Thanks all for the info!
I will also try the egroup.
But the communication between the hard drive and the PC is solved by a cheap converter the only drawback is that i have to remove the drive and mount it in the PC. The files are actually copied well. My probleme is that the synth can't see other directories but the one it creates after formatting. It is not enough to copy the files to this directory but I had to edit the *.mng file because the 8000 also renames songs if i copy them normally from floppy drive and saves the original filename into the .mng file next to the filename it created.
