How to Format the Hard Drive of Your Windows 10 PC

 

Formatting is a computer process wherein all data is being wiped out from a hard drive so that new data can be written on it. There are a few different file systems you can format a drive to (NTFS, FAT32 and exFAT being the most popular), each of which works fine in Windows but may not work across different devices.

If your computer is experiencing sluggishness, you may notice or hear that its hard drive is struggling with reading and writing (grinding clicking sounds on your PC). This is a solid indicator that your computer needs a reformat.

NOTE: It is not possible to format the C: partition in Windows, since this is where the OS system files are residing. You can only format the secondary (or external) hard disk or another partition in the primary hard drive.

Formatting a Hard Drive in Windows 10

STEP 1: Press the Windows key, then type “disk management” and then select Create and format hard disk partitions.

Here you’ll see all the hard drives – internal and external – connected to your PC. If you’ve just inserted a new hard drive, it should be listed, but the space within it will be “Unallocated.” If you want to format an existing active hard drive, you can do one of the following:

  • Right-click the drive you want to format, then select Delete volume, which will turn that drive (or partition) into unallocated space and delete all the data on that drive. This is useful if you want to create partitions (more on that in a bit).
  • Alternatively, right-click the drive you want to format, then select Format, which will take you to the options for formatting your drive directly into a different file system.

STEP 2: If you went for the Delete volume option and that drive is now “Unallocated space,” you’ll need to decide whether you want the whole drive to be one partition or if you want to create separate partitions on that drive.

NOTE: This can be useful for lots of things, such as if you want to install a second operating system, such as Ubuntu, on that drive, or if it’s an external drive, you might want to have an NTFS partition for your Windows stuff, but a dedicated exFAT partition also, which is compatible with your PS4.)

STEP 3: Once you’ve decided, right-click the big black bar representing the Unallocated space, then click New Simple Volume.

NOTE: In the example below, we’re going to create a 60GB NTFS partition first, so that’s “60000” in MB. If you want the whole drive to be one partition, just type the same number as the “Maximum size” displayed. 

STEP 4: Click Next to continue.

STEP 5: Next, choose what drive letter you’d like your new drive/partition to have.

STEP 6: On the next screen, here are the important things you need to take note of:

  • File system: Choose from NTFS, exFAT or FAT32. NTFS is the fastest system for Windows, but the least compatible with other devices. FAT32 is pretty universal but limits file sizes, while exFAT is a modernized version of FAT32 without the size limits, so generally a better option.
  • Allocation unit size: The bigger the unit size, the faster the read speed technically, but you should adapt this to the size of the files on your drive, otherwise you risk wasting space. If you’re creating a hard drive for watching movies, go for a big allocation unit size. If it’s more general stuff, go for a smaller one.
  • Perform a quick format: If you have time to spare, we recommend not selecting this option. A full format will scan your disk for bad sectors and fix them, which will ensure better performance in the long run.

STEP 7: Once you’ve selected the options that suit you, go ahead and click Next, then click Finish.

The drive or partition will be created, and you’ll see it in your Disk Management window. Notice that the other half of our drive is still Unallocated. If we want to fill this up, we just repeat the process above but with the parameters we want for that partition.
