From what it says it looks like HD sentinal is predicting an upcoming failure. Not sure if that can be fixed. It is Reallocated Sector count that is the issue. Google and check if that is an issue. You might be lucky.
Maybe some expert here can comment on that.

I'd take a backup just in case!

Edit:
Looks like it is an issue. Take a backup.
