SMART are diagnostics and monitoring software built into most modern discs. There are tools to view what it has discovered about the disc. However, from what you are saying, I would say that the disc is fubar and does need to be replaced. Some of the more important information SMART can monitor about the disc:

  1. Read Error Rate
  2. Reallocated Sector Count (a critical metric)
  3. Seek Error Rate
  4. Temperature
  5. Uncorrectable Sector Count

SMART stands for Self Monitoring And Reporting Technology. If SMART says your drive has had it then the only fix there is is to get a new one.
