Entourage damaged database error happened twice in 2 days. Possible drive problem?

I have gotten a "corrupt database" error twice in 2 days on Entourage. I am wondering if it might be a sign of a bad or failing hard drive. I wouldn't be concerned too much normally but you would not believe the bad luck I have had with the new MacBook Pros. That and:

I have been using Entourage for years. I have never had any errors from it before 2 days ago when I received and loaded all my software onto replacement uMBP #5 (long story) via Time Machine. This is the third time i transfered everything using time machine and it has always worked fine.

Am I just being too sensitive?

Please no advice to switch to mail. I do very much prefer Entourage over mail and do not wish to switch.
