assign
Assigns a drive letter or mount point to the volume with focus. You can also use this command to change the drive letter associated with a removable drive. If no drive letter or mount point is specified, the next available drive letter is assigned. If the drive letter or mount point is already in use, an error is generated.
A volume must be selected for this operation to succeed. Use the select volume command to select a volume and shift the focus to it.
Important
You can't assign drive letters to system volumes, boot volumes, or volumes that contain the paging file. In addition, you cannot assign a drive letter to an Original Equipment Manufacturer (OEM) partition or any GUID Partition Table (gpt) partition other than a basic data partition.
Syntax
assign [{letter=<d> | mount=<path>}] [noerr]
Parameters
| Parameter | Description |
|---|---|
letter=<d> |
The drive letter you want to assign to the volume. |
mount=<path> |
The mount point path you want to assign to the volume. For instructions about how to use this command, see Assign a mount point folder path to a drive. |
| noerr | For scripting only. When an error is encountered, DiskPart continues to process commands as if the error did not occur. Without this parameter, an error causes DiskPart to exit with an error code. |
Examples
To assign the letter E to the volume in focus, type:
assign letter=e
