Suddenly, all my MSF files were empty!
Thunderbird was closed when my laptop crashed and i rebooted it. When I next opened Thunderbird, it turned out that all of my Mail Summary Files (*.MSF) had been replaced with empty files (0 bytes) and the current date/time. As far as I could tell, none of the other files on my hard disk were damaged in any way. While I was able to restore them from backup, I am trying to figure out what caused this to happen in the first place. Any ideas?

Anti-virus software is a common cause for these kind of problems. These are some generic suggestions to avoid problems with anti-virus software.
Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. http://kb.mozillazine.org/Profile_folder_-_Thunderbird
Don't let your anti-virus software scan incoming and outgoing messages.
Don't let your anti-virus software scan attachments.
Don't let your anti-virus software intercept your secure connection to the server.
Remove any add-ons your anti-virus software may have installed in Thunderbird.
