    Internal SD card reader not recognized


    Hello

    This is an old problem.

    I got an internal all in one reader. The USB port is working but the sd card is not recognized.
    When I put a SD card in it, the PC is do run and try to read it but no error message is shown.

    In the disk management, the E\ drive is set to SD card, but nothing do appear in the volume allocation

    In file explorer, I tried to format the SD card. When I insert the card, the system is looping, trying to read it.

    I tried to
    - removed it and reinstalled
    - update the driver
    - Win diagnostic and repair error

    Any idea?

    Post a screenshot of Device Manager. Card Readers can be under USB devices and may have a Yellow ! if the driver is not installed. It is possible that the SD card reader is bad, especially built in. USB type devices also fail.

    Can you explain this?
    An internal Card Reader would not connect via USB. Only an External USB Card Reader would. An internal card reader would connect with a cable directly to the motherboard and not USB.
    If an external USB Card Reader, be sure to plug the USB cable/connector into the Back USB ports of the desktop computer and not the Front or thru a Hub. As these ports diminish the power and have a hard time connecting a Mass Storage device, like a card reader.

    Internal Laptop/PC SD Card readers are usually a USB device, connected to a USB hub, very common. So is the internal Camera on my Laptop.

    The usual problem is poor contacts. I clean the SD card reader by blowing out dust and inserting a small piece of card dampened with alcohol. The SD card contacts get the same treatment. Some of my SD Cards seem to have more of a problem than others.

    You can also shine a torch into the slot and check on the contacts, are they in line, same height, etc.
