Step 1: Search for Disk Management using Windows Search Bar

Firstly, Open the Windows Search bar and Search for Disk Management and click on create and format Hard disk Partitions.

I am showing in Windows 10, for other Windows versions. Maybe it will be a little bit different but you have to go to the Disk Management okay.

Step 2: Look at the Hard Disk Space

After clicking on Disk Management, you will see the Hard drive section.

As you can see, there is only C Drive available for me with 930GB of space. I am going to partition the C drive to create a new drive.

Step 3: Right-Click on the Drive and click on Shrink Volume

Now Right-click on the C drive and click on the Shrink volume option.

Step 4: Select the Size of the New Disk and Click on Shrink

Here, you need to understand this carefully.

I want a new drive of approximately 300GB and we need to enter the amount of space needed for a new drive we’re creating from the C drive.

For Example, I have 930GB in my C drive, and when I create a new drive of 300GB. Then, the C drive will have 930GB-300GB=630GB. Because we’re partitioning from C drive, right.

So, Let’s Understand what we’ve on the screen right now.

  • Total size before shrinking in MB: 952728

952728MB is equal to 931GB. The amount of space we’ve in C drive before creating a partition.

  • Size of Available Shrink Space in MB: 859295

859295MB is equal to 830GB (Approx). This is the highest amount of space we can use to create a new drive.

In simple words, We can’t create a new drive of more the 830GB, okay.

  • Enter the Amount of Space to Shrink in MB: 319294

319294MB is equal to 311GB. In this section, You have to add the amount of space you need for a new drive.

I want a drive of 300GB and I entered here 319294MB. You also have to enter the amount of space you need for a new drive in MB, not in GB.

If you’re confused with numbers and thinking about how to enter the exact same amount of space in MB so that I can get the exact space for a drive in GB.

Here, I have a trick. You need to enter the 6 numbers in MB and you will get the amount of space in 100GB, 200GB, 300GB, or more.

See, you need to enter 6 numbers and the first 3 numbers play an important role.

For Example, I have entered 319294 in MB and the first 3 numbers are 319.

So, 319294MB is equal to 311GB. I want 300GB for a new drive but I got 311GB of space for my new drive. The first 3 numbers are 319 and I got 311GB. 319 and 311 these are nearly the same.

Also, you can calculate like 3 Lakh (300000) MB is equal to 3GB Approx.

As you can see, this calculation is inaccurate. I want 300GB but I got 311GB but a little bit difference in size doesn’t matter for me.

If you want to calculate the total exact amount of space, then I am sure you can find an MB to GB converter online tool on Google.

  • Total Size after shrinking in MB: 693433

693433MB is equal to 630GB (Approx). This is the amount of space left in C drive after creating a new drive from it.

Now, Enter the amount of space you need (In MB) and click on Shrink.

Step 5: Unallocated Drive
