How To Convert A Dynamic Disk Into A Basic Disk

For those of you unfamiliar with the concept, the basic disk is used for primary logic drives and partitions, and serves as the storage disk type most often used with the Windows operating system.

The basic disk provides a simple storage solution, and allows for the creation and deletion of primary and extended partitions, the creation and deletion of logical drives within an extended partition, and the ability to format a partition and mark it as active.

Table of Contents

A dynamic disk will provide features that are not possible on a basic disk. They allow the partitioning of various volume types such as spanned, striped, mirrored, and RAID-5. These disks tend to offer greater flexibility for volume management. Since the release of Windows 10, dynamic disks have been deprecated and are generally no longer recommended for use.

One of the primary reasons that a dynamic disk is no longer considered useful is the introduction of newer Storage Spaces technology that can help protect your data from drive failures. A long-standing problem with dynamic disks is the inevitability they become faulty, causing drive failures and the need to revert back to basic disk.

How To Convert a Dynamic Disk Into a Basic Disk

A great thing about both disks is that they’re interconvertible, meaning you can convert one into the other and vice-versa. The ways in which this is possible is two-fold; through the Disk Management tool or Command Prompt. 

The process will require some computer competency but is relatively easy even for a novice. We’ll attempt to simplify both conversion methods and aid you in how you can convert a dynamic disk, failed or otherwise, into a basic disk.

Before you begin it is crucial that you back up all of the volumes located on the dynamic disk. Both conversion processes will wipe away all data completely during the transfer.

Conversion Method 1 – Disk Management

Likely the easiest method of the two due to the least effort involved, we’ll begin converting your dynamic disk into a basic disk using the Disk Management tool.

Basic Into Dynamic Using the Disk Management Tool

On the flipside, converting a basic disk into a dynamic disk will not require a data back up. So, if for some reason you feel the need to revert the dynamic to basic change, it’s as simple as following an on-screen Wizard.

You may receive a warning when attempting this change. The first informing you that the installation of an operating system from a volume that is not the current boot volume, will not be possible. This means that you already have a data or system partition set on the basic disk and should not convert. It would be better to dual boot if you’re dead set on using a dynamic disk.

Conversion Method 2 – Command Prompt

If you happen to be more familiar with the Command Prompt, this one may be easier for you. Though, it does require one additional step to that of the Disk Management tool. Regardless, the end result will still be a basic disk converted from a dynamic disk.

Start off by running the Command Prompt. You can do this by typing cmd into the taskbar search and running the result as administrator. 

While in the Command Prompt window, perform the following command:

You should receive a similar confirmation message indicating that the disk has been selected.

You will now need to preview and delete each volume located on the disk, one at a time.

Type detail disk# where the # is the actual number of the disk selected.

Now type select volume #.

Then delete volume #.

Once every volume has been deleted, you can convert the dynamic disk into a basic one by typing convert basic.

Basic Into Dynamic Using The Command Prompt

Follow the above steps up to the part you retrieve a list of available disks in DISKPART. In this process, you won’t have to delete anything. Simply execute convert dynamic and the disk will do so.

Fix Disk Management Errors On Windows 11/10

Disk errors are one of the most common errors on Windows 11/10. It is also scary because all our data are on the disk drives, and even with backup in place, its time consuming to restore all of them. That said, most of these disk errors can be resolved, and this is exactly what we are going to talk about in this post. Check out the best tips for troubleshooting common Disk Management error messages on Windows 11/10.

Fix Disk Management errors on Windows 11/10

This post will help you fix Disk Management errors like:

A disk’s status is Not Initialized or the disk is missing,

A basic or dynamic disk’s status is Unreadable,

A dynamic disk’s status is Foreign,

A dynamic disk’s status is Online (Errors),

A dynamic disk’s status is Offline or Missing,

A basic or dynamic volume’s status is Failed,

A basic or dynamic volume’s status is Unknown,

A dynamic volume’s status is Data Incomplete,

A dynamic volume’s status is Healthy (At Risk),

Cannot manage striped volumes using Disk Management or DiskPart,

Disk Management cannot start the Virtual Disk Service.

Before we start, remember two things. First, you need an account with administrator privileges. Second, be very very careful using the disk management tools. One mistake, and you can lose all your data, and there is no way to undo things without losing the data on those drives.

To open Disk Management tool, follow the below steps:

In the Run prompt, type compmgmt.msc, and hit Enter.

This will launch the Computer Management console.


I am assuming that your drive is properly connected to the PC, and if it’s an external drive, it is connected properly to the USB port.

Make sure to check this before starting, and always try connecting to another PC to see if it works there.

If the device works on another PC, try running the Disk Error Checker.

A disk’s status is Not Initialized or the disk is missing

Many a time your partition or drive does not appear in File Explorer. To check if it’s physically there, open the Disk management. Check if you see it as Not Initialized. If yes, then it simply means that the disk doesn’t have a valid signature, i.e., it’s not properly registered with the system. A disk is registered when you format it at least once. If the disk was available before, then it’s probably corrupted somehow.

If it is a new drive, you can simply initialize it; however, if that’s not the case, we need to try other solutions.

Bring it Online & Add Drive Letter:

Lastly, you can choose to format it in either NTFS or FAT32. If you are using 64bit, make sure to use NTFS. This will remove all the data from your disk.

Check Device Manager for issues.

It is possible that because of driver issues, the hard drive is not working properly. It’s always a good idea to check on the Drive Manager to see that the drive listing has a yellow exclamation mark next to it. If that’s the case:

Similar: All options greyed out in Disk Management.

A basic or dynamic disk’s status is Unreadable

If you are facing this problem, the chances are that your hard drive has experienced a hardware failure or some irreversible corruption. It is also possible that the system’s disk configuration database might be corrupted, and the error message you will get in that case is ‘Unreadable’. You can try it on some other computer, but replacing your hard drive is the only solution here.

Read: SSD not showing up in Disk Management or BIOS in Windows.

A dynamic disk’s status is Foreign

When you move a dynamic disk from one computer to another, you will get a warning icon next to it with Foreign status. Dynamic disks offer the ability to create fault-tolerant volumes that may even span multiple disks – which Basic disks cannot. When you create a dynamic disk, the configuration disk is stored on all dynamic disks, and the information of who owns is lost when switching between PCs.

Now that you know of Dynamic Disk, here is the list of errors, and their solution around Dynamic Disk.

A dynamic disk’s status is Online (Errors) A dynamic disk’s status is Offline or Missing

To bring a disk that is Offline and is still named Disk # (not Missing) back online:

Try to Reactivate Disk to bring the disk back online

Check-in Event Viewer if you have an error that says “No good config copies”. If yes, the Microsoft Product Support team might help you.

Try connecting to another computer, especially with that which has dynamic disks. If it gets online, import the disk on that computer, and bring it back to the PC on which it wasn’t working.

A basic or dynamic volume’s status is Failed

That said, if the dynamic volume is a mirrored or RAID-5 volume with old data, bringing the underlying disk online will not automatically restart the volume. You will need to bring the other connected disks online first, so it makes sure the data is in sync, and then restarts the mirrored or RAID-5 volume manually, and then run the Error-checking tool or Chkdsk.exe.

A basic or dynamic volume’s status is Unknown

In this state, the boot sector of the volume is corrupted, and the data is no longer available. It is also possible that the new disk setup wasn’t complete. To resolve, you need to Initialize it again.

In Disk Management make sure to check if the status is Online, else you need to bring it online first.

After the wizard completes its job, you should have access to it.

A dynamic volume’s status is Data Incomplete

Windows 10 supports multi-disk volume. If you have removed one of the disks and moved it to another computer, it will not work, and will also destroy all the data unless you move and import the remaining disks that contain this volume.

So the solution is to move all the disks which are part of the multi-disk volume to the computer and import it. The disks will be marked as a Foreign disk. We have already stated above on how you can import, and activate those disks.

A dynamic volume’s status is Healthy (At Risk)

If one of your dynamic volumes is marked as at Risk, even if they are healthy, it indicates that there are some IO errors on the underlying part. It could be because of the one on the disk, but it makes all the volumes are Risk. One of the disks must have gone offline.

To resolve this, you will need to bring back the disk to Online Status, and it will restore the status, but if that doesn’t work, you will need to replace that disk

Cannot manage striped volumes using Disk Management or DiskPart Disk Management cannot start the Virtual Disk Service

This usually appears when the remote computer is blocking the Virtual Disk Service (VDS) because of the Firewall or the remote computer doesn’t support VDS at all. VDS service allows one to remotely connect to another computer Disk Management tool, and then let the admin configure it.

You can either configure Windows Defender Firewall to enable the Remote Volume Management Exception or remote login to that computer and then use Disk Management.

How To Deal With Wsappx – Reason For High Disk Usage

How To Deal With Wsappx – Reason For High Disk Usage What is Wsappx?

You can see this process by following the path below –

Wsappx consists of two services –

1. AppXSVC (Appx Deployment Service)

This service is responsible for installing, updating and uninstalling Microsoft store apps. It enables Windows 10 PC to automatically update such as email apps or paint.

2. ClipSVC (Client License Service)

In plain and simple terms it is required for providing infrastructural support to the Microsoft store. If it is disabled, the apps that you have installed from the store will not function properly. This is the Windows background process that sees that the apps that you have installed or paid for are licensed.

How to Fix High Disk Usage Issue Caused By Wsappx?

Wsappx does take a considerable toll on CPU and is therefore accountable for high disk usage. Now, you might come to a conclusion that any processes that take a toll on disk usage should be removed without further ado. Wait before you disable wsappx Windows in 10. That’s because the moment you’ll try to get disable wsappx Windows 10 in the task manager, you’ll see a message warning you about the repercussions.

Your system could become unusable or shutdown abruptly. You may even lose some critical data especially if you haven’t saved it.

So, here’s you can deal with it.

Easiest and the best ways to prevent Wsappx from causing high disk usage – 1. Update Drivers On Your Windows 10 PC

High disk usage can be tackled by updating all the faulty drivers.

If you take the manual route, you would first have to identify the drivers and then exhaust a considerable amount of your precious time in searching for vendors by visiting from one website to another.

2. Stop Microsoft From Manually Updating Apps

Follow the steps and prevent Microsoft store from manually preventing apps

1. Launch Microsoft store

3. Disabling Microsoft Store Using Group Policy Editor (gpedit)

Disabling Microsoft store might sound awkward to some, but it may help prevent Wsappx from high disk usage. To disable Microsoft store, follow the steps mentioned below –

1. Open run command by pressing Win + R

2. Type chúng tôi in the search box that appears

7. You will now be required to restart your PC

4. Scan Windows PC for Viruses

One way to prevent Wsappx from causing high disk usage is by checking the Windows PC for viruses. With Windows 10 you can use the inbuilt Windows Defender security/ Windows Security to perform a full-fledged scan. Once the scan reverts with malicious programs, you can uninstall or fix them.

Or, you can choose from amongst some of the best antivirus software available.

10 Ways To Increase Hard Disk Speed On Windows

Have you ever thought that your PC is taking a long time to boot compared to when you bought it for the first time? Well, any storage devices will get slower as they run out of disk space.

So, your Hard Disk Drive (HDD) or Solid State Drive (SSD) performance, usually speed, will decreases eventually if you have a lot of data stored in them.

Therefore, to avoid this, we are here to present you with an article on increasing disk speed. So, without further ado, let us get right into it.

Whether you are using an SSD (Solid State Drive) or an HDD, it will not perform as it used to. If you use both, you can see that an HDD suffers from this issue a lot more than SSD. Meaning that your HDD has a shorter life span compared to SSD.

Temporary files

Bad sector on HDD

Multiple Background application

Physical issues with mechanical parts

Disk low on space

An HDD’s read and write speed depends on the RPM of the disk. A Hard Disk Drive with a higher RPM (Rotation Per Minute) will perform a lot faster than a hard disk with a lower RPM. 

So, it should be noted that these methods mentioned below do not actually increase your hard disk’s storage. These solutions only perform necessary measures to achieve higher read and write speed.

The methods mentioned below will work whether you have an HDD or SSD. 

Write caching is an impressive feature that Windows offers. It helps improve your storage device’s performance. Enabling write caching on a storage device enables the RAM, or the physical memory, to collect write command, which is then sent to the storage device.

However, enabling this feature can cause data corruption or, worse case, data loss if the device suffers from a power outage while performing read or write.

Please follow these steps to enable Write caching.

When the computer stores its data on a Hard Disk Drive, it stores them serially on adjoining sectors, and when you delete them, these data are marked as replaceable. So, when users want to store new data on the drive, it replaces these sectors with new data.

The problem arises when the replaceable sectors are not enough to store huge files. When this happens, the OS uses a different sector on the drive to store data, which results in a single file being scattered across the drive.

So, when the OS wants to run the said file, it needs to collect data from across the entire hard drive, and this can be a painful task. This is where defragmentation or optimization comes in. 

What de-fragmentation does is it arranges all this data so that the hard disk can access them with ease. In short, defragmentation re-organizes files scattered across the HDD.

Please follow these steps to perform defragmentation or optimization. 

You can only perform disk defragmentation on Hard Disk Drive, or HDD. SSD, however, uses a function called TRIM, which deletes useless data so that it has storage available for new data.

One downside to using TRIM would be that you cannot perform data recovery, as it completely erases blocks of data.

If you have a hard disk that is performing poorly you can run the chkdsk command. The chkdsk, or the check disk, feature in Windows checks your storage devices for any bad sectors and tries to recover and repair these sectors.

You can follow the steps mentioned below to run the chkdsk command.

Replace [volume] with the drive you want to run chkdsk on. If you want to check all your drives, you can simply run the command without mentioning any drives.

/f :Fixes any errors found on disk.

/r :locates bad sector and tries to recover data from them.

When you uninstall an application, it will leave some unwanted files that will take up some space on your storage device. Besides this, temporary files also contain necessary Windows files that help the PC run smoothly when running certain programs.

However, these files can get huge and take up a bunch of space slowing down your hard disk. Therefore, deleting them would be the best option.

Please follow these steps to delete temporary Windows files.

Press the Windows + R key simultaneously to open Run.

Type temp and press Enter to open temporary files location.

Press Ctrl + A to select all, then press Shift + Delete to delete them permanently. 

If it cannot delete files because it is currently in use, you can skip these files.

Again, open the Run windows and type %temp% and press Enter.

Now, permanently delete all files inside it as well.

If your computer runs out of physical memory, or RAM, it uses resources from the hard disk. Meaning that it takes some amount of storage. 

When the disk is already low on space, and on top of that, the PC uses the remaining space as virtual memory from the hard disk, its speed will take a hit. This in turn will lower disks performance.

So, if you are low on disk space, it is recommended that you disable Virtual Memory/Paging.

Please follow these steps to disable paging

Windows offers a utility named disk cleanup that scans your storage device for any unnecessary temporary files and removes them. This, in turn, will boost your hard drive’s performance.

You can follow these steps to perform a Disk Cleanup.

Over time, your computer will collect many unwanted files, folders, and applications. If you want outstanding performance out of your system, it is recommended that you perform a thorough system check and delete any duplicate files and unused applications.

Please follow these steps to uninstall an application.

Open Control Panel.

Make sure that you set View by to Large icons, then select Programs and Features.

Scroll through the list and uninstall any unwanted applications.

Dividing your storage device into multiple parts will make it easier for the PC to access data. Information stored in these partitions is also more organized than storing everything in one huge drive.

Please follow these steps to partition your drive.

When creating a new drive, it should be noted that the drive size should be relatively small to maximize performance.

We also have an article containing various other details on Partitioning a drive. You probably will find it an interesting read.

When the power supply to the hard disk suddenly stops, the sector it read at the moment of a power outage can get corrupted. This can also result in a gradual decrease in performance.

Using a UPS is a great way to prevent your PC from turning off abruptly.

If you have the Operating System installed on your Hard Disk Drive, your PC’s boot-up time will be a lot higher. Furthermore, over time your PC will take even longer to boot due to hard disk mechanical issues. 

So, if you want to increase your disk’s read and write speed, it is always recommended that you use a Solid State Drive. 

SSDs read and write speeds can get 500 to 600 Mb/s higher than their counterpart, HDDs. Besides this, SSD is compact and does not have any moving components, making them a lot more efficient at retrieving the data.
