Powershell: Get physical drive count and size

I am trying to get size of physical drive on multiple computers. Some computer have 1 physical drive and some have more than 1. I tried this script and it is working fine if i run it locally on one machine.

$s = "machine name"
$counts = GET-WMIOBJECT –query "SELECT * FROM Win32_DiskDrive" -ComputerName $s
$total_disk =  $counts.count
$i = 0
$total_disk = $total_disk -1
$infoObjecta = New-Object PSObject
for(; $i -le $total_disk; $i++){

$a = $i
$a  = GET-WMIOBJECT –query "SELECT * FROM Win32_DiskDrive WHERE DeviceID='\\\\.\\PHYSICALDRIVE$i'" -ComputerName $s
$b = $i
$b = [math]::round($a.size /1GB)


Add-Member -inputObject $infoObjecta -memberType NoteProperty -name "Physical_Disk $i" -value $b

}

OS versions are Win Server 2003, 2008 & 2012.

I am not sure what i am doing wrong. If i run this script locally on that machine or give machine name is $s variable then it is working fine. But if i put remote machine name in $s then it is not giving me output.

I debug and found $counts.count doesn't return any value.

Please advise me how to fix this or any alternate way to get the details of hard drive count and size.

In some version of Powershell if variable is 1 or 0 it doesn't return anything. check if @($counts).count returns the value.
