    If you have an earlier version of an SD card reader, you may not use the SD-HC cards with it as they are “high capacity” SD. I found that out when I inserted a (older & specifically) “SD” card my reader works fine but the “SD” cards sold presently are of the SD-HC technology and not backwards compatible. A way around this is to purchase an external USB card reader that is SD-HC and off you go.

    I am facing a problem in detecting memory card through a MICROSD adapter in a

    computer. The memory card is connected to an ATMEGA32 microcontroller which

    in turn is again connected with a RS232 port to connect with the computer using

    MAX232 receiver. So when I am applying power to the Microcontroller the computer

    is not able to detect the memory card. Is there any driver file necessary to install so

    that the PC is able to detect the memory card. Please give your suggestions

    regarding the problem.

      Yup, a driver is required. You will need to write a driver that tells your computer how to connect to your device out there (the microcontroller) and communicate to it that it wants to access the MicroSD attached to it. Since you are running a custom device, you need to write your own driver to be able to access it. The development tools available for the microcontroller should provide help in the process required to create this driver.

      It’s kinda like the back in the 90s when custom drivers were required to run tape drives off of floppy disk controllers…

      I have checked in the internet but has not able to found the driver

      file. Can you tell me some links where from I can download the

      software. Its very urgent. Hoping to get your response.


    • Bruce Epper

      I am working off of the assumption that you have programmed the microcontroller to perform some kind of function. The computer has no clue what this function is. It is your responsibility to WRITE the driver to tell the computer how to communicate with the device. You cannot download the driver, you have to MAKE the driver yourself.

    I have Windows Vista,

    my internal Card Reader works occasionally.
    but I get frustrated, I have no clue how get it to work.

    I restart the computer multiple times. occasionally it just works.
    and after a few months it doesn’t.

    no matter what card I insert. SD or other types, it won’t respond.

    I’m going to smash it soon.

      It might be the case that the reader slot is faulty.Contact the manufacturer for support and if under warranty replace your laptop.

    Sometimes when I open an e-mail on a HTC phone it downloads then gives me the option to save on my SD card and I tap that and it says saved to a SD card and I have no clue where its at or how to find these pics and e-mails. Can someone help plz

    • susendeep dutta

      You can try clearing data for the app you use to fetch emails,move the app to sd card if possible and try to fetch all the mails.

    my card is not detected by my pc but works perfectly fine on other pc and even my phone. how can this be solved???? 


    Hello, I guess the only thing you could do is to get a memory card that is compatible with your pc when you get another one.  Is is that the card is not compatible with your system? or is it that the card is not recognized?  Or Does it give you errors when you try to read it?

      Unfortunately, memory cards to break and unless you want to invest into a professional recovery service, sometimes there is nothing you can do yourself.

    is there not a run command for this?

    I have a MSI Wind netbook with a SD card slot and sometimes it wouldnt recognize my SD card either. All I did to “fix” this issue (which seems to be an ongoing issue) was to 1) shut down the computer. 2) Pull out the battery in the MSI Wind netbook. 3) Hold the power button down for about 10 seconds to drain all residual power. 4) insert battery and restart.

    Now if this is a desktop computer, you could try powering down the computer, opening it up and disconnect the card reader from the motherboard (connects to a USB port on the mother board) and then power it up without it being plugged in. Once its done booting, shut it down again and reconnect the card reader back to the mother board. This might “reset” it and get it working again. I hardly doubt its a corrupted data/bad SD card problem, but a hardware/software issue. Thats just in my personal experience however.
