Why this operation is not allowed on the invalid disk pack? Get possible reasons and feasible fixes to solve this issue on this page. Besides, you can also recover data from dynamic disks.
Dynamic disks are a separate form of volume management that allows volumes to have noncontiguous extents on one or more physical disks. Dynamic disks and volumes rely on the Logical Disk Manager (LDM) & Virtual Disk Service (VDS) and their respective features.
These features can help you execute tasks such as changing/cloning disks from dynamic to basic or creating fault-tolerant volumes.
Nevertheless, if your dynamic disk 1 containing important files is marked as invalid and you’re reminded that this operation is not allowed on the invalid disk pack, it can be worrisome.
I had a computer with two 3TB HDDs that were Dynamic Disk mirrors of one another. I’m trying to recover data from one of them without success. So I plugged one of these 3TB HDDs into a USB3 SATA adapter. In Disk Management, this new disk shows as an Invalid Dynamic disk. I right-click on that disk and select Reactivate disk. But I get this error: This operation is not allowed on the invalid disk pack. Does this mean this disk is bad? Moreover, is it possible for me to recover data from dynamic disks? Thanks.
