PowerShell硬碟驗證程式-有解無憂

我有一個 PowerShell 腳本來獲取硬碟資訊（如硬碟型別、序列號、大小）。我的想法是我會得到 DeviceID，如果 DeviceID 中的模型名稱有“SSD”。它將顯示這是 SSD，反之亦然。但是，我的腳本很長，重復代碼很多。


##PhysicalDisk_Slot 00

$Disk00 = Get-PhysicalDisk | Where-Object {$_.DeviceID -match ‘0’ -and $_.model -match ("SSD")}

      $DiskSN00 = Get-PhysicalDisk | where { $_.DeviceID -match ‘0’} | Select-object -ExpandProperty SerialNumber
      $DiskSize00 = Get-PhysicalDisk | where { $_.DeviceID -match ‘0’} | Select-object -ExpandProperty Size 
      $DiskSize0 = $DiskSize00 / 1024MB
      Write-Host -fore Green `n `t "Specs: DeviceID: 0"

      }
}


##PhysicalDisk_Slot 01

      }
}

##PhysicalDisk_Slot 02

$Disk02 = Get-PhysicalDisk | Where-Object {$_.DeviceID -match ‘2’ -and $_.model -match ("SSD")}

if ($Disk02.FriendlyName -like "*SSD*")
     {
      $DiskMD02 = Get-PhysicalDisk | where { $_.DeviceID -match ‘2’} | Select-object -ExpandProperty FriendlyName
      $DiskSN02 = Get-PhysicalDisk | where { $_.DeviceID -match ‘2’} | Select-object -ExpandProperty SerialNumber
      $DiskSize02 = Get-PhysicalDisk | where { $_.DeviceID -match ‘2’} | Select-object -ExpandProperty Size
      $DiskSize2 = $DiskSize02 / 1024MB
      Write-Host ""
      Write-Host -fore Green `n `t "Specs: DeviceID: 2"           
      Write-Host -fore Green `t "Specs: SSD Model"               `t`t`t ":"$DiskMD02
      Write-Host -fore Green `t "Specs: SSD Serial Number"           `t ":"$DiskSN02
      if($DiskSize2 -ge 210)
      {
          Write-Host -fore Green `t "Specs: SSD Size"            `t`t`t ": 250GB"
      }
      else
      {
          Write-Host -fore Green `t "Specs: SSD Size"                `t ":"([Math]::Round($DiskSize2, 2))"GB"
      }
     }

else {

      $DiskMD02 = Get-PhysicalDisk | where { $_.DeviceID -match ‘2’} | Select-object -ExpandProperty FriendlyName
      $DiskSN02 = Get-PhysicalDisk | where { $_.DeviceID -match ‘2’} | Select-object -ExpandProperty SerialNumber
      $DiskSize02 = Get-PhysicalDisk | where { $_.DeviceID -match ‘2’} | Select-object -ExpandProperty Size
      $DiskSize2 = $DiskSize02 / 1024MB
      Write-Host -fore Green `n `t "Specs: DeviceID: 2"           
      Write-Host -fore Green `t "Specs: HDD Model"               `t`t`t ":"$DiskMD02
      Write-Host -fore Green `t "Specs: HDD Serial Number"           `t ":"$DiskSN02
      if($DiskSize1 -ge 910)
      {
          Write-Host -fore Green `t "Specs: HDD Size"            `t`t`t ": 1TB"
      }
      else
      {
          Write-Host -fore Green `t "Specs: HDD Size"                `t ":"([Math]::Round($DiskSize2, 2))"GB"
      }
}

結果如下：

     Specs: DeviceID: 0
     Specs: SSD Model            : Samsung SSD 860 EVO 250GB
     Specs: SSD Serial Number    : 
     Specs: SSD Size             : 250GB

     Specs: DeviceID: 1
     Specs: HDD Model            : ST1000DM010-2EP102
     Specs: HDD Serial Number    : 
     Specs: HDD Size             : 1TB

     Specs: DeviceID: 2
     Specs: HDD Model            : ST1000DM 003-1ER162
     Specs: HDD Serial Number    : 
     Specs: HDD Size             : 1TB

在我的腳本中，如何壓縮我的腳本？

這是一種方法：

Get-PhysicalDisk | ForEach-Object -Begin { $i = 0 } -Process {
    Write-Host -Object "`n `t Specs: DeviceID: $i" -ForegroundColor Green
    Write-Host -ForegroundColor Green "`t Specs: SSD Model        `t`t`t : $( $_.FriendlyName )"
    Write-Host -ForegroundColor Green "`t Specs: SSD Serial Number      `t`t`t : $( $_.SerialNumber )"
    if ( ( $DiskSize = $_.Size ) / 1GB -ge 210 ) { $Size = "250 GB" }
    else { $Size = "$( [Math]::Round( $DiskSize, 2 ) ) GB" }
    Write-Host -ForegroundColor Green "`t Specs: SSD Size               `t`t`t : $( $Size )"
    $i  = 1
}

我會使用一個專門的函式來使代碼更簡潔。

function Get-DiskSpecs {
    # create and output an object with the wanted properties
    Get-PhysicalDisk | ForEach-Object {

        # calculate the size. (this does not match the real sizes ???)
        $tempSize = $_.Size / 1024MB
        $size = '{0}GB' -f ([Math]::Round($tempSize, 2))
        if ($_.MediaType -eq 'SSD') {
            if ($tempSize -ge 210) { $size = '250GB'}
        }
        elseif ($tempSize -ge 910) { $size = '1TB'}

        [PsCustomObject]@{
            DeviceId     = $_.DeviceId
            Type         = $_.MediaType     # instead of: if ($_.FriendlyName -like "*SSD*") {'SSD'} else {'HDD'}
            Model        = $_.FriendlyName
            SerialNumber = $_.SerialNumber
            Size         = $size
        }
    }
}

現在，你所要做的就是打電話

Get-DiskSpecs

它回傳一個物件的集合，例如

DeviceId     : 0
Type         : HDD
Model        : ST3500418AS
SerialNumber : 9VMRAT50
Size         : 465,76GB

DeviceId     : 1
Type         : SSD
Model        : Samsung SSD 750 EVO 250GB
SerialNumber : S33SNWDH513210X
Size         : 250GB

但是，我認為您正在以一種非常有趣的方式計算大小，我會選擇另一個輔助函式來格式化給定的位元組大小：

function Format-ByteSize {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory = $true, ValueFromPipeline = $true)]
        [ValidateRange(0, [double]::MaxValue)]
        [double]$SizeInBytes
    )

    $units = "Bytes", "KB", "MB", "GB", "TB", "PB"
    $index = 0

    while ($SizeInBytes -gt 1024 -and $index -le $units.length) {
        $SizeInBytes /= 1024
        $index  
    }
    if ($index) {
        return '{0:N2} {1}' -f $SizeInBytes, $units[$index]
    }

    "$SizeInBytes Bytes"
}

如果你把它放在你的腳本之上并使用它，這個函式Get-DiskSpecs可以縮短為：

function Get-DiskSpecs {
    # create and output an object with the wanted properties
    Get-PhysicalDisk | ForEach-Object {
        [PsCustomObject]@{
            DeviceId     = $_.DeviceId
            Type         = $_.MediaType     # instead of: if ($_.FriendlyName -like "*SSD*") {'SSD'} else {'HDD'}
            Model        = $_.FriendlyName
            SerialNumber = $_.SerialNumber
            Size         = Format-ByteSize $_.Size
        }
    }
}
