精简以下代码：powershell -Command Get-Disk 2 Get-StorageReliabilityCounter findstr v i a-zA-Z - find i 2 dssdtxt for f tokens=2 delims= i in type dssdtxt do set powerOnHours=i echo powerOnHours pause

$powerOnHours = (powershell -Command "Get-Disk 2 | Get-StorageReliabilityCounter" | findstr /v /i "[a-zA-Z] -" | find /i "2").Split(" ")[1] echo $powerOnHours pause
