Brief Introduction of Dynamic Disk

You had better to know dynamic disk before creating a backup of dynamic disk in Windows 7. The disk can be divided into basic disk and dynamic disk. Most of PCs use basic disks. Basic disks are limited with the 26 letters, and it can only up to four primary partitions. Dynamic disks are different with basic disks. They can be named as volumes and they include RAID-5, mirrored, striped, spanned and simple volumes. Dynamic disks provide the users with more functions than basic disk can give. For example, dynamic disk has more than four primary partition, which is more flexibility than basic disks. 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 that we cannot solve by Windows OS. Once, a user told me that He had a 500GB USB and it was made into dynamic hard drive on Windows 7. It could import the external disk normally under Windows 7, while it could not import the external disk under Windows XP. The dynamic hard drive became invalid. Why? This is because the Windows OS Home editions don’t support them. To solve the question, you have to convert the dynamic disk into basic disk. However, the data may lose or broke while convert the dynamic disk into basic disk. In order to ensure data safe, you must backup dynamic disk on Windows 7 first.
