my sd card s working in my camera but it aint showing n my laptop's internal sd card reader

Hi,

Have you check in File Explorer if it's listed?
- Click Start then Computer or My Computer and see if it's listed as a Removeable drive.
- If it's not listed remove the SD card first then uninstall/reinstall the card reader driver.
- Go to Device Manager and uninstall the Card Redear Driver and reboot your laptop.
- It should reinstall the driver automatically after the reboot but if it doesn't, download and install the latest driver from the manufacturers site then test if the SD card will be read or not.
