When I run DiskPart, I have a Disk 0 and a Disk 1. On Disk 0 there are 3 partitions. Partition 3 has a size of 238 GB.

When I run List Volume there is not a matching volume with a size of 238 GB.

Is there a way to manually create a volume attached to this partition (without deleting the data on the partition!)?

  • What is (what do you suspect is) on this partition? Is the drive from another operating system? – G Koe Mar 20 '14 at 22:31

You need to ASSIGN a drive letter to that partition. Assign assigns a drive letter to the selected partition, making it a 'volume'

Dispart> Select disk 0

Diskpart> Select partition 3

Diskpart> Assign

If there is data on that partition that is readable by windows, you will be able to see it. If windows pops up a message that states, "you need to format the drive in (assigned letter)", you will need to give us more information!

  • I get the following result: "There is no volume specified. Please select a volume and try again." The Assign help text says that it is for the selected volume: "Assign - Assign a drive letter or mount point to the selected volume." From the help text, it seems as if Assign does not look at or care about the selected partition. – Vaccano Mar 17 '14 at 23:15
