Introduction
An SD card’s ID number, also known as its unique serial number, is a vital piece of information that distinguishes it from other SD cards. It is often used for identification and security purposes. This article will guide you through the process of reading this ID number using different methods.
Methods to Read the SD Card ID Number
1. Using the ‘sdcard’ command (Linux)
This method is applicable for Linux-based operating systems.
sudo sdcard -i /dev/sdX
Replace ‘/dev/sdX’ with the actual device name of your SD card. This command displays information about the SD card, including its unique ID number.
2. Using the ‘fdisk’ command (Linux)
Another option available on Linux is the ‘fdisk’ command. This method involves checking the partition table of your SD card.
sudo fdisk -l /dev/sdX
Look for the ‘Serial Number’ field within the output to find the ID number.
3. Using Disk Management (Windows)
For Windows users, the Disk Management tool provides access to SD card information. Follow these steps:
- Open the ‘Disk Management’ tool (search for it in the Start menu).
- Right-click on your SD card and select ‘Properties’.
- Go to the ‘Hardware’ tab and select your SD card.
- Click on ‘Properties’ and then the ‘Details’ tab.
- Select ‘Device Instance Path’ under the ‘Property’ dropdown to find the ID number within the value displayed.
4. Using Software Tools (Windows and macOS)
Several third-party tools designed for managing and analyzing storage devices are available for both Windows and macOS. Some popular options include:
- CrystalDiskInfo
- H2testw
- SD Card Formatter
These tools typically provide detailed information about your SD card, including its unique ID number. Check the specific instructions provided by the chosen software.
