Opened File Explorer and noticed that your D drive is missing? Even though it was full of files, Windows is treating it as though it never existed. Most of the time the data itself is fine, and the cause is something trivial like a missing drive letter. Nonetheless, you need to take the right approach in case it\u2019s not<\/em> something trivial. We\u2019ll guide you through diagnosing the issue, recovering the data, and getting the drive back to working order. Missing data is our specialty, and these methods are the same used by our recovery experts who\u2019ve seen this problem more times than they can count.<\/p>\r\n

<\/span>Why Is My D Drive Missing? Start in Disk Management<\/span><\/h2>\r\n

Disk Management is preferred over File Explorer when checking a D drive that\u2019s suddenly missing, as it lists all physically connected drives, including those with no drive letter, marked as Offline, or showing as RAW or Unallocated. You first need to check how the drive is being read by Disk Management. Here\u2019s how:<\/p>\r\n

    \r\n\t
  1. Right-click Start<\/b> and click Disk Management<\/b>.<\/li>\r\n\t
  2. Find your disk in Disk Management based on its capacity.\"Finding<\/li>\r\n\t
  3. Click Action<\/b>, then Rescan Disks<\/b> to have Disk Management scan for the drive one more time before we proceed.<\/li>\r\n<\/ol>\r\n

    Here\u2019s what each reading means, and what you should do next:<\/p>\r\n

    If the drive isn\u2019t appearing in Disk Management at all, check out how to recover data from a hard drive that\u2019s not detected<\/a>. It goes into this specific scenario in more detail, even if the drive appears dead<\/a>.<\/div>\r\n

    <\/span>How to Recover Files From the Missing D Drive<\/span><\/h2>\r\n

    A missing D drive is a file problem as much as a drive problem, because everything you kept on the partition is out of reach for as long as Windows cannot mount it. Because several fixes further down this page also write to the disk, it\u2019s extremely important that you get the files off first<\/b>, then fix the drive second, or you otherwise risk the data being lost for good.<\/p>\r\n

    Of course, with any tool, the data recovery software<\/a> you choose heavily depends on the quality of the results. That\u2019s why we go with Disk Drill, because even with its advanced recovery capabilities and features, it\u2019s usable even for beginners who don\u2019t want to follow an overly technical recovery process. As long as the drive is visible in Disk Management and reading the correct size, it can be scanned.<\/p>\r\n

    Follow these steps to recover data from a D drive that\u2019s not showing up:<\/p>\r\n

      \r\n\t
    1. Download Disk Drill<\/a> from the official site. Install it to your machine, and open it.<\/li>\r\n\t
    2. Select your D drive from the list of connected storage devices, then click Search for lost data<\/b>.\"Selecting<\/li>\r\n\t
    3. Choose Universal Scan<\/b> if prompted to choose a scan type, as Advanced Camera Recovery<\/b> is best for recovering fragmented videos shot by cameras and drones.\"Choosing<\/li>\r\n\t
    4. Click Review found items<\/b> when the scan is complete. Alternatively, if you simply want to recover everything, click Recover all<\/b> now.\"Reviewing<\/li>\r\n\t
    5. Preview and select the D drive data that is missing and you want to recover. Your data will be organized by its state. Files under Existing<\/b> are files that aren\u2019t deleted but inaccessible, whereas Deleted or lost<\/b> and Reconstructed<\/b> holds data that has been deleted or recovered by file carving, respectively. Click Recover<\/b> when ready.\"Selecting<\/li>\r\n\t
    6. Choose a separate physical drive to store the data, then click Next<\/b> to complete recovery. Disk Drill lets you recover 100 MB for free; enough to recover critical files and make sure the software works.\"Choosing<\/li>\r\n<\/ol>\r\n

      <\/span>How to Fix a Missing D Drive<\/span><\/h2>\r\n

      Once you\u2019ve recovered all the data you needed to, it\u2019s safe to move on to fixes. Refer to the table at the beginning of the article for targeted solutions based on your situation, or follow through each method if you\u2019re not sure.<\/p>\r\n

      <\/span>Method 1:<\/span> Assign the D Drive Letter in Disk Management<\/span><\/span><\/h3>\r\n

      Start here if the partition is sitting in Disk Management saying Healthy at the correct size, with no letter beside it. It is the easiest case there is, and a common one. Windows only mounts a volume into File Explorer once that volume has a drive letter, so a partition without one is invisible to everything you normally use while staying completely intact.<\/p>\r\n

      These steps will show you how to reassign a drive letter to a D drive that\u2019s missing it:<\/p>\r\n

        \r\n\t
      1. Right-click Start<\/b> and click Disk Management<\/b>.<\/li>\r\n\t
      2. Right-click the partition with no drive letter, then click Change Drive Letter and Paths<\/b>.\"Opening<\/li>\r\n\t
      3. Click Add<\/b>.\"Adding<\/li>\r\n\t
      4. Select the D drive letter from the dropdown, then click OK<\/b>.\"Assigning<\/li>\r\n<\/ol>\r\n

