Quick ping
If you’ve used ping before you’ll know that it normally returns four replies from the target. In PowerShell we have Test-Connection which does the same job. It also normally returns four replies.
When I’m working with remote machines I often want to check they are available before sending a command – especially a WMI command that can take a long time to time out.

foreach {
if (Test-Connection $_ -Count 1) {
Get-WmiObject -ComputerName $_ -Class Win32_LogicalDisk -Filter "DriveType='3'" |
select SystemName, DeviceID, Size, FreeSpace
}
} |
To speed up the process use the –Count parameter on test-connection and only get 1 reply. Quick test to see if he system is there and then run the rest of the code
