I dropped an RL02 that had the only copy of some programs.  
When put on the drive, it vibrated badly, and the ready 
light flickered.
I loosened the screws visible on the bottom, and adjusted 
the centering of the platter visually.  I put it back on the 
drive, and the vibration was much less, but the ready light 
was still flickering.  I adjusted the platter a few more 
times and then the ready light was solid on, and I was able 
to read the files!

If the owner of the system know what i'd done in the middle 
of the night, they would have wanted my head!
