About dynamic disk

Dynamic disks started to introduce from Windows 2000 onwards, it can offer greater flexibility for Windows Servers and optimize disk I/O performance. On a dynamic disk, you can create volumes that span multiple disks like spanned or striped volumes and create fault-tolerant volumes such as mirrored and RAID-5 volumes. It is more flexible than the basic disk. So some users want to convert basic disk to dynamic disk.

2 Methods to convert to dynamic disk without losing data

To convert a basic disk to dynamic disk, you can make use of Disk Management and AOMEI Partition Assistant Professional.

1. Convert to dynamic disk via Disk Management

In the pop-out window, select the target disk and click on “OK” to confirm this operation and wait for the process to be done. This basic to dynamic disk conversion won’t require you to delete all partitions on the target disk, but it is necessary to remove all volumes when you plan to convert a dynamic disk back to a basic disk someday.
