finding a not listed hidden hdd on hppvillion running windows 10 its a western idgigial drive thats lighting up and plugged in securely

If you're trying to find a hidden hard drive on an HP Pavilion running Windows 10, here are some steps you can take to troubleshoot and ideally resolve the issue: ### 1. Check Connections - Ensure that the hard drive is securely connected to the USB port or wherever it's plugged in. - Try connecting it to a different USB port or a different computer to see if it's recognized. ### 2. Check Disk Management 1. Press `Windows + X` and select **Disk Management**. 2. Look for the connected hard drive in the list. It may be unallocated or not assigned a drive letter. 3. If it appears but does not have a drive letter: - Right-click on the drive and select **Change Drive Letter and Paths**. - Click **Add**, then assign a new drive letter to the hard drive. 4. If it shows as unallocated: - Right-click on it and select **New Simple Volume** to create a new partition (be cautious, as this will delete all data on the disk). ### 3. Check Device Manager 1. Press `Windows + X` and select **Device Manager**. 2. Expand the **Disk drives** section and see if your hard drive is listed. 3. If it's there but has a yellow exclamation mark, right-click on it and select **Update driver**. 4. If it’s not listed, try scanning for hardware changes by clicking `Action > Scan for hardware changes`. ### 4. Run Hardware and Devices Troubleshooter 1. Open Settings by pressing `Windows + I`. 2. Go to **Update & Security** > **Troubleshoot** > **Additional troubleshooters**. 3. Select **Hardware and Devices** and run the troubleshooter. ### 5. Check for Power Management Settings Sometimes USB devices are turned off to save power: 1. Open **Device Manager**. 2. Expand the **Universal Serial Bus controllers** section. 3. Right-click each USB Root Hub, and choose **Properties**. 4. Go to the **Power Management** tab, and uncheck the box that says "Allow the computer to turn off this device to save power." ### 6. Use Commands in Command Prompt 1. Press `Windows + X` and select **Windows Terminal (Admin)** or **Command Prompt (Admin)**. 2. Type `diskpart` and press `Enter`. 3. Then type `list disk` and press `Enter`. This will show all disks connected to the system. 4. If your drive is listed, you can use additional commands to select it and explore further. ### 7. Update Windows Make sure your installation of Windows 10 is up to date, as updates can fix bugs and improve hardware compatibility: 1. Go to **Settings > Update & Security > Windows Update**, and check for updates. ### 8. Check for File System Issues If the drive is still not detected: 1. Open **Command Prompt** as Administrator. 2. Type `chkdsk E: /f` (replace E: with the letter of your drive if it's within Disk Management) to check for errors. ### Conclusion If none of these steps work, the hard drive may be faulty. Consider testing it on another system, or using data recovery software if necessary. If under warranty, it may be best to reach out to Western Digital support or the place of purchase for further assistance.