        <\/span>Method 2:<\/span> Change the Drive Letter Back to D:<\/span><\/span><\/h3>\r\n

        This method closely follows the one before, but is for times when the drive is appearing, just with the wrong drive letter (like E:, F:, etc). This can happen if the drive is reconnected, a new drive is added, or when Windows reassigns drive letters.<\/p>\r\n

        This is another simple fix, but if you already have another drive with the D: letter assigned, you\u2019ll need to assign a different letter to that drive before you can use D: again.<\/div>\r\n

        This is how you restore a missing D: drive letter after it has been reassigned:<\/p>\r\n

          \r\n\t
        1. Right-click Start<\/b> and click Disk Management<\/b>.<\/li>\r\n\t
        2. Right-click the partition with the incorrect drive letter, then click Change Drive Letter and Paths<\/b>.<\/li>\r\n\t
        3. Select the currently assigned drive letter, then click Change<\/b>.\"Changing<\/li>\r\n\t
        4. Choose D: from the dropdown, then click OK<\/b>.\"Choosing<\/li>\r\n\t
        5. Click Yes<\/b> when asked to confirm.\"Confirming<\/li>\r\n<\/ol>\r\n

          <\/span>Method 3:<\/span> Bring the Disk Online<\/span><\/span><\/h3>\r\n

          Sometimes it\u2019s not a problem with the partition, but the disk itself. If you see the drive in Disk Management and it\u2019s showing as \u201cOffline\u201d, then Windows detects it, but is not reading it as available. Bringing it back online leaves the partition and data intact, allowing you to continue as if nothing happened.<\/p>\r\n

          This is how you bring a D: drive that disappeared back online:<\/p>\r\n

            \r\n\t
          1. Right-click Start<\/b> and click Disk Management<\/b>.<\/li>\r\n\t
          2. Right-click the grey box of the disk on the left, then click Online<\/b>.\"Bringing<\/li>\r\n<\/ol>\r\n

            After a few seconds, the drive should now show as \u201cOnline\u201d, and the partition (and its data) will be accessible through File Explorer.<\/p>\r\n

            If you are asked to initialize the disk at any point, cancel the process and recover the data if you haven\u2019t already. Initializing the disk writes a fresh, empty partition table over the old one which affects data recovery.<\/div>\r\n

            <\/span>Method 4:<\/span> Recover the Missing D Partition<\/span><\/span><\/h3>\r\n

            Is the drive showing as \u201cUnallocated\u201d, or the partition as \u201cRAW\u201d? It could be the case that the partition record itself is damaged rather than truly gone. In that case, it\u2019s sometimes possible to recover the damaged partition<\/a> and get the drive back exactly as it was, files and folder structure included, without creating a new one. This is where TestDisk comes in handy, a partition recovery tool that restores the partition by fixing the underlying problems.<\/p>\r\n

            As we cover in our TestDisk review<\/a>, TestDisk is not particularly beginner-friendly. It uses a command-line interface (CLI), employs technical language, and one mistake can lead to a change that causes irreversible loss. For that reason, don\u2019t skip our recovery steps<\/a> if the files matter.<\/div>\r\n

            Here\u2019s how you restore a D: drive that\u2019s missing with TestDisk:<\/p>\r\n

              \r\n\t
            1. Download<\/a> and extract the contents of TestDisk. Open testdisk_win.exe<\/b>.<\/li>\r\n\t
            2. Press Enter<\/kbd> to create a log file.\"Creating<\/li>\r\n\t
            3. Use the up and down directional arrows to highlight the drive, then press Enter<\/kbd>.\"Selecting<\/li>\r\n\t
            4. Choose your partition table type, then press Enter<\/kbd>.\"Choosing<\/li>\r\n\t
            5. Press Enter<\/kbd> on the Analyse<\/b> option.\"Selecting<\/li>\r\n\t
            6. Press Enter<\/kbd> to begin the quick search.\"Starting<\/li>\r\n\t
            7. Press Enter<\/kbd> on the screen that shows unrecoverable partitions.\"The<\/li>\r\n\t
            8. Highlight the missing partition, then press Enter<\/kbd>. You may need to change the partition characteristic to P using the left and right arrow keys, or perform a deeper search.\"Selecting<\/li>\r\n\t
            9. Hover over the Write<\/b> option, then press Enter<\/kbd>. If your partition wasn\u2019t found, try a Deeper Search<\/b> instead.\"Writing<\/li>\r\n\t
            10. Press Y<\/kbd> to confirm.<\/li>\r\n<\/ol>\r\n

              <\/span>Method 5:<\/span> Recreate and Format the D Drive<\/span><\/span><\/h3>\r\n

              Formatting is the final option for restoring a D drive that hasn\u2019t been restorable with the previous methods. This is a last-resort fix<\/b> that basically clears out the drive and resets everything on it.<\/p>\r\n

              The exact steps you take slightly differ depending on the disk\u2019s state:<\/p>\r\n
