Brief Introduction to Dynamic Disk

You had better to know dynamic disk before creating a backup of dynamic disk in Windows 7. Generally, disk can be divided into basic disk and dynamic disk. Most of PCs use basic disks. Basic disks are disks that contain partitions, like primary partitions and logical drives.

Dynamic disks are different from basic disks. You can create different kinds of volumes on dynamic disks, such as volumes that span multiple disks (spanned and striped volumes) and fault-tolerant volumes (mirrored and RAID-5 volumes).

Dynamic disks provide users with more functions than basic disks do. For example, they use a database to track information about dynamic volumes on the disk and about other dynamic disks in the computer. However, Windows OS Home edition won’t support dynamic disk. The good news is that it is possible to convert dynamic disk to basic disk.

Why We Need to Backup Dynamic Disk?

Dynamic disk is more and more popular for its flexible features. But we may meet some problems on certain Windows systems. Once, a user told me that he had a 500GB USB and it was made into dynamic hard drive on Windows 7. It could be imported as an external disk normally under Windows 7, while it could not be imported as an external disk under Windows XP.

The dynamic hard drive became invalid. Why? This is because the Windows OS Home editions don’t support dynamic disks. To solve the problem, you have to convert the dynamic disk into basic disk. However, the data may be lost or broken during disk conversion. In order to ensure data safety, you must backup dynamic disk on Windows 7 first.

We can create Windows 7 dynamic disk backup by using the built-in tool, but the operations are confused and complicated. To make it easier, we can run dynamic disk backup with the help of third party backup software like AOMEI Backupper Professional.
