Detecting shoe shining with modern libraries?

[Michael Loftis]

New drives are really quiet.  Not to mention some new libraries (like our 
Spectra T50) bury the drives in the middle of the library so you can't 
really hear the mechanism working like you can older libraries with louder 
drives.  Desktop units you can still pretty readily listen to and tell when 
they're shoe-shining, but as far as libraries go, does anyone do anything 
other than just do their best to listen?  That's what I've done 
for...well...ever but I'm beginning to wonder if there's a better way.
