[问题求助] PowerShell怎样用wmi相关的命令获取硬盘信息？

$systemDriveLetter =$env:SystemDrive # 通常为C:
$diskNumber = (Get-Partition -DriveLetter $systemDriveLetter[0]).DiskNumber
 
# 获取该硬盘上的所有分区
$partitions = Get-Partition -DiskNumber $diskNumber
 
# 计算分区数量
$partitionCount =$partitions.Count
 
# 输出分区数量
$partitionCount
复制代码

@echo off
for /f "delims=" %%A in ('wmic /namespace:"\\ROOT\Microsoft\Windows\Storage" path MSFT_Partition where "DriveLetter='C'" get DiskNumber /value^|findstr "="') do (
  for /f "delims=" %%B in ("%%A") do (
    for /f "delims=" %%C in ('wmic /namespace:"\\ROOT\Microsoft\Windows\Storage" path MSFT_Partition where "%%B" get DiskNumber /value^|find /c "="') do (
      set partitionCount=%%C
    )
  )
)
echo partitionCount=%partitionCount%
pause
