    Cannot see my data storage HDD (confession enclosed)


    I have had 2 HDDs.


    1 x Cdrive HDD
    1 x Ddrive data-storage 700GB HDD

    Cannot see drive D. No letter assigned. Disk Management only offers option to delete volume.

    Confession > first attempt to see what Linux is all about has resulted in me indvertantly installing an 8GB linux partition inside the 700GB storage drive.

    I need my pics, mp3s & mp4s pdfs etc etc back on line

    Can you please post a screenshot from DISKMGMT.MSC, expanded to full-screen and with the columns spread so that we can see all of the text in the cells in the upper portion.

    Also, you may or may not have destroyed the previous presumably single-partition 700GB drive, by creating that 8GB partition somewhere on it (or replacing whatever was there before). So you may have two partitions now, or just one 8GB partition, or who knows until we see the screenshot.

    Finally, do you have a backup of what was on your D-drive previously? Or not?

    I think your data is ok, but I won't be certain until I see the PW screen shot I previously requested. The Disk Management image is great, but PW tells me a little more and that utility might come in handy. All I need to see is the main PW window, grab the screen shot and close PW for now.

    I'd also like to know more about how you did all of this. It's only to get as much information about the issue before proceeding.

    When you tried to install Linux did you make the 8GB part or did the install process?

    If you made the 8GB how did you slice out the 8GB (which tool? Diskpart, Disk Management, Partition Wizard, other?)

    Can you point me to the instructions you followed for the Linux install?

    Part of the problem is the Active flag is set on Disk 1.
    The correct part is Disk 0 - so that is ok

    Launch an elevated Command Prompt (right click, select Run as administrator)
    type the following commands
    Diskpart
    lis dis
    sel dis 1
    lis par
    exit

    Post a screen shot of the Command Prompt window.

    Thanks

    I recall nothing about the linux sitting there in the back corner. I have a 120GB SSD I've been plugging in to try out linux so I would not do any damage as I'm 'all thumbs'. Looks like i neglected to unplug the 2nd HDD.

    Here's the command prompt -

    If your 700GB partition on the second drive used to be NTFS, it no longer is. It's now EXT4 and 690GB (reduced to make room for your 8GB Linux partition), which is not recognized by Windows. That's why it looks like it does through DISKMGMT.MSC. Obviously that came from the Linux install story.

    It shows 15.4GB in use on that partition, with 675GB free. If you're lucky, it might be completely undamaged... just in an EXT4 partition. So your data files might still be accessible, just not from Windows right now.

    Anyway, although I haven't done it maybe others who know can confirm or deny that Partition Wizard can possibly convert the current EXT4 partition back to NTFS. I know PW can convert partitions from FAT32 to NTFS and vice versa, but I don't know if it can convert EXT4 to NTFS directly. If so, that's the simplest way to get it back.

    If PW can't convert EXT4 to NTFS directly, then since you're only using 15GB another recovery method might be to use use Linux to copy the contents of the EXT4 partition to a FAT32 partition. You can use PW to make room for that FAT32 partition by shrinking that large EXT4 partition by 17GB or so, and allocate a FAT32 partition of 17GB in the now available space just freed up by reducing the size of the EXT4 partition.

    Then in Linux copy the file contents of the EXT4 partition to the temporary FAT32 partition. Then boot to Windows, and using Partition Wizard delete the EXT4 partition, convert the FAT32 partition to NTFS, and then enlarge the now NTFS 17GB partition to use all of the space just freed up when you deleted the EXT4 partition.

    You now have your NTFS partition back to its 690GB size (we haven't touched the 8GB Linux partition). It's the current EXT4 partition now converted back to NTFS through a series of operations described above. And presumably the 15GB of data files is still present and undamaged.

    If this 15GB is critical and irreplaceable, I'd strongly recommend you back up that data somewhere (in Linux, if that's the only way to get to it right now) before fooling around with partitions and running the risk of doing something wrong and losing that data. You don't want to lose that data, of course.

    Linux couldn't "mount" the drive, nor look inside.

    Minitool doesn't seem to like it either. Looks like a format coming up. I'll wait a day in case someone offers solution.

    My mistake, when I was writing the post, I edited it to correct an error.
    Unfortunately, I also removed the critical piece of information, the actual program name.

    I corrected post# 5, but I don't think it's necessary to run it now that you posted the Partition Wizard (PW) screen.
    dsperber identified the problem, now let's see if there's a way to undo what the Linux install did.

    Let's take a look at what's on the disk using Mint Mate on a thumb drive


    1. Download the Rufus bootable USB drive creation utility
    Rufus home page
    Rufus FAQ
    2. Download the Linux Mint Mate ISO
    Select a download mirror from the pages below that is nearest your location to lessen download time
    Linux Mint Mate 32 bit (32 or 64 bit machines)
    Linux Mint Mate 64 bit (only 64 bit machines)
    Linux Mint Mate documentation [PDF]
    3. Create a bootable USB thumb drive using Rufus and the Linux Mint Mate ISO
    Mint Mate is 1.3 GB, so you need a thumb drive with at least 2 GB.
    Creating a bootable thumb drive erases all data on the thumb drive.
    If you have data on the thumb drive that you need, move it to your Hard Drive or burn it to an Optical Disc.
    1. Connect the USB thumb drive to a USB port
    2. Launch Rufus

    3. The fields in Rufus are filled in with defaults. The defaults work well, but a few things need to be verified or changed.
      1. Verify that Rufus selected the thumb drive you want to write. Change the Device if the wrong USB thumb drive is presented in that field.
      2. Change Create a bootable disk using from the default to ISO image
      3. Select Linux Mint Mate ISO as the source. The file should appear on the status bar
      4. unTick Create extended label and icon files
      5. Compare your Rufus window with the image above. If everything other than the Device field are the same, then continue to the next step. Note that the ISO name in the status bar is subject to change as new versions are released
      6. Press the Start button
    4. The status bar notifies you when the process is Done
    5. Press the Close button


    Leave the Linux Mint Mate thumb drive connected for the next steps
    4. Boot to Linux Mint Mate
    Save any files you are working on, then Restart your machine
    Check your machine documentation to determine the key that brings up the Boot Order startup menu. This example is from an HP laptop that assigns it to the F9 key.
    When the machine begins to start again (black screen) tap the F9 key to bring up the Boot Order startup menu. There is only a short time to "catch" the Boot Order menu. If Windows starts, you will have to try again.

    There might be an option screen presented when Mint Mate starts, you can either wait for the default timeout or press enter.
    5. Press Computer to display the disk drives
    The names will be unfamiliar, and you'll have to identify them by size. Open the 690 GB drive and post a screen shot.

    Look in the Mint Mate menu for a snapshot application, there are two of them.
    If you're not already connected to the Internet, connect now and post the screen shot.
    This can all be done in Mint Mate.



    If you see your files, that's great. The easiest thing to do would be to create a folder on your c: drive and copy your files to that new folder.

    If you see Linux Operating System files - a different tact will have to be taken.
