Device with major 22 and minor 2 is /dev/hdc2

$ls /dev/hdc2 -l 
brw-rw---- 1 root disk 22, 2 Feb 22
                       ^^^^^ 
                   major  minor 

You would have to already know that the error message is telling you
device numbers, and to connect these to a particular device.  I
finally guessed this when I had similar disk errors. 

My reason for jumping in is to ask: Will somebody please tell me
What the 16 in 16:02 means?
