explain: Get-Disk | Where PartitionStyle -eq “RAW” | Initialize-Disk -PartitionStyle GPT -PassThru | New-Partition -UseMaximumSize -AssignDriveLetter | Format-Volume -FileSystem NTFS -NewFileSystemLabel “MYDATA”
This command performs the full setup of a new RAW disk in one PowerShell pipeline:
Get-Disk |
Where PartitionStyle -eq "RAW" |
Initialize-Disk -PartitionStyle GPT -PassThru |
New-Partition -UseMaximumSize -AssignDriveLetter |
Format-Volume -FileSystem NTFS -NewFileSystemLabel "MYDATA"
Full meaning
Find any uninitialized disk, initialize it as GPT, create one large partition, assign a drive letter, and format it as NTFS with the label
MYDATA.
Step-by-step explanation
1. Find disks
Get-Disk
Lists all disks connected to the system.
2. Select only RAW disks
Where PartitionStyle -eq "RAW"
Filters only disks whose partition style is RAW.
RAW means:
The disk is new or uninitialized.
3. Initialize the disk as GPT
Initialize-Disk -PartitionStyle GPT -PassThru
This prepares the disk for use.
GPT means GUID Partition Table, the modern partition style.
-PassThru is important here because it sends the initialized disk object to the next command in the pipeline.
Without -PassThru, the next command may not receive the disk object.
4. Create a partition
New-Partition -UseMaximumSize -AssignDriveLetter
Creates one partition using all available disk space.
-UseMaximumSize means:
Use the full disk space.
-AssignDriveLetter means:
Automatically assign a drive letter, such as E: or F:
5. Format the volume
Format-Volume -FileSystem NTFS -NewFileSystemLabel "MYDATA"
Formats the new partition.
NTFS is the Windows file system.
MYDATA is the volume label/name that appears in File Explorer.
What happens after running it?
A new usable drive appears, for example:
E: MYDATA
You can then store files on it.
Very important warning
This command can erase or prepare disks. Use it only on a new test disk, preferably inside a VM.
Before running it, always check:
Get-Disk
Safer version:
Get-Disk | Where-Object PartitionStyle -eq "RAW"
Then confirm the correct disk before initializing.
