foreach($server in $servers)
{
# Get fixed drive info
$disks = Get-WmiObject -ComputerName $server -Class Win32_LogicalDisk -Filter "DriveType = 3";

foreach($disk in $disks)
{
$deviceID = $disk.DeviceID;
[float]$size = $disk.Size;
[float]$freespace = $disk.FreeSpace;

$percentFree = [Math]::Round(($freespace / $size) * 100, 2);
$sizeGB = [Math]::Round($size / 1073741824, 2);
$freeSpaceGB = [Math]::Round($freespace / 1073741824, 2);

$colour = "Green";
if($percentFree -lt $percentWarning)
{
$colour = "Red";
}
Write-Host -ForegroundColor $colour "$server $deviceID percentage free space = $percentFree";
Add-Content "$Env:USERPROFILE\\Desktop\SUBHAG\POWERSHELL\POWERSHELL\server disks $datetime.txt" "$server,$deviceID,$sizeGB,$freeSpaceGB,$percentFree";
