Dynamic disk is featured with the functions that basic disk doesn’t have, such as create spanned volumes, striped volumes, mirrored volumes, etc. But it doesn’t take advantage over basic disk in compatibility. The dynamic disk becomes invalid in Windows 8 can be a result of incompatible operating system or confliction of different operating system information during importing process.
To put it specifically, all Windows Home versions including Windows 8 Home version won’t support dynamic disk. When your Windows 8 system is Home version, the dynamic disk will show as Dynamic invalid in Disk Management.
Partial information of dynamic disk is saved in system registry, when you connect a dynamic disk to another computer running different OS, you have to import the information of the dynamic disk to system registry; at the same time, system information will be written to the dynamic disk to mark that the disk has been imported. As the information of the different system can be incompatible, your dynamic disk may become invalid in Windows 8 computer.
To fix Windows 8 dynamic disk invalid issue, you can upgrade your operating system to an advanced version that supports dynamic disk. For example, if the operating system is Windows 8 Home version, you can upgrade it to Windows 8 Professional version. Then, you can use the dynamic disk normally.
