speaking of floppies and floppy drives....I just purchased two Teac external floppy drives...one for my computer and one for the DKC 850.....both are having trouble reading (all of a sudden)...I get a message that they need to be formatted when I know they contain MIDI files....I've been using standard off-the-shelf floppies for ears with the DKC500 xrg with no problem....about 0.001% of the time, I can disconnect them from the USB port and they will read correctly but, this is a crap shoot at best....anybody else having trouble like this???
