It is also generally not recommended to modify the CID of an SD card as it can violate the terms of use for the card and may void the warranty. It is important to note that modifying the CID of an SD card can have unintended consequences and may cause the card to be unrecognized by some devices. For CMD10, the driver returns a default of zeroes, as do all other unsupported commands. But in most Realtek drivers, only CMD9 and CMD13 are processed. It looks most of Realtek card readers support SD commands via vendors' extension to USBMS protocol working via USB. You would then need to write a program using the Arduino software development environment (IDE) to communicate with the programmer and issue commands to change the CID. Free Shipping OEM Change Cid Black Custom Cid SD Card Write/Clone Cid 16GB Memory Card for Navi GPS Capacity, 4GB 8GB 32GB 64GB 128GB 256GB 512GB Size, 15mm. To get CID you need to send CMD10 to SD card and get 16bytes reply. To use an SD card programmer with an Arduino, you would need to connect the programmer to the Arduino using a serial interface, such as the Arduino's serial port or an external serial-to-USB adapter. These devices are designed specifically for programming and modifying SD cards and can be used to change the CID, as well as other information stored on the card. To change the CID of an SD card, you would need to use a device called an SD card programmer. It is stored in a non-rewritable area of the card and cannot be modified by the user. The CID is a unique identification number that is stored on the SD card and used by the host device to identify the card. According to sdhc datasheet specs: CMD3(get rca) -> CMD7(choose a card) -> cmd 26(card responsd) -> then i send 19 bytes to D0 pin: FE, 16bytes new cid values, and 2 bytes CRC. im sending commands through SD NATIVE MODE(spi doesnt support cmd26). "It is possible to change the CID (Card Identification) of an SD card using an Arduino, but it requires some additional hardware and programming knowledge. im trying to write CID to the sdhc card, i have a chinease cards which allows me to send cmd 26(write cid). I was looking for a question to test out and so I tried your question and got the below answer from it:
