Part 2: How to Repair an Invalid Dynamic Disk Without Data Loss

1. What Is a Dynamic Disk

A dynamic disk is a logical disk that is upgraded from local hard drives on the Windows OS. It is capable of using multiple hard disks as well as splitting and duplicating data. It can contain up to 2000 additional and independent partitions and volumes. In a dynamic disk, your data storage is divided into volumes rather than partitions. Besides, using a dynamic disk, you can make volume changes without having to restart the OS and losing important data.

2. Reasons for Dynamic Disk Invalid Problem

Major causes of an invalid disk status are usually three. They entail the following:

• Corrupted partition table – A partition table is present in your desktop PC and laptop and it is the component that keeps the records of your disk partitions. This table could get corrupt owing to a serious malware and virus attack or a human error. If the table gets corrupt, the dynamic disk will appear "Invalid" and there will be data loss.
• Windows Registry defects – A computer's Windows Registry is a core area with nearly every important detail about your PC. If a single registry file develops a defect for whatever reasons, the dynamic disk could become invalid. This could cause data loss.
• Reinstallation of an Operating System – When altering your current OS from Windows to Mac or from Mac to Windows, an invalid disk error could result. This may happen if your OS does not accept dynamic data storage. The same error can emerge when you are upgrading from a lower OS version to a higher OS version.

Other triggers include wrong Bios settings, conflicting software, hardware faults, OS problems, partitioning mistakes, and file system boot sector damage among others. In all the above-mentioned cases, data may get lost or deleted. But this is not as bad as it sounds. You can restore your files regardless of their formats with a hard drive recovery software tool.

3. How to Convert Dynamic Disk to Basic Disk Without Losing Data

If your hard drive appears as a dynamic disk and is in an "invalid" status in the Disk Management screen, you will be cut off from the data in the drive. One of the main ways to solve this problem is to attempt to convert the invalid dynamic disk into a basic disk. As many operating systems support a basic disk, it will be easy to change any dynamic disk you have to a basic one. As you are likely to lose data when performing this act, it is advisable to do a data recovery step with suitable software. After this, follow these steps.

1. Look for Compmgmt.msc in your Start Menu first.
2. Press your Enter key on the keyboard to view Disk Management.
3. Right-click the invalid dynamic disk.
4. From the right-clicking menu, choose Convert to Basic Disk.

4. Reactivate the Invalid Disk via Commands

1. Go to your computer's search bar on the Start Menu. Type "cmd".
2. Next, run the "cmd" as an administrator.
3. A pop-up Command Prompt screen will appear. Type "diskpart" on it and press Enter key.
4. Then, type "list disk". Click Enter key on your keyboard.
5. After that, confirm the number of the invalid disk.
6. Next, type "select disk<disk number>" and hit Enter.
7. Finally, type "online" and press Enter once again.

Final Words

In conclusion, the best way to avoid encountering the dynamic disk invalid status is to dodge the causes. In reality, though, you cannot stay away from some of the causes. It is your computer that decides when to pop up the invalid error. As we noted earlier, the invalid status is sometimes caused by a human error. For instance, you can partition your hard drive wrongly and trigger the widespread invalid disk error. As well, you might neglect your computer's security and privacy by not using a good quality anti-virus tool. The entry of viruses and malware can corrupt your computer's partition table and cause an invalid disk status.

It may be useful to use a Registry clean up tool to maintain the health of registry files as these could cause an invalid disk error when damaged. Once you do everything you can avoid this error and it still happens, follow the methods outlined in this article to solve it.
