Andrea,

I don't know whether the SD1 hard disk is FAT16 or FAT32. I do not think it is FAT16 because FAT16's partition size limit is only 2GB. SD1 comes with a 6GB hard disk so it has to be something similar to FAT32. In any case, I do not recommend connecting the HD directly to a PC. It's much easiler to use the Ketron File Transfer software available for PC or Macintosh computer.

You can manage the SD1's hard disk using the Ketron File Transfer software (available free on Ketron's website) along with a $20 PC-to-host cable on a PC or Macintosh computer . The Ketron FT software is a very easy to use GUI software that allows you to transfer any type of files (midi, wave, sounds, registrations, user settings etc.) between the SD1's hard drive and your PC. It also allows you to create, rename & remove directories (folders) easily.
