Sequential circuits samplers

Hi!

I just joined this group. 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
