So far we’ve looked at creating a single partition on a disk. This time we’ll look at how you can create multiple partitions on a disk. The are good reasons not to do this but its something I’ve seen done on a frequent basis.
Lets create a 20GB disk as an example and mount it
New-VHD -Path C:\test\Test1.vhdx -Dynamic -SizeBytes 20GB Get-VHD -Path C:\test\Test1.vhdx | Mount-VHD
Initialise the disk
Initialize-Disk -Number 1
Now we can create some partitions
New-Partition -DiskNumber 1 -DriveLetter F -Size 5GB New-Partition -DiskNumber 1 -DriveLetter G -Size 5GB New-Partition -DiskNumber 1 -DriveLetter H -Size 5GB New-Partition -DiskNumber 1 -DriveLetter I -Size 4.87GB
The reason that the last partition is only 4.87 G is that 128MB of disk space is reserved
PS> Get-Partition -DiskNumber 1 | Format-Table -AutoSize
DiskPath: \\?\scsi#disk&ven_msft&prod_virtual_disk#2&1f4adffe&0&000003#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}
PartitionNumber DriveLetter Offset Size Type
--------------- ----------- ------ ---- ----
1 17408 128 MB Reserved
2 F 135266304 5 GB Basic
3 G 5503975424 5 GB Basic
4 H 10872684544 5 GB Basic
5 I 16241393664 4.87 GB Basic
You can format the 4 new volumes in one pass
Get-Partition -DiskNumber 1 |
where Type -ne 'Reserved' |
Format-Volume -FileSystem NTFS -Confirm:$false –Force
PS> Get-Partition -DiskNumber 1 | Get-Volume | select DriveLetter, FileSystem, Size
DriveLetter FileSystem Size
----------- ---------- ----
H NTFS 5368705024
G NTFS 5368705024
I NTFS 5229244416
F NTFS 5368705024
The Storage module can be used to simply and easily create multiple volumes on a disk
