Issues with initializing a brand new hard drive are easy to overcome by simply formatting it in GPT or MBR partition.

However, what to do if a once-fully-functional disk won’t initialize? Well, hardly anything. But, before surrendering and formatting the drive, there are some things we can try.

If you can’t initialize the disk in Windows 10, try the steps below in order to solve the problem.


What do I do if Disk won’t initialize in Windows 10?

1. Make sure the disk is online

  1. Right-click on the Start button and choose Disk Management.disk management samsung t5 ssd not recognized
  2. Right-click on the uninitialized drive in the bottom left and choose Online from the contextual menu.disk management
  3. Try accessing the drive.

Note: The first thing you need to do is confirm that the disk is online. Flash drives do not need to be set online while configuring, but that’s not the case for standard HDD drives. So, before doing something drastic, enable the drive using the steps above.


2. Run Disk test

If the disk still won’t initialize, consider running a disk test. You can use the system resources, but we prefer downloading and using a third-party diagnostic tool in this scenario. What we need to do is find out the drive is fully functional and without corruption.

Also, along with the software inspection, make sure that your cables are properly connected. In case this is an external drive with the portable case, take it out and reconnect it. After that, give it another try.

Software-wise, try with one of these programs to check for errors. The important thing is not to manually initialize the drive as this requires wiping all data. And if you have anything of value on that drive, wiping it probably not what you want.


3. Try fixing the drive

  1. Open Disk Management (as explained in the first solution).
  2. Right-click on the affected disk and open Properties.
  3. Choose Tools.
  4. Under the Error Checking section, click Check.drive error checking win 10
  5. The procedure might take some time depending on the size of the drive.

Note: If the drive is visible in Disk Management, you can try and repair it with the Error Checking tool. This might or might not work, as the drive might appear as Unknown.


4. Initialize the drive

  1. Open Disk Management.
  2. In the bottom left, click on the uninitialized disk and choose Initialize Disk from the contextual menu.cannot initialize disk
  3. Choose the partition style, GPT or MBR. This will wipe everything from the disk storage.cannot initalize disk
  4. Click Ok and try accessing the drive.

Note: Finally, if you’re unable to initialize the drive, the only thing you can do is format the drive and start from scratch.

Of course, before doing this, try some of the free or paid recovery software to get your data out of it. You can try one of these programs to do so but have in mind that you’ll hardly manage to get the 100% of the data.


The above solutions should help you whenever you can’t initialize the hard drive.

If you’re still unable to initialize the disk, consider replacing it. The most likely reason for this is the hardware malfunction and it’s hard to fix it.
