# Clear-LocalDisk

This function is intended to run from WinPE and is ideally used to clear all Local Disks returned by Get-LocalDisk.  I use this to clear all Local Disks (OS and DATA) before an OS Deployment

## Getting Started

I strongly recommend running it without any parameters.  By default, the following information is presented

```
Clear-LocalDisk
```

1. -Verbose is enabled
2. Detected UEFI and PartitionStyle are displayed
3. Get-Help Clear-LocalDisk
4. Get-LocalDisk | Format-Table is displayed

![](/files/-MUCHEkNWvwj_TDU2wm2)

## -Force

When the `-Force` parameter is used, things are a little different

```
Clear-LocalDisk -Force
```

1. Get-LocalDisk | Format-Table is displayed
2. Confirm for each LocalDisk
3. Get-LocalDisk | Format-Table is updated and displayed
   1. PartitionStyle = RAW
   2. NumberofPartitions = 0

![](/files/-MUCHXrHDmFpdv6qz7jZ)

## -Force -Confirm:$false

This leaves no room for error as there are no confirmation prompts

```
Clear-LocalDisk -Force -Confirm:$false
```

![](/files/-MUCI_RlrMSO1YdTZRnk)

## -Initialize

Adding this parameter will initialize the Disk in either GPT or MBR.  If the system is UEFI, then GPT is automatically enabled

## -PartitionStyle

Using this parameter you can override the automatic selection of the PartitionStyle.  In this example, a UEFI with GPT would have been automatically selected, but specifying `-PartitionStyle MBR` overrode that
