I have the same problem on my external 800. I was copying a ton of disks to my Plus's external drive and after about cranking through about 100 disks, it starting making a weird crunching noise as it ejected. Didn't sound good at all. I let it sit for a few days with the intention of opening it up and looking to see if anything was out of place. I totally forgot about it a popped a floppy in it. When I ejected the disk, it struggled again, ejected the disk after making a weird noise, and is now stuck in the eject cycle.
