What's your backup plan? If you have an external HD, you can make it bootable via Carbon Copy Cloner and either run Classic off of that, or use it as a mirrror. Then, if something such as this happened again, you'd simply need to copy the Classic stuff back over (a DVD or iPod are other options for this).
BTW, RTFM means read the freakin' manual.
