Tip: Sometimes you may find your external hard drive not showing up. What should you do? This post - 10 Situations Where External Hard Drive Not Showing up & Solutions shows you the fixes.

In general, a disk being unknown or uninitialized can be caused by various events including a virus attack, corrupted Master Boot Record, partition loss, bad sectors, and some computer file system corruption. If you are having trouble fixing your hard disk, please try the following solutions.

How to Solve Disk Unknown Not Initialized Windows 10/8/7

Case 1: Disk Unknown, Not initialized, Unallocated

First of all, open Disk Management and find the uninitialized disk. If its disk capacity is shown, that means your Windows operating system has recognized this disk, but its partition is lost or MBR is corrupted due to some reasons. In this case, you can use a professional software to fix the MBR and recover the partition.

Solution 1: Initialize Your Hard Drive

When it comes to hard disk not initialized, the first thing that you may do is to initialize this hard drive. Run Disk Management by right-clicking “My computer” and then selecting “Manage”. You can also press the keys “Win + R” and input “compmgmt.msc” to run the partition management tool.

Next, find the external hard drive connected to THIS computer. You will see this unknown disk appearing as “unallocated”. If this external hard drive does not contain any important files, you can go ahead and initialize the disk without losing data. In Windows 10, initializing the disk to MBR or GPT should directly solve this problem.

Tip: What happens if I initialize my disk? Disk initialization can wipe out all the data and cause data loss. As a result, if you have stored a large amount of data on the external hard drive, an initialization operation like this is not recommended.

Therefore, due to the effects of data loss, this solution is not always the best.

Solution 2: Rebuild MBR

MBR, short for Master Boot Record, is a special type of boot sector at the beginning of the hard drive. It could possibly be corrupted due to many reasons, such as malware infection, accidental power failure, and mistaken operation.

If the MBR gets corrupted, the operating system will no longer know where to access its data. This is when the issue “disk 1 unknown not initialized external hard drive” could occur. Therefore, you need to rebuild MBR for your hard disk to solve this issue.

How to fix MBR in Windows 10?
