The one mechanical problem that I've seen in a fairly small number of 1571s is 
when the bit that normally flexes as the head assembly is opened and closed 
actually fractures on one side.  That springy bit being broken would tend to 
have the effect of cocking the upper head at an angle,  which might account 
for the munching of the media.

They have alignment issues much less than 1541s because the 1571 typically 
includes a track zero optical sensor to tell the drive electronics when it's 
there so you don't have that constant hammering going on.
