I've got an external Seagate hard drive (ST3160026ARK) (was my daughters's). She used it back up files from her MAC.
I want to wipe it clean and/or reformat it.

I've plugged it into my Dell desktop (via usb cable) and fired it up. It shows up as a mass storage device, not as an actual drive and I can't see the contents.

How do I go about wiping this?

Thanks
