Is my hard drive on the way out?

Just ran Crystal Disk Info on one of my computers and its flagging up an error with the disk:



"Reallocated sectors count" seems to be the problem area in the SMART check

Haven't come across this before, is it a false warning or am I going to need to get it replaced? The hard drive is 18 months old so still under warranty.

Just ran Seatools and it passed the SMART check and Short DST, odd. Will do a full backup over weekend.
