Formatting Disk using DiskPart

Quite a while i’ve not post about Hyper V content.

Let look into several command that you should execute when formatting disk. Wait, won’t it be easy using Computer Management snap in to format a disk.

Well, you’re right but…you will not have Computer Management when Hyper V host machine is install with Server Core version.

Hope this command come to handy when you format a disk either local or iSCSI LUN presented to Hyper V host.

1. Execute Diskpart command.


2. Execute List Disk to view the disk available on the Hyper V machine

DISKPART > List disk


3. We are going to format disk 3. Execute select disk 3 to select disk 3.

DISKPART > Select disk 3
DISKPART > List disk


* indicated disk 3 is selected.

4. If the disk status is offline. Type

DISKPART > online disk

5. View the attribute of the disk. Make sure the disk read-only is not set to Yes.

DISKPART > attribute disk


If mark as Read-Only. Key in below command:

DISKPART > attribute disk clear readonly

6. Create primary partition using the entire disk volume.

DISKPART > create partition primary
DISKPART > list partition


7. Assign a drive letter

DISKPART > Assign letter =K


8. Quick format a disk with NTFS file format

DISKPART > format fs=ntfs quick


That’s all. Easy and simple. This is my last post for 2010. Wishing everyone “Happy New Year 2011”.
