Is my USB drive dying?

Logwatch says:

--------------------- Kernel Begin ------------------------

And in /var/log/messages I see:

This is both my backup drive and where my repos are located.  So given 
this is the time of the 'big sales' is this drive failing and it is time 
to buy a replacement?
