I was using a MZ-R30 and it put a nice dent in the corner of the case, 
which is still there. I actually dropped that one hard on 3 separate 
times. It seemed to always hit the same corner.

To be fair I had correspondence with one person who dropped a Portadisc 
off a table onto a hard floor. That had to be sent in for repairs, even 
though no external damage was evident. Would not play or record, but did 
not damage disks. I never heard back what was found internally.

All boils down to regardless of type of equipment it pays to be careful.
