I'm trying to create a Windows 8 to Go USB Drive using a 64 GB USB 3.0 Drive. I'm doing this on Windows 8 Enterprise x64. I am following this MS guide:

Create a Windows To Go Workspace with Powershell Commands

I entered each command on it;s own line, and they work until this command:

$OSPartition = New-Partition InputObject $Disk[0] -UseMaximumSize

I get the error: New-Partition : Not enough available capacity

I went into diskmgmt, and I see that the 350MB partition was created, and that also in diskmgmt I am unable to create any size 2nd Partition on the USB drive that Windows 8 will be installed to.

I know that I am not using the official certified USB Drive, but I still thought I could verify most of these powershell creation commands just using a regular drive, even if it doesn't actually boot into Windows 8 because of whaterver restrictions MS has placed on the OS. Can anyone tell me if they know if the issue preventing the commands from creating the 2nd partition has something to do with the USB configuraiton itself? Is there some type of switch on the USB drive I need to change to enable creating multiple partitions on the same USB Drive?

I see what the issue is now, the RMB (ReMovable Bit) is set for the USB drive to appear as a removable drive so this is the normal behavior.

Thanks for sharing the knowledge.
