D Drive Missing: What to Do if Your D Drive Disappeared?

D Drive Missing: What to Do if Your D Drive Disappeared?

The D drive is an essential component for many computer users, particularly for those who use it to store their personal files, games, and applications. However, the sudden shock of finding that the D drive has mysteriously disappeared from your computer can be quite distressing. Nevertheless, there’s no need to panic. In this article, I will share my personal experience in dealing with a disappeared D drive scenario on a Windows system and how I successfully recovered my data using Disk Drill.


Common Scenarios:

Software Update Glitch

  • Windows Updates can sometimes cause system abnormalities leading to the D drive not showing up.
  • Drive Letters might have been reassigned, causing the D drive to disappear in the process.

Partition Errors

  • Corrupted Drive: The drive partition suffered corruption, making it invisible to the system.
  • Lost Partitions: Due to a system crash or improper computer shutdown, a partition could be lost.

Physical Connection Issues

  • Cable Problems: SATA or power cables connected to the hard drive might be loose or damaged.
  • BIOS Settings: The drive may not be enabled in the BIOS settings, or system setup.

Step-by-Step Guide. D Drive Missing:

Method 1: Check Disk Management

  • Open Disk Management. Right-click on ‘This PC’ or ‘My Computer’, select ‘Manage’, and then choose ‘Disk Management’.
  • Look for the missing D drive. If it’s not visible, you might see an unallocated space where the D drive used to be.
  • If you find the drive without a letter, right-click on it and select ‘Change Drive Letter and Paths’ to assign a letter to it.

Note: Be cautious not to format the drive as this will erase all data.

Conclusion: In some cases, simply reassessing a drive letter can bring the D drive back to visibility.

Method 2: Use Command Prompt

  • Launch Command Prompt as an administrator by searching for ‘cmd’ in the start menu, right-clicking on it, and selecting ‘Run as administrator’.
  • Type ‘diskpart’ and press Enter to access the DiskPart utility.
  • Type ‘list volume’ and press Enter to display all the drives and their respective letters.
  • If the D drive is listed without a letter, use the ‘select volume D’ command to select it, followed by ‘assign letter=D’ to assign the correct letter.

Note: ‘D’ should be replaced with the correct volume number for your drive.

Conclusion: Command Prompt can help troubleshoot and fix issues with the drive’s appearance in Windows.

Method 3: Check BIOS/UEFI

  • Reboot your computer and enter BIOS/UEFI settings by pressing a specific key (often F2, F10, DEL, or ESC).
  • Within the BIOS/UEFI, navigate to the ‘Storage’ or ‘Boot’ settings to see if the D drive is recognized and enabled.
  • If the drive is disabled, enable it using the provided options.
  • Save changes and exit the BIOS/UEFI setup.

Note: Consult your motherboard’s manual for specific instructions on navigating BIOS/UEFI.

Conclusion: Enabling the drive in BIOS/UEFI settings can make it visible again in Windows.

Method 4: Check Physical Connections

  • Shut down your computer and unplug it from the power source.
  • Open the computer case and check SATA and power cables to ensure they are securely connected to the D drive.
  • If cables are loose or damaged, reseat them or replace with new ones.
  • Power up your computer and check if the D drive is now visible.

Note: Handle internal components with care to avoid static damage.

Conclusion: Re-establishing secure physical connections can often restore the D drive’s visibility in the system.

Method 5: Use Disk Drill to Recover Data

  • Download and install Disk Drill from the official website (
  • Launch Disk Drill and select the drive you wish to recover (in this case, the D drive or the equivalent visible in Disk Drill).
  • Click on ‘Recover’ to perform a scan for recoverable data.
  • After the scan, preview the files that can be recovered and choose those you wish to restore.
  • Follow the prompts to complete the recovery process and save the recovered data to a safe location (not the same drive you’re recovering from).

Note: Carefully select items to recover to maximize the chances of successful data restoration.

Conclusion: Disk Drill is a powerful tool that can recover data even when the drive is not showing in Windows.


Precautions and Tips:

Backup Plan

  • Maintain regular backups of critical data to external drives or cloud storage.
  • Use disk imaging software to create an exact copy of your drive for future restoration if needed.
  • Be cautious about software updates and ensure system stability before proceeding.

Extended Solutions

When faced with a disappeared D drive, it’s crucial to explore several avenues beyond the initial troubleshooting steps. For example, using third-party partition manager software can provide more advanced options for diagnosing and repairing disk issues. MiniTool Partition Wizard is a recommended option that greatly complements Disk Management in Windows.

Another approach is to check for hardware malfunctions. Testing the hard drive with diagnostic tools provided by the drive’s manufacturer, such as SeaTools for Seagate or WD Drive Utilities for Western Digital, can help pinpoint if there’s a physical issue with the drive.

It’s also important to consider the impact of system restores or resets. These can unintentionally affect drive partitions, so it’s essential to use these options with caution. Additionally, one should always keep their system protected by reliable antivirus software, like Malwarebytes, to prevent malware-related issues that can cause drive disappearance.


In conclusion, the sudden disappearance of the D drive can be attributed to a variety of causes ranging from simple software glitches to more complex hardware issues. Effective recovery and protection strategies are essential for mitigating the risk of data loss. Employing a combination of built-in Windows utilities, such as Disk Management and Command Prompt, along with third-party tools like Disk Drill, can ensure that your data remains safe and recoverable. Be proactive by maintaining regular backups and staying vigilant with system and software updates to minimize the chances of drive disappearance incidents.
