How can I fix a microSD card that is not being read or recognized by phones or computers?

Anthony Smith June 18, 2011

I have a 16 GB class 4 SD card that came with my DroidX smartphone. I was resetting the phone and in fear of my data on the card being lost, I pulled it. Not during boot, but the phone was on.

Now the card is not noticed at all by any Android smartphones or computers. But my Blackberry Curve sees the card and says there’s a problem and it can’t read the card.

Is there anything I can do to make this 16 GB card useable again?

      You need to format your card in your phone as it creates compatibility issues when formatting in PC.

      Try formatting it in PC and then formatting it in your phone so as to make it detect in your phone.

      a. Click Start and go to Control Panel.
      b. Click Administrative Tools and then click Computer Management
      c. When that window opens you can click on Disk Management and find the device in the drive viewer.
      d. Then you can right click on the drive and select Format and see if using this utility from the Disk Management helps resolve your issue.

      Have you formatted your card in right format.You must format your card within the tablet itself so as to prevent any such compaitibilty issues.

    were you able to fix your microSD card or read it to backup your data? If yes, how did you do it?

      since this is a different scenario from the question posted above, I recommend that you submit a new question.

        Tina, Ous question is relative to the main question. 
        How can I fix a microSD card that is not being read or recognized by phones or computers? When I check it on my phone it says that the MicroSD has a password. I tried using an explorer software on my phone but then it would not detect microsd card as well. I tried removing it from my phone and using it in a card reader but it was not recognized by the computer. PLEASE  INSERT A DISK in the driver.  PLease help.. Ous did not repost...

          I'm afraid I don't have any other suggestions than the ones posted above and you are unlikely to receive more/new suggestions in this comment thread.

          The thing is, at some point hardware is simply broken and can not be fixed.

          You may still be able to have the data recovered by professional services. However, that is quite expensive.

          Thanks Tina, I really appreciate it. I've already come to terms with the fact that the info is lost. It's just that this is a very common problem with microSD cards and it's very difficult to find solutions online. This was the only thread that I could find with hours of web-crawling with different keywords. Again, Thanks for your quick reply. You may want to add email notification to this site. I honestly forgot about making this post. I just ended up googling myself and this came up.

          the problem of email notifications is something we're working on and I know it's an unfortunate situation right now.

          We have had some serious issues with comment notifications and decided not to turn them on again until these issues are fixed.

    Click Start and then Run. Type cmd and then click OK. Type the following:

    chkdsk [sd card drive letter] /r
    this will Scan for and attempt Recovery of bad sectorsor

    chkdsk [sd card drive letter] /f
    this will Automatically Fix file system errors on the disk

    Hello, you could try reformatting the card with software made specially for formatting sd cards such as the following:

    Once reformatted, insert the card in your phone and hopefully It will be fixed.

    Another program that provides results if Flash format.  It is a paid program but you can get a trial:
