Hello! After unmounting, cleaning and remounting the drive various times unsuccessfully I decided to buy a new drive at winecountry. It's not cheap but it fixed the problem. Now everything works. I have 2 Prophets (1x Prophet 2002 256K with the new drive and 1x Prophet 2002 plus 512K with the original drive). If I format a floppy with the first, the second says iF (incorrect format?) when I try to save something on it. But if I save a disk in the first, the second can read it without problems. Then I noticed that there are some disks that are read with no problems with the new drive but not with the old one. And other disks behave the opposite! Mysteries... A little OT question: did Sequential offer an own sample library? I only have 2 original Sequential disks (1986, for the 512K version: #875-01EX REV A and #875-02EX REV A, unfortunately they don't work!). Are these the only disks ever made by Sequential?

Today I got an used 2002 and unfortunately I have problems with the floppy drive. But istead of getting the "nD" message I get again and again a bliking "Lh" message. If I i.e. choose to format a floppy I put into the drive, the drive gives a spin, the red light lights for 1 second or so and I get that "Lh" on the screen. > > >> > > >> Any idea? > > >> > > >> Thank you! > > >> > > >> Edo > > >> > > >> > > >> > > >> --- In prophet2000@yahoogroups.com, Rob Miller <dpc318@> wrote: > > >>> Well, I replaced the 7406 buffer chip between the floppy controller and > > >>> the drive, and while the individual logic is better on the chip, it > > >>> did not resolve my "nD" issue. > > >>> > > >>> My drive seems to be spinning all the time while a disk is in it, > > >>> with the red LED on.
