The Humax SD recorders use a proprietary disk format. You need to use special software to read the disk such as Humaxrw; see http://humaxdisk.wikispaces.com/HumaxRW. There is a risk that trying to read the disk on Windows has damaged the Humax partition table if this is the case then you can use HumaxCheck to fix the problem.
Humaxrw can also be found here on the Blog download pages
When you do connect it DO NOT allow Windows (or any other OS) to "initialse the drive"
