Why need to change SD card serial number? To check or read the serial number on your storage device, you can execute the command: dir in the Command Prompt window. The function of the SD card serial number is similar to the fingerprint of persons: identify a specific item. So they may contain letters and other typographical symbols, or may consist entirely of a character string. Instead, it is determined by the data and time on the real-time clock on the current computer at the time when you format the hard drive.
The serial number does not need to be strictly numerical. Besides the SD card, other electronic data storage devices such as USB flash drive, memory cards, hard disk drive also have such a number. A serial number is an identifying code assigned to the hardware during the creation of a file system for unique identification and licensing.
