There's a space (" ") between "list" and "volume". So list disk and list volume, not listdisk and listvolume. That should change the output drastically.

Hi, thank you for your reply. You forget space between list disk and list volume. Command lisTdisk is bad

whoops, whys it bad? ill go again.. cheers Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation. All rights reserved.

Disk 0 is your boot disk, with volumes 3&4 (system reserved and your "C:") Disk 1 is empty it seems. You just need to create a partition on "Disk 1", assign a drive letter, and format it. This can be done in computer management. In diskpart, that would look like this +/- : select disk 1 create partition primary select partition 1 assign format fs=ntfs quick BEWARE : if the disk contained any data, that will wipe it entirely and you will lose your data.

wow thanks heaps! its all so simple now haha thankyou both!shauno
