Nexcopy Releases Solution to Write CID Values and Write Protect Secure Digital Media

write cid value

Lake Forest, CA – December 7, 2022 – Nexcopy Inc., a leading manufacturer of advanced flash memory solutions, improved their award winning Drive Manager software to include advanced functions when writing to Secure Digital media.

Nexcopy includes two additional features when writing to Secure Digital media with Drive Manager software. The first additional allows the user to write specific CID values to the memory cards. The second feature allows the user to write protect the memory card so the device becomes read-only.

The two features are used to increase security of the content on the cards. The CID value is often used as a key code to encrypt content on a memory card. The CID value can only be read back through specific vendor commands and sits in ROM (read only memory) on the card itself. The CID value is a hexadecimal value and each card has its own unique value.

The write protect feature improves security by making the SD card read only. Using this type of configuration eliminates the ability of a virus or malware to spread via the memory card. In addition, write protected SD cards eliminates an end-user from deleting, formatting, updating, changing or manipulating the content on the Secure Digital card.

Greg Morris, President of Nexcopy, comments; “The CID field or Card Identification field are values written into read-only memory. These values cannot be changed, manipulated or copied and are key for security and encryption. By using our Drive Manager software to write the CID value of a card, we are providing a higher level of control and security for our customer.”

Morris continues, “The write protect function for SD card media is another feature to improve overall security to Secure Digital media. Creating an SD card which is read-only provides the content owner additional security to their intellectual property. Typically the card manufacture sets this configuration at the factory, but with our Nexcopy solution, a business may take control of their production process by enhancing these conrol mechanisms. These features have not been available for in-house production to the general public before and Nexcopy is proud to announce such a solution.”

The Drive Manager software is an award winning software suite which provides a long list of features and functions any business, organization or government agency can use to improve their production process. Some of these features include:

  • Six copy modes (copy, copy add, device copy, IMG copy and unique data streaming)

  • Read CID values and export to .csv file
