Adding output from loop to hash table powershell -

i have following code,

#pull number of physical drives $phy = $datafile.getenumerator()|where-object {$_.name -like "*physical*"}  [array]$phydisks = ($phy.name | sort-object )    #for each of these drives work work out physical make of disk $drives= foreach($_ in $phydisks){ $cylinders = $datafile["$_"]["cylinders"] $head = $datafile["$_"]["trackspercylinder"] $sectors = $datafile["$_"]["sectorspertrack"] $bytespersector = $datafile["$_"]["bytespersector"] #convert output gigabites , round the next decimal place $physicaldrivegb = ((([int]$cylinders * [int]$head * [int]$sectors * [int]$bytespersector) /     1024) / 1024) /1024 $physicaldrivesize = [math]::round($physicaldrivegb,1) }    $vmwarefile = @{servername=$servername;memory = $servermemorymb;number_of_processors =              $processorcount;'number_of_cores/processor' = $processorcorecount;number_of_disks = $numberofdisks}  #cadd disk number , size  $vmwarefile hash $i = 0 foreach($d in $drives){ $vmwarefile.add('disk'+$i++, $d) }  

i can't loop through , add results of disk'+$i++ key , $d hash value. there way this?

$count=1 $h=@{} foreach($_ in $phydisks){     $cylinders = $datafile["$_"]["cylinders"]     $head = $datafile["$_"]["trackspercylinder"]     $sectors = $datafile["$_"]["sectorspertrack"]     $bytespersector = $datafile["$_"]["bytespersector"]     $physicaldrivegb = ((([int]$cylinders * [int]$head * [int]$sectors * [int]$bytespersector) /     1024) / 1024) /1024     $physicaldrivesize = [math]::round($physicaldrivegb,1)      $h."disk$($count)" =  $physicaldrivesize     $count+=1    } $h
