Powershell 檢測USB存儲設備

1.查看存儲設備信息

1.1 Win32_LogicalDisk 獲取本機邏輯磁盤(計算機中顯示的盤符 C: D: E:等)，包括硬盤，光驅，U盤等設備

    Get-WmiObject -Class Win32_LogicalDisk

運行結果

DeviceID --> 盤符

DriveType --> 設備類型

VolumeName --> 卷標

                DeviceID     : C:
                DriveType    : 3
                ProviderName :
                FreeSpace    : 25028714496
                Size         : 232373874688
                VolumeName   : OS

                DeviceID     : D:
                DriveType    : 3
                ProviderName :
                FreeSpace    : 8898105344
                Size         : 9751752704
                VolumeName   : 新加卷

                DeviceID     : F:
                DriveType    : 5
                ProviderName :
                FreeSpace    :
                Size         :
                VolumeName   :

使用 Select * 查看全部信息

eg.

$a=Get-WmiObject -Class Win32_LogicalDisk
$a[0] | Select *

1.2 Win32_DiskDrive 獲取本機物理磁盤信息

Get-WmiObject -Class Win32_DiskDrive

1.3 Win32_PnPEntity獲取本機USB設備信息

Get-WmiObject -Class Win32_PnPEntity | Where-Object { $_.DeviceID -like 'USBSTOR*' }

可以查看 Powershell 檢查設備管理器

Get-WmiObject -Class Win32_PnPEntity 可查本機所有設備

2. Compare-Object 比較差異

alias(別名): compare diff

$a=Compare-Object (1,2,3)  (1,2,4)
$a

InputObject SideIndicator
----------- -------------
          4 =>
          3 <=

3.監聽USB設備的插入和移除

# DriveType

# 3: HDD
# 5: ODD
 
$driverList=@{}  # HashTable  Key-Value
$driveType=@{2="USB_Disk";3="HDD";5="ODD"}   # HashTable  Key-Value
$ErrorActionPreference= 'silentlycontinue'   # 不顯示錯誤, global variable

    $DevPhy_Change = Get-WmiObject -Class Win32_DiskDrive  #獲取物理存儲設備

    if ($DiskPhy_Model -match $par) {
        $DiskPhy_Model=$matches[0]   # 匹配到就賦值給$DiskPhy_Model
    }
    
    $DiskPhy_Size=[int]($DiskPhy_Change.Size /1000/1000/1000)   # 轉化為GB
    $type_num=$Disk_Change.DriveType
    $type=$driveType[[int]$type_num]
