System hacks: Explaining dynamic disks

Microsoft has introduced dynamic disk for many years, but we are basically still used to using the basic disk form, after all, dynamic disk can not install the system. But what are its advantages and disadvantages, we have never experienced it, of course, it is not clear, today I will introduce in detail the usefulness and benefits of dynamic disk, as well as and the basic disk conversion method between each other.

You may encounter a situation where a software must be installed to a specified disk partition, and it so happens that the partition does not have enough available storage space, how would you handle it? Many people may choose two ways: the first is to delete the installed software or saved files in the partition, clean and delete; the second is to use third-party software to adjust the disk partition. Of course, this method of operation requires certain skills, and is not very convenient. In fact, the author’s suggestion is to use “Dynamic Disk” at the beginning of system creation.


What is a “dynamic disk”?

The way disks are used can be divided into two categories: one is the “basic disk”: it is very common and almost all the disks we use are actually basic disks – after all, this is the default system partition setting. Its characteristic is limited by the 26 letters of the alphabet, which means that the disk character can only be one of the 26 letters of the alphabet. Since A and B are already occupied by floppy drives (the “ancient” setting), the only available disk letters are from C to Z. In addition, the basic disk can only have four primary partitions, and the others can only be extended partitions, which means that the system must exist in one of these four partitions, and no more.

Another type of disks is “dynamic disks”: dynamic disks are characterized by the fact that they are not limited by the 26 letters of the alphabet and are named by “volume”. Its biggest advantage is the ability to expand the disk capacity to a non-adjacent disk space and to adjust it freely, and it is this feature that helps us to solve the previously mentioned problems.

So how do you know which type of disk you have? The way is very simple, right-click the Start button of Win10 and click “Disk Management” in the pop-up menu (or press Win+R and type “diskmgmt.msc”).


Note the “Type” of each partition, “Basic” is the basic disk.


Having said their respective advantages and disadvantages, let’s take a look at the relationship between basic and dynamic disks. If the disk in your computer is a basic disk, then you can upgrade to a dynamic disk.

To upgrade to a dynamic disk, select the disk you want to upgrade to a dynamic disk (note that it is not a partition), right-click on it and select “Convert to dynamic disk” in the pop-up menu. Note that when you upgrade from a “basic disk” to a “dynamic disk”, the disk data will not change, but when you return from a “dynamic disk” to a “basic disk”, the disk data will not change. But when you return from “Dynamic Disk” to “Basic Disk”, all data on the disk will be lost.


After upgrading to a dynamic disk, you can start working on the problems we mentioned at the beginning. For example, if we want to expand the space for the D drive, we can install a new hard drive in the computer after booting, set the new hard drive as a dynamic disk in Disk Manager as well, and then go back to the D drive to be expanded right-click to bring up the menu and select “Expand Volume”.



Under the new interface, you can see the newly installed hard drive on the left side, click to select it and then click the “Add” button in the middle.


At this time, all the disk space of the newly installed hard disk to the right, in the “Select Capacity”, fill in the capacity needed for the D disk expansion can be. Note that it is best to fill in the integer, and pay attention to the conversion of 1GB = 1024MB, confirm that there are no errors, click “Next”.


The last thing is to confirm the information screen, we take 20480MB as an example, you can see that the capacity expanded for D drive is 2GB, not the entire capacity of the new drive. After the expansion for the D drive is completed, the remaining space on the new drive can still be expanded for other partitions or a new partition on the newly added drive. Obviously, dynamic disks are much more convenient than basic disks.
