnect your Floppydrive from the S440 and connect the HxC instead. (1(coloured line) of the Floppydatacable must be on the right side of the connection. Set the jumpers of the HxC to ID0 or ID1 (On my original floppycable, it was ID1. After exchanging the cable, it was ID0)
If you got a SCSI drive (zip etc) to the 440 connected and get it to work, it´s faster of course,
but I really had problems to get the Scsi bus working. Finaly i found out, that you got to reset the SCSI drives (Disk menue) after switching on the S440. Then you get access to the connected SCSI drives.
The plus of using the HxC is, that you can have backups on your computer. You can´t make Backups with the SCSI on the average computer. If your SCSI medium breaks up , you might be f...ed.
So, even if you got a Studio 440 with a broken Floppydrive, it´s pretty easy to dump the disks with the HxC software and go with the HxC. Read and save them to the SD card and you´re fine.
Thanks again Jeff, for this good piece of Hard- and Software!
