How to fix Virtual Disk Service Error
I have a new 4TB external hard drive and tried to make a bootable drive. However, I see there are two parts as unallocated space, each partition is about 2TB, and I can only access the 2TB of it. The option is to create a new partition or the format volume is grayed out when right-clicking the 2nd partition. I know there is nothing wrong with my external hard drive. Now I just want to merge the two partitions as one. So I run the DiskPart command (format fs=ntfs quick label=data) to format but I get an error “Virtual Disk Service Error: the volume is not formattable”
What is the diskpart virtual disk service error?
The Virtual disk service (VDS) is a set of application programming interfaces (APIs) that provides a single interface for managing your storage devices such as creating or deleting, formatting volumes, assigning drive letters to volumes, converting a basic disk into a dynamic disk, and so on. It is supported on Windows server 2003, Windows Vista and later.
The components working with virtual disk service include the Disk Management snap-in, the DiskPart command-line tool, and the DiskRAID command-line tool (Diskraid.exe).
