How to identify fs volume

I am having difficulty in identifying fs volumes from source disk/diskgroup
to snapshot disk/diskgroup.

Scenario is something like this

  1. C:\ lying on PhysicalDrive1 or TestDg2
  2. Create snapshot of C:, which means take snapshot of physicaldrive1 or
    all the disks in TestDg2
  3. When Fs volumes on snapshot disks are mounted, I need to identify fs
    corresponding to C:\

Any help is appreciated.

thanks
