Why Initialize a Hard Drive

Why does the Windows system keep asking you or forcing you to initialize your HDD? Here are reasons why HDDs must be initialized and errors that result from uninitialized HDDs:

  • The new HDD does not show up on the PC:

When you plug a brand new HDD into your PC, you may immediately encounter the "The disk does not show up in Disk Management/This PC/Computer" error. In this case, you must initialize it to make it instrumental.

  • Logical Disk Manager cannot access the disk because it is not initialized:

Sometimes, if the hard disk is not initialized as MBR or GPT, you may be warned, "You must initialize the disk before Logical Disk Manager can access it."

  • Error messages such as "Disk 0 is unknown, uninitialized, unallocated" may pop up if you try to turn on a hard drive.

This issue can occur on all Windows systems, such as Windows 10/8/7, and the only way to do it is to fix the "disk not initialized" error.

Hence, based on these reasons, it's necessary to initialize an HDD before we use it. Use the ways above to try. By the way, if you are using an SSD, click the following link to try.

Initialize a Hard Drive FAQs

Windows can't detect or store files on a hard drive that is uninitialized. Hence, it's important to initialize a hard drive into the target partition style. Read the questions and answers below to learn more:

1. What does it mean to initialize a hard drive?

Everything on the hard drive is deleted and erased when it is initialized. The hard drive is now ready for Windows to use. Your drive can be formatted when you initialize it, after which you can put/store files on it. And don't forget to back up your files in advance to avoid data loss.

2. How do I initialize my hard drive in Windows 10?

Follow the steps below to initialize your hard drive:

Step 1. Open Disk Management with administrator privileges: In the search box of your Windows PC, type disk management. Select and hold (or right-click) Disk Management, then select Run as Administrator > Yes.

Step 2. In Disk Management, select and hold (or right-click) the disk you want to initialize, then choose Initialize Disk. If the disk is shown as Offline, first select and hold (or right-click) the disk, then select Online.

Step 3. In the Initialize Disk dialog, after making sure you have selected the correct disk, select OK to accept the default partition style. (Or you can freely choose MBR or GPT.)

3. Should I initialize the disk as MBR or GPT?

It depends on your needs. If your disk is 2 TB or less, select MBR when initializing the drive for the first time. Select GPT if the hard drive is larger than 2 TB. Also, choose a GPT disk as your system disk if you want faster boot times, or choose MBR if your computer is BIOS-based.
