How to get the list of hard disk on the computer using PowerShell?

To get the list of drives we can use the wmiobject to get the details

PowerShell Code:

Get-WmiObject -Class win32_logicaldisk

DeviceID     : C:

DriveType    : 3

ProviderName :

FreeSpace    : 43298725888

Size         : 255073447936

VolumeName   : OSDisk

We can select the information that we want to display  by using the Select-object

PowerShell Code:

Get-WmiObject -Class win32_logicaldisk | select DeviceID,FreeSpace, Size

DeviceID     FreeSpace          Size

--------     ---------          ----

C:         43306131456  255073447936

H:       1010439315456 2582761172992

X:       2223348092928 3221088104448

Y:       1535164190720 3221088104448

Z:         17846333440   85896196096

We can modify the result to display it in MB or GB along with the decimal digit

PowerShell Code:

$Drive = Get-WmiObject -Class win32_logicaldisk | select DeviceID, FreeSpace, Size

echo "Drive Letter `t Free_Space `t Full_Space"

echo "==========================================="

foreach($Drive in $Drive)

{

$DriveName=$Drive.DeviceID

$DriveFreeSpace="{0:N2}" -f ($Drive.FreeSpace / 1GB) + " GB"

$DriveSize="{0:N2}" -f ($Drive.Size / 1GB) + " GB"

echo "$DriveName `t`t`t`t $DriveFreeSpace`t`t$DriveSize" |Format-Table

}

Drive Letter  Free_Space  Full_Space

===========================================

C:            40.33 GB            237.56 GB

H:            940.99 GB           2,405.38 GB

X:            2,070.65 GB         2,999.87 GB

Y:            1,429.73 GB         2,999.87 GB

Z:            16.62 GB            80.00 GB

You could use the invoke command to get the same details from the remote computer

Invoke-Command -ComputerName Client7-1 -ScriptBlock {

$Drive = Get-WmiObject -Class win32_logicaldisk | select DeviceID, FreeSpace, Size

echo "Drive Letter `t Free_Space `t Full_Space"

echo "==========================================="

foreach($Drive in $Drive)

{

$DriveName=$Drive.DeviceID

$DriveFreeSpace="{0:N2}" -f ($Drive.FreeSpace / 1GB) + " GB"

$DriveSize="{0:N2}" -f ($Drive.Size / 1GB) + " GB"

echo "$DriveName `t`t`t`t $DriveFreeSpace`t`t$DriveSize" |Format-Table

}

}

Clean and Alternative code to view the Hard disk and the free space 

Get-WmiObject -class Win32_LogicalDisk -computername localhost |

Sort-Object -property DeviceID | Format-Table -property @{label ='Drive';expression={$_.DeviceID}}, @{label='FreeSpace(MB)';expression={$_.FreeSpace / 1MB -as [int]}}, @{label='Size(GB)';expression={$_.Size / 1GB -as [int]}}, @{label='%Free';expression={$_.FreeSpace / $_.Size * 100 -as [int]}}

This Code

“@{label='FreeSpace(MB)';expression={$_.FreeSpace / 1MB -as [int]}}”

Will give the column name as for the freespace value and it converts to MB

Drive FreeSpace(MB) Size(GB) %Free
