Vista - Not updating drive listing?

I'm tring to use TrueCrypt with powershell. TrueCrypt is an encryption
program which in my case is encrypting a whole drive/partition meaning
the drive lester only shows up after I run the program. I'm running it
inside powershell, but I can't seem to access the drive unless I restart
powershell. Get-PSDrive shows the drive (O but I can't access it. Is
there a way to get it to refresh or aworkaround without restarting
powershell? Thanks

PS C:\> Invoke-Expression $TCCmdLine | Out-Null
PS C:\> Sleep 5 #give it some time to mount the drive, just in case
PS C:\> Get-PSDrive | Format-Table -auto

What is "invoke-expression $tccmdline" doing?

I would do a remove-item, then re-add with new-item.

$tccmdline contains the cmdline for the truecrypt program, something
along the lines of "TrueCrypt.exe /v \Device\Harddisk2\Partition1 /l O:
/k keyfile /m /rm /a /s /q", this part of the script works fine (no
change if I put the direct program cmdline instead of using invoke).
This program ends up mounting drive O: in windows

I'm not sure what you mean by using remove-item/new-item, but I will try
using remove/new-psdrive and see if that helps.

Yes, sorry, I really meant -psdrive and not -item... I should type what
I mean.
