Thought I'd resurrect this thread as it is the only thing that shows up on Google for Denon Minidisc "Mech Err 1" - I have the same drive in my Denon DMD-F100. After several rebuilds I finally found the problem with mine was that the clutch gear was seized solid. Even though the limit switches on the load/eject mechanism were working fine, it seems like the player still relies on a certain amount of clutch slip at the ends of its travel. With no slip the torque from the worm gears tries to push the drive apart and jams it solid. I dismantled the clutch to free up the plates and now it is loading and ejecting perfectly.
