Hi guys,

I'm new to Powershell and trying to use it  to manage BitLocker on a Windows 7 machine. I'd like to set a password for access to the data drive (not OS drive). Here's what my current "script" looks like:


Get-WmiObject -Class Win32_EncryptableVolume -namespace "root\CIMV2\Security \MicrosoftVolumeEncryption"
foreach($i in $drives)
{
switch($i.GetProtectionStatus().ProtectionStatus)
{
0 {
$i.ProtectKeyWithNumericalPassword()
$i.ProtectKeyWithPassphrase("MyPasswordHere")
}
1 {
Write-Host "Drive is already encrypted!" }
 }
 }

However, whenever I try to set a password this way I get an error:


+ $i.ProtectKeyWithPassphrase <<<< ("MyPasswordHere")
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : WMIMethodException

What's wrong?

Thanks in advance
