Get-PhysicalDisk

S.M.A.R.T情報を取得しているんですかね

PS1> Get-PhysicalDisk | `
       Select-Object FriendlyName,MediaType,OperationalStatus,HealthStatus

FriendlyName            MediaType OperationalStatus HealthStatus
------------            --------- ----------------- ------------
SKHynix_HFS512GDE9X081N SSD       OK                Healthy

OperationalStatus - 物理ディスクの動作状態

値	意味
Unknown	状態が不明
OK	正常に動作
Degraded	いくつかの問題が検出
Pred Fail	故障が予測される
Error	エラーが発生
Non-Recover	障害が発生し、回復不可
Starting	開始処理が進行中
Stopping	停止処理が進行中
Service	サービスが停止
No Contact	接触がない

HealthStatus - 物理ディスクの健康状態

値	意味
Healthy	正常な状態
Warning	いくつかの問題が検出
Unhealthy	エラーまたは障害が発生
Unknown	状態が不明

Get-PhysicalDisk の結果をcsvに出力

$folderPath = "c:/Users/end0t/tmp"
$fileName = "{0}_{1}_pc_health.csv" -f (Get-Date).ToString("yyyyMM"), $Env:USERNAME
$filePath = Join-Path -Path $folderPath -ChildPath $fileName

$date = Get-Date -Format "yyyyMMdd"
$hour = Get-Date -Format "HH"
$username     = $env:USERNAME
$computername = $env:COMPUTERNAME

# CSVファイルに追記するためのプロパティを定義する
$properties = @(
    @{Name="Date"             ; Expression={$date}},
