Native Windows does not support Mac HFS+ partitions. You need to install a third party driver for HFS+ partitions. There are commercial options like MacDrive and Paragon HFS+ for Windows.

i do see it in disk management however it does not allow me to open the volume. The only option available to me is to delete the volume.
I cannot see it in device manager. It just shows the complete drive with no partitions.
I am unable to open it in disk management. I can open the windows partition though.
I am running Win 7 on the Bootcamp partition.
