   I had tested using a coworker's iPod Nano, and found that it ignored
 a mode sense(10) command (apparently without erroring - it returned
 0 bytes of data), but did respond to a mode sense(6) command (although
 the page 6 data was all zeroes).  Even more fun was the Sansa c140 I
 have - it accepts the mode sense(10) command, but returns the data
 in the mode sense(6) format.  This was interpreted as a 600+k sector
 length and results in a panic when it attempts to get the disklabel.
