florida guy, Since you are having bad sector problems with this drive, I would further Mark's recommendation in that you should run chkdsk /r several times (a least three times). If the repeat passes don't show new errors, then run it every other day for a week and see if new errors show up. If they do, don't wait. Replace the drive. If chkdsk corrects the errors, rerun the TI backup and get a good image (one without "ignore" errors in it). And, if you want my professional opinion, I would recommend you replace the drive now. I've worked on too many computers were the hard drive fails extremely quickly once it has reached the point where yours is at.
