不同語系(locale) 的Diskpart.exe的輸出格式會有些許不同,下面Code是我在Windows 8.1中文版試過可行的,若要英文版請參考上面連結

Function GET-DISKPARTINFO()

[cmdletbinding] 
# Build Script for LIST DISK in DISKPART

add-content -path listdisk.txt "list disk" 
$listdisk=(diskpart /s listdisk.txt) 

# Get Total Disks outputted.   
# Yes.  It's as simple as "Count the lines on the screen" 
 
$totaldisk=$listdisk.count-8 

# Step through each line that will contain disk information 
for ($d=0;$d -lt $totaldisk;$d++) 
{ 
# Pull the Partition size data and the DiskNumber 
 
$size=$listdisk[8+$d].substring(25,9).replace(" ","")
