"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What you're pointing at are not data stores but virtual HDDs.  Your Hard Disk 1 is in VM-Storage datastore and Hard Disk 2 is in data-stor001.

You have virtual disks on different datastores, not virtual machines on different datastores. This is completely normal, just have good documentation as to what VM disks are on what datastores.

Check the properties of EACH Virtual Machine disk....

it will show which disk is on which datastore....

from your screenshot

Hard Disk 1 is on datastore VM-Storage
Hard Disk 2 is on datastore Data-Stor001

but, if you are asking the relationship between OS Volume and Virutal Disk

e.g. which is C: and D:..... this is akwward... usually Disk 0 - its the 1st, Disk 1 is the 2nd, but not always....

You could re-size disk1 by 1GB.....check in Disk Management, which has the unallocated space....

The best thing to do, is run, the following application RV Tools, which will show which VMDKS are orphaned...
Cool tool! Good one Andrew!

Your awesome Andrew! Ok, so to confirm, using the tool. Under the 'Path' column, i see where the .VMX files are. So that is the path that the powered on VM is currently using, correct? Pic for clarification.
