Q: How can I easily see the virtual hard disks for all virtual machines on a certain disk?
A: To see virtual hard disks (VHDs) for virtual machines (VMs), use the Windows PowerShell script below. It lists all VMs, gets the hard disks for those VMs, and then tests if the path of that VHD starts with the desired drive letter, in this case the E:\ drive.
You must have the Hyper-V PowerShell module imported (although in PowerShell 3.0 the import will happen automatically--still, use Import-Module Hyper-V to avoid any possible ambiguity of modules used).
PS C:\> Get-VM | Get-VMHardDiskDrive | where {$_.Path.StartsWith("E:\")}
VMName ControllerType ControllerNumber ControllerLocation DiskNumber Path
