I have a SDHC/SD memeory card used in my digital camera. It is corrupted due to some virus I think, now it shows only 32MB of memory. I want to recover data from it but when I put it in my computer it says “First format the disk.” Well, that will erase my data. What do I do?

    it may be happen that virus have changed the attributes of your file and folder to hidden. so, currently they are on the card but you can not see it. to recover this file you can use USB show which change the attributes to Normal and recovers the files and it is run without installation. you can download it at

    You can try something like testdisk and see if anything can be recovered.

    I think you may need a Partition Recovery Software. This one may recover the missing data.

    Follow these user's guides. Just use Linux or OS X and Linux or OS X will resurrect your SD card. If you want to recover the files before format the SD card, just use Recuva for Windows and use PhotoRec for Linux and OS X.

    I use OS X, my pen drive was died by a virus and I couldn't format, but when I switched to OS X and I was able to resurrect my pen drive, but for the worse, I lost the files because I didn't use PhotoRec before formatting.

    Sounds like your SD file table has been corrupted. Probably from improperly ejecting your card while files were being held in temporary memory. You always want to do an eject procedure (properly powering down) of your UBS or flash media before disconnecting it phystically.

    Only real way is to get some file recovery software or try using a Linux live cd to see if can still see the files.

    If you are sure that virusis the only problem,then you Insert into Linux OS.Usually virus would be dormant in Linux OS.Then copy all the files you needed and formatthe drive.

    1) perhaps you can make an image with imaging tool
    2) mount this image and see what you can do there.

    See if testdisk can fix partition table

    First download Fedora Security Lab Linux distro.

    Then install it onto your pen-drive using any other uninfected computer.
    Then boot it to your PC. There you will find many applications to recover your data. Use another pen-drive or partition to store the recovered data.

    At this point, I am afraid the only option you have is to format your card and try recovery option. Just make sure you computer is not also infected...

    My favorite method of dealing with randomly malfunctioning SD cards is through two tools: MiniTool Partition Wizard and Gparted. Both are excellent options for managing partitions, although Gparted is so robust at handling SD cards that it makes Partition Wizard more of a backup plan than a primary solution. Aniket's suggestion looks good, although I have no experience with it.

    Gparted, unfortunately, requires that you burn it to either an SD card or a USB drive. It will also require that you have some method of connecting the SD card to your computer. If both methods are available to you, then you will simply boot into Gparted and if your drive is recognized, then you can reformat it.

    I suggest using LiLi Creator to make a Gparted live USB, if possible. Justin Pot wrote a great guide on how to use Live Linux USB Creator.

    Otherwise, lacking the correct equipment, try Partition Wizard.

    If it asks you to format, it will delete everything. I would try using a different OS, win7 is usually pretty good but sometimes another perspective (if you will) is better.

      If you're extremely lucky, you can salvage (usually very little) bit of data using Recuva. Format only if Gparted fails.
