I would certainly make sure you have backups as soon as you possibly
can - I have had this in the past and although the disk may run for
many weeks throwing periodic smartd mails or popups at you, it could
fail in a bad way at some point which may be sooner rather than later.

In my case I took a backup as soon as the errors began, and no more!
If the data gets corrupted and then you back up corrupted data it
could lead to problems (understatement).

Again what I did was get a new drive and then did a secure erase on
the drive that was failing (it still was working enough to be able to
do it!) - and then replaced the drive, and partitioned the new drive
from scratch. Then installed a new system on it, before retrieving the
backup data and getting the system operational again.  Total time from
first smartd impending failure messages to new system was a week -
however YMMV.

Good luck.
