This option requires a tape cartridge in your tape device and will scan your system for valid tape devices and try to find out the one to use with KBACKUP. This should solve the problems of all those people who tried using KBACKUP with a rewind-on-close device. After examining your system, KBACKUP will prompt you with a list of usable devices.
Caution: This will write to the tape and overwrite any data on it!
