SD cards are solid state memory cards that are used in computers, televisions, digital photo frames, cameras and many other devices that benefit from a small form factor, removable, storage module. Most computers with SD card slots include the drivers with the motherboard drivers, but you might get into a situation where the driver needs installed independent of the driver package. The installation instructions vary between manufacturers, but the general process is the same.
Use the installation CD or driver download for the SD card reader if it comes with one. This is the easiest and fastest method of installing the SD card driver. Open the file, then click "Next" a few times to get through the installation wizard. Click "Finish" to complete it. Restart the computer and your SD card should be recognized. Continue to the next step to install the driver manually if this did not work.
Click "Start," then "Control Panel." Choose the "Add Hardware Wizard."
Click "Next" to start the wizard. Windows scans your computer to search for any new or improperly installed hardware devices. Select the SD card reader if it is found by Windows and click "Next" until installation is complete.
Choose "Yes, I have already connected the hardware" if the SD card reader is not automatically recognized. Click "Next."
Scroll to the bottom of the "Installed Hardware" list and choose "Add a New Hardware Device."
Choose "Install the hardware that I manually select from a list (Advanced)" and click "Next."
Choose "PCMCIA and Flash memory devices" or "USB Mass Storage Device," depending on the type of SD card reader you are using.
Select the appropriate manufacturer's SD card reader driver or choose "Browse" to point the installation wizard to the proper driver you have downloaded. Click "Next" until you reach the end of the installation process, then click "Finish."
