in computers with hex code (16 bit) the pc counts like this (0,1,2,3,4,5,6,7,8,9) (10=a)(11=b)(12=c)(13=d)(14=e)(15=f)
so if there a 4 bit hex code like fe9d it would decode to 1514913. so the reg right now telling you have 11 bad blocks or bits that need to be reassigned. the drive max count is 200.00. so there a small bad spot on the drive. if it starts growing then there an issue with the drive heads hitting the platter.

go to wd web page and start a rma most drives have more then one year warranty on them. why buy a new drive when all you have to do is pay to ship the bad drive back to wd. (ask for a cross ship so you can do a drive clone and move all your data to the new drive.)
