Generally speaking, a new hard disk needs to go through the process of low formatting, partitioning, and advanced formatting, so that it can be used to store information.

But before the new hard disks we purchased leave the factory, the hard disk vendor has done a low-level formatting operation on the hard disk just with one click. So, we need to partition and format the system hard disk before using it.

Nowadays, however, many people are worrying about the problem that how to partition the system hard disk. Because they have little knowledge of computer operation. In fact, there are two situations for partitioning the system hard disk. One is to partition the system hard disk before installing the system, and the other is to partition the hard disk after installing the system.

1. How to Partition the System Hard Disk?

There are many users purchasing brand computers or laptops. Once bringing them home, they just need to release the system with a simple action. After the system is released, they must find that there is only one C drive in their computers, so they want to separate several more drives that they can have enough capacity.

Therefore, how to partition the system hard disk is a difficult problem for them. But they don’t need to worry about it anymore, because this article will show you the solution.

1. Right-click the button This PC on the desktop to open the Property

2. Turn on the System Protection. Because sometimes the system to protect C disk data may cause partition failure, so we have to shut it down first

3. Click the Configuration, choose the Disable System Protection

4. Make sure to close the System Protection

5. Back to the desktop, right-click the button This PC, select Management

6. Click Store

7. Click the Disk Management to open the system hard disk manager

9. Enter the amount of compression. For example, if we first enter 102,400MB, it equals to 100GB

10. At this time, right-click the C drive that is not partitioned and select Compressed Volume

11. The space after compression is unallocated, right click and select New Simple Volume

If you follow the steps above one by one, you may partition the system hard disk well.

2. Common Problem

One of the most common problems at the beginning of partitioning is that the capacity is not allocated properly. The capacity of C drive originally has more than 20G, but it only has less than 10G left after daily use. Even if everything is installed on the D drive, the remaining space of C drive is still getting smaller and smaller.

3. How to Transfer the Capacity Of D Drive to C Drive?

So, how should we solve this problem? Let’s take a look at the following method. This method is only suitable for moving all the space of the D drive to the C drive. If you want to transfer only a part of it, it can be solved by following the system prompt or searching on the Internet. There will be more steps.

  • First, we need to back up the D drive. For example ,we can copy the contents of the D drive to the mobile hard drive. Here, I must emphasize once more that you have to back up the D drive
  • Because the hard disk itself is not big, I simply gave it to the C drive this time.
  • After the D drive is backed up, right-click This PC
  • Click Manage
  • Click Computer Management
  • Select Disk Management on the left, thus you can see the disks on the computer and their respective spaces.
  • Because we have backed up the contents of the D drive, we will delete the D drive next.
  • Right-click the D drive and select the Delete. Then you will see that D drive is gone.
  • Finally, the unallocated space is left there.
  • Since the remaining space is unallocated, we can’t see the unallocated space when we turn on This PC, what we can see is only that the D drive is no longer exist.
  • Next, go back to the disk management interface, right-click the C drive, and select the Expand C drive. The default expanded space is all unallocated space. If you need to allocate all the space to the C drive, just click the button OK.
  • After completing this step, we should open This PC again, where you can see that the C drive has obtained the space of the D drive.
  • Then, according to personal needs, you can move the contents of the previous D drive to the C drive.

Due to the previous installation path on D drive no longer exists, if the software was installed on the D drive before, it might cause some information in the registry to have the link under path invalid, which requires us to manually modify or reinstall it in subsequent use.

4. Conclusion

The methods mentioned above are simple ways to partition the system hard disk and to allocate the space of D drive to the C drive. In theses ways, you can easily allocate the system capacity properly. But before you do this, you must remember to back up the D drive. If you have any questions about the partition or capacity of the system hard disk, you can see this article.
