Step 2: Click Device Manager and expand "Disk drives".

Step 3: Locate and check the state of the second hard drive.

If your disk driver is covered by a yellow exclamation mark, you will need to update the disk driver. This is typically done through the Device Manager.

Step 3: Right-click the second hard drive that is not detectable and select "Update driver".

Step 4: Click "Automatically search for driver software online" and wait for the process to complete.

When the process finishes, restart your PC and check the disk again in the Device Manager. It will display as a normal disk by then and you can proceed to Phase 3 to continue fixing this issue.

If Windows can't find a new driver for your hard drive, you can try downloading one from the device manufacturer's website and follow their instructions to complete the driver update process.

Phase 3. Scan and Restore Saved Data from the Second Hard Drive

To protect data on a problematic hard drive not recognized by Windows, use an external drive or a bootable USB drive to access the hard drive, then copy the data to a safe location. If the hard drive is not recognized, try booting from a Linux live CD or USB drive, which may be able to access the hard drive and retrieve the data. If the hard drive is still not accessible, consider using a data recovery software, such as Qiling or Recuva, to scan the drive and recover any recoverable data.

If your second hard drive is a new device, you can skip this phase and move to Phase 4 to make it detectable again.

However, if you saved important data on the second hard drive, it's highly recommended to extract the saved data beforehand. You can use professional hard drive recovery software like Deep Data Recovery to scan the second hard drive and find all saved data.

Additionally, it may be necessary to reinstall any software or drivers that were affected by the restore process.

Step 1. Launch Deep Data Recovery in Windows 11/10/8/7, choose the file type, and click "Next" to proceed.

Step 2. Choose the place where you lost data. Then, click "Scan".

Step 3. After scanning, use the file format filter to locate the files you need, and then click the "Preview" button or double-click a file to view its content.

Step 4. To recover a lost file, select the file by clicking the checkbox next to it, then click the "Recover" button to restore the file to a secure location.

To resolve the issue of a hard drive not being detected, save the data to another secure device, preferably an external hard drive. Then, you can remove the problematic hard drive and replace it with a new one, making the hard drive detectable and working again.

Phase 4. Check the State of Second Hard Drive in Disk Management and Make It Detectable

To fix Windows 10 not detecting a second hard drive due to logical errors, you can try running the built-in Check Disk (chkdsk) utility on the problematic drive. This can help identify and repair any errors that may be preventing the drive from being recognized.

If your disk shows up properly in BIOS and Device Manager, but Windows can't detect or recognize it properly, it's likely due to one of four common errors.

• RAW error
• Device not initialized or shows unallocated 
• The second hard drive shows No Media

To resolve the issue of the second hard drive not showing up, open Windows Disk Management and check its display state. If it's not visible, follow the necessary fixes to make it appear.

# 1. Hard Drive Shows RAW - Format RAW Drive to NTFS

If the hard drive shows as Online, but the partition displays as RAW, you can format the partition to NTFS.

Step 1: Right-click on This PC/My Computer, select "Manage".

Step 2:To fix a not recognizing hard drive in Disk Management, locate the RAW partition of the drive, right-click it, and choose the "Format" option. This will allow you to format the partition and potentially resolve the issue.

Step 3: Select NTFS as the file system for the partition and confirm with "OK".

# 2. Hard Drive Shows Not Initialized + Unallocated

If the hard drive shows as a not initialized or unknown drive, don't worry, it's likely just a minor issue that can be resolved with a few simple steps.

You can directly apply Windows partition manager software - Qiling Partition Master with its Initialize to MBR or Initialize to GPT feature to make the hard drive show up now.

Step 1: Launch Qiling Partition Master on your PC.

Step 2:Right-click the target hard drive and select the appropriate initialization option, either "Initialize to MBR" for Master Boot Record or "Initialize to GPT" for GUID Partition Table, depending on the desired partition scheme.

Step 1. Open Qiling Partition Master and connect the hard drive or SSD to your PC.

Right-To initialize your target HDD or SSD, select it and choose the appropriate option based on its type: for MBR, select "Initialize to MBR", and for GPT, select "Initialize to GPT".

Step 2.A new feature to initialize a disk to either MBR or GPT will be added, allowing users to execute the operation and apply the changes.

0:00-0:22 Initialize to MBR; 0:23-0:49 Initialize to GPT;

The process of creating multiple partitions on a second hard drive involves repeating steps 4 to 6, where you create a new partition, format it, and assign a drive letter, until you have created the desired number of partitions.

After following the process, you can now utilize the second hard drive in Windows 10 to save data again.

# 3. Hard Drive Displays as NO Media - Update Driver, Take It to Device Repair Center

If the second hard drive shows as "No Media" in Disk Management, you'll have two choices:

• 1st. Go back to Phrase 2 and update the device driver.
• 2nd. Take the hard drive out of your computer, and send it to a local device repair center for repair.
