Create Emergency Disk

Select Create Emergency Disk from General menu and insert an empty 1.44M floppy disk in your floppy disk drive. After Create Emergency Disk, setup BIOS and boot from the emergency floppy disk to recover partition. We recommend you should Create Emergency Disk when you first run Partition Table Doctor. The Emergency Disk contains partition tables of your Harddisks. Backup is better than recovery!
