George,
If your desktop computer will recognize your slimline hard drive, connect it to your desktop, then copy the floppy disk directly to the hard drive.
Next, connect the hard drive to the PSR-3000, then insert the card in the front. If you will be copying style files, select USER on the 3000, then tab over to the hard drive. Select (highlight) the styles you wish to copy to the Flash card, press copy, then tab to the flash card and press Paste. It's that simple.
