    How to recover Unallocated memory of SD card

    I have a small problem with a 4GB SD card.

    I formatted with my phone and how bad surprise, I missed 2GB. I inserted on the computer, I do "right click" on My Computer > Manage > Disk Management! and there it appears. Yes but there are 1.9GB healthy and Unallocated 1.89GB. How to recover the non-allocated. If this is possible of course. I was told to do: (convert:/fs:ntfs) on command prompt but still the same.

    Simply by right-clicking it on the explorer and formatting. Or you can remove the allocation, select it and reallocate, and format.

    Unable to delete. Is it possible with some software?

    The evolution of standards in SD does not help things. Some players do readers recognize FAT (16), therefore limited to 2 GB. If so your camera, 4 GB you might not be able to use it.

    Re: How to recover Unallocated memory of SD card

    And if I found a device that supports 4 GB cards?

    I say this because I found a log allocated to me what I wanted, ie everything except what is listed above. Result: Unable to return because Windows told me that this part was not allocated "or something like that", so that he could not open it, or the format that I could format it with the Software. I ended up with two sectors: one, and some 600 Mb and the other the rest of the card. But I could not do anything with because not dedicated.

    So I reformat, to see (at the point where I was) and here I am left with two parts of equal capacity. That is why I tell myself that I should format it with a device operating in a 4 GB card.

    If anyone knows where to find free software to do this, and although it does not hesitate to say ...

    In 4GB, it would mean in Fat32, and there is a risk that your camera does not support them. Are you going to see on the site of the manufacturer if there was a firmware?

    If you want free software then you can use: SD Formatter

    Procedure to Install of SD Formatter

    1. Install the software after finishing the download
    2. Close all running programs on your computer
    3. Run or Execute the installer file
    4. Follow the instructions in the installation window
