A secure digital card, or SD card, is a portable electronic data storage device used for storing digital information. A WORM SD card is a special SD card that utilizes the WORM technology in which digital information, once written on the SD card, can no longer be altered. The main card slot needs a regular SD card while the second card slot requires a WORM SD card. Cayton explained that the WORM SD cards do not need further formatting because such act will be considered tampering with the WORM SD cards and will affect the operability of the WORM SD card." Pure logic dictates that if the VCM runs on a "formatted" WORM SD card, then the WORM SD card is no longer write-protected.
