Several factors can lead to the emergence of the disk unreadable issue. Hence, it's essential to analyze the root cause first. Most disk errors are caused by bad sectors, malware infections, corrupted file systems, or damaged Master Boot Records.

Fixing this Unknown Disk error may involve various stages, ranging from easy to challenging. To gauge the difficulty level of fixing it, start by opening Disk Management and locating the uninitialized disk. If the disk volume is still readable, it implies an easier solution.

But what if the disk volume isn't readable? Fixing it becomes much more challenging as you may need to disconnect the disk from the SATA cable and power (if it's an internal HDD). Then, reconnect the connections to check for any errors in the motherboard connection.

First, open Disk Management where you checked the disk condition earlier. Alternatively, you can open it by pressing Windows + R, then typing compmgmt.msc and selecting Disk Management. Locate the unallocated disk, right-click on it, and initialize it as MBR or GPT.

However, note that this method will erase all data on the HDD. Therefore, ensure there's no important data on the disk before initiating the initialize process.

Rebuild MBR Partition

MBR, or Master Boot Record, is a special partition that manages various aspects of the disk. MBR can get corrupted due to malware infections, unstable power supply, or incorrect operations.

If you find the MBR partition is damaged, you can repair it using third-party applications like MiniTool Partition Wizard. This application is widely used among users and is responsible for managing partitions on computers.

Simply run the application, select the unreadable disk, and click on Rebuild MBR. Once the process is complete, the disk will be readable, and you can access the data within it.

Backup Data to Another Disk

Sometimes, when an HDD reaches the end of its lifespan, it's better to take preemptive action by transferring its data elsewhere. You can use third-party applications like EaseUs Data Recovery Wizard for this purpose.

Just open the application, scan the files on the disk, and recover the data from the disk to another location. Then, proceed with the first point above by initializing the unallocated disk.

Update HDD Drivers

Locate the unreadable disk and right-click on it, then select Update Driver. Choose "search automatically" and let the device search for the latest available drivers for the disk. Once the process is complete, reboot your PC.
