If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct driver for your card reader.
Another very common cause of an unrecognized SD card is a very simple one: a dirty SD card or a dusty card reader.
Start at the top of the list and work your way down until you find the fix that works for you.
Or clickthe drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
If your card still isn’t working after updating your drivers, move onto Method 2.
Select this then click Driver then on the Disable, acknowledge the popup, then back at the driver screen click on the Enable and its popup — the SD card now appears as it did previously & is accessable.
Don’t know why this works but it did for me.”If you’re not sure how to do that, refer steps below:1) On your keyboard, press the Win R (Windows logo key and R key) at the same time to invoke the run box.2) Type in the run box and click OK.3) Expand category “Memory Technology Devices“.
But once you’re in the BIOS, it shouldn’t be too hard to find the ‘on/off’ switch for your card reader.
