G-Technology ext hard disk crashes to blue screen - aswsnx,exe

Hi, my external G-Technology external G|RAID mini is crashing to blue screen quite often when I am trying to access it from the Explorer (to look at the files / folders on it)
During the dump on the bllue screen I can see that it mentions the aswsnx.exe at the bottom, not sure how that all works, but can anyone help here?
Thanks,
Nik C
