I'm in the middle of using Toast to make copies of previously burned Data DVDs and suddenly Finder decided it won't mount one of the discs! The disc was burned using either Toast or Disk Utility (just like the others I've been copying) but it won't mount using either my internal SuperDrive or my external Lightscribe drive. Running OS X 10.7.3 with all the latest updates...

I realized the disc in question was actually not burned using software, but using a hardware DVD burner. The problem was user error—the disc had not been finalized after recording. Finalized the disc in the hardware, and problem solved.
