The "warning" status you are getting when you read the SMART status from your disk is basically useless. Any application that can read SMART status can choose to rate the drive however the authors see fit; it is an arbitrary rating that doesn't necessarily indicate a problem. Look at the actual data values reported by SMART. In particular, check your "Read Error Rate", "Reallocated Sector Count", "Seek Error Rate", "Power-off Retract Count", and "Current Pending Sector Count". (Those are attributes 1, 5, 7, 192, and 197, respectively.) That should give you a pretty good indication if your drive is failing.
Remember, if SMART reports that your drive is failing, its definitely failing. If SMART reports your drive is OK, it may or may not be failing. SMART can only conclusively determine failure, not fitness.
