Removal of the Driveletter C not working when bound to Cardreader

[marcohald]

Describe the bug
The Driveletter C was assigned to the empty Card reader and was not deletable via the line

OSD/Public/Disk/New-OSDisk.ps1

Line 282 in 9bb7639

Get-Partition -DriveLetter 'C' | Set-Partition -NewDriveLetter (Get-LastAvailableDriveLetter)

The Problem is that the Get-Volume CMDlet return a Object but it can't be consummed by the Get-Partition CMDlet
The Partition for the OS was not created via Start-OSDCloud -ImageFileUrl $imageUrl -ZTI and the Recovery Partition was the Size of the Remaining Space

I tried to change the Driveletter via WMI but that didn't work either

$drive = Get-WmiObject -Class win32_volume -Filter “DriveLetter = ‘c:'”
Set-WmiInstance -input $drive -Arguments @{DriveLetter=”Q:”}

Expected behavior
clear the letter assignment

Additional context
As a workaround I have added the Line &mountvol C: /D to my script

Thanks, I'll see how I can add a check for a C: Drive and remove it like I am doing with the USB Drive Letters. Can you run a Get-Volume for the Card Reader?

At the moment i don't have access to a device with this problematic card reader.
But as written before
The Problem is that the Get-Volume CMDlet return a Object but it can't be consummed by the Get-Partition CMDlet
As far as I can remember the mountvol.exe was the only way that can handle the cardreader without an inserted card

This issue has been around for ages in different OS deployment scenarios. :) Especially when the HDD/SSD is not partitioned.
I just recently started trying out OSDCloud and just wanted to add my 2 cents on how we approached this:
Get your hands on the 64-Bit Version of Devcon (might be a bit harder to find, but can be googled) and add:
devcon.exe disable USBSTOR*
and possibly
devcon.exe disable CDROM
To just disable the devices that can "steal" the C-Drive.
