Here is a tool that will allow you to play with dynamic partitions on your Windows machines.
It is a software called Dynamic Disk Partitioner (DDP), which will allow you to extend partitions or dynamic volumes, but also NTFS volumes on all versions of Windows (Windows 2000, Windows XP, Server 2003, Windows Vista, Windows 7, Server 2008 and Windows 10).
DDP also allows you to move the dynamic disk to another location on the disc, even on another drive, but also to create or expand these RAID-5 volumes.
The RAID 5 uses at least three hard drives and stripes data across multiple hard drives to improve performance through simultaneous access, but unlike RAID 0, RAID 5 includes correction codes (parity bits) between the data,
And if your OS does not support dynamic volumes (like Windows XP), don’t panic since DDP allows you to copy files from these volumes.
Especially since this tool can continue operation of moving volume or adding disk, even after a power failure and without loss of data.
