Unable to wipe drive

Morning All,

I am following setup instructiosn at http://www.techradar.com/how-t…-raspberry-pi-nas-1315968 and the software installed fine and I am now at the point where I scan for disks and it finds my USB atatched drive and then I select to wipe it and I get the error below:

The drive then disapears from the list of Physical drives and I have to refresh it several tiems for it to find it again.

Error #0:

Have you unmounted the drive in order to wipe it?

How do I unmount it?

The drive doesnt show up under filesystems unfortunately. jut tried wiping again and I get this:

if I SSH into the raspberry Pi and issue fdisk -L it gives me the ouput as per the attachment, is the small /dev/sda1 listed as Microsoft reserved causing the problem ?

Hey Mr T,

yes correct the drive was formatted on a Windows machine.

I will give that a try and also grab a powered USB hub from work and try that.

Cheers
