Dynamic disks are a central part of Windows storage management on the Server and XP Professional platforms, but the same features make them so powerful and difficult for conventional disk image software and backups to handle.
Simply speaking, dynamic disks offer more management flexibility without the partition limitation of conventional (or "basic" in Microsoft-speak) storage. Dynamic disks can contain an unlimited number of volumes, but they cannot contain partitions or logical drives.
Volumes in dynamic disks can span several physical disks (spanned disks), or be striped across multiple disks for better performance (in striping, parts of the same file are physically located on multiple physical disk drives). Volumes in dynamic disks can also be mirrored or set up as a RAID 5 array. Dynamic volumes can even be confined to a single disk.
Since you can perform disk and volume operations on dynamic disks without restarting Windows, dynamic storage gives storage administrators a lot of options to deal with the rising flood of data. However, because dynamic disk volumes are usually virtual volumes rather than contiguous chunks of space on a single disk, they pose special problems for backup and especially for disk imaging software.
Dynamic storage is a good-news/bad-news proposition. While dynamic disks offer new powerful tools, they also have some serious limitations that aren't present with conventional disks. Many of these limits are related to backup and restoration.
Dynamic storage can scatter pieces of files across several disks, which means that many conventional disk imaging tools that read blocks off the disk sequentially won't capture a usable image.
Step 1. Launch EaseUS Data Recovery Wizard and select the file types you want to recover. Then click "Next" button to move to the next step.
Step 2. Select the disk where you lost your data and click "Scan" button, the software will quickly scan the selected disk to find all your target files. If you lost your partition, select "Lost Disk Drives" and "Scan" to continue the recovery process.
Step 3. After scan, you can preview all the listed recoverable files one by one and select out those you want. Then, click "Recover" button to get them back once. Here you should save all the recovered files on another disk to avoid data overwriting.
