Yes, this is a warning you REALLY should act on. I had this happen this past weekend on an old desktop unit - SMART message of impending failure. I removed the bad drive and mounted it temporarily in another desktop along with a spare HDD. Then I used a cloning program to clone old (bad) to new. The cloning program took more time than usual because it kept running into bad sectors on the failing drive, and I had to tell it to ignore those problems and continue. Eventually it did complete the job. I checked the replacement containing its clone copy using CHKDSK a couple of times and it had no significant errors. When I mounted it back in the troubled desktop in place of the failed HDD, it worked perfectly and my daughter is using the machine right now.
The whole point of SMART messages is to warn you BEFORE the failure progresses to really bad conditions. That way you usually have time to make your clone or whatever to recover all your data etc., before the failing drive cannot be read at all. So fix this problem NOW!
