[kwlug-disc] bad drive sectors

[Insurance Squared Inc.]

Getting the following in one of the bigger drives on the machine I use 
for backups:
Nov  4 15:24:49 ns2 smartd[1510]: Device: /dev/sdc, 39 Currently 
unreadable (pending) sectors
Nov  4 15:24:49 ns2 smartd[1510]: Device: /dev/sdc, 39 Offline 
uncorrectable sectors


Is this something I should try and fix?  Or is the fix a new drive?  
Don't want my backup machine going bad!
