Strange problem while running DVDShrink

This past Sunday I made the mistake of opening DVD burner to remove a disc while DVDShrink was processing DVDFabDecrypter files on the hard drive. As soon as DVD burner opened the system rebooted after which all drives past the second letter drive was gone from the extended DOS partition. Luckily I had backup of all irreplaceable data, but more than a little time was required to repartition, reformat and restore data to those newly created drives. Has anybody else experienced such odd behavior with DVDShrink?
