One last look at drives and then we are on to folders.

Listing 4.4 uses the Filesystem object to test if drives are ready.  If you examine the script the majority of it, like a lot of VBScripts is taken up with display.  Using PowerShell's ability to substitute variables into a string we can cut that down and make a much simpler script.

#Listing 4.4
$fso = New-Object -ComObject "Scripting.FileSystemObject"
$fso.Drives | Foreach {
    if ($_.IsReady){"DriveLetter $($_.DriveLetter) has $($_.FreeSpace) of freespace" }
     else {"DriveLetter $($_.DriveLetter) is not ready"   }
}

Get the filesystemobject as before. Pipe the drives into a foreach cmdlet and test on the IsReady parameter.  If the drive is ready it displays the freespace otherwise it gives a message that the drive is not ready.  It does pick up USB drives and memory sticks.
