Question

How to expand the capacity of data drive disks in virtual machines? Will expanding this action result in the loss of data and related authorization in the drive disk?

hi Huang, Winston-HR:

Thanks for reaching out to Microsoft Q&A.

Yes you can increase the disk without any data loss. Only when you try to shrink existing disk there will be data loss.

Unless you use Expand without downtime, expanding a data disk requires the VM to be deallocated. Shrinking an existing disk isn’t supported and may result in data loss. After expanding the disks, you need to Expand the volume in the operating system to take advantage of the larger disk.
