Phone Flashing/Rooting HTC One - HDD on PC missing

Hi Guys,

I know this is going to sound down right outrageous but this is what happened;

After i rooted my HTC One for some weird reason i have lost my secondary HDD. There is no sign of it in BIOS or on my computer. Has anyone come across this sort of problem before? My PC was working flawlessly till i rooted my HTC One and the next day i started up the PC no secondary HDD.

Any ideas? I used the guide on the HTCOneRoot website.

Also left a comment there to see if anyone can help/assist.

Thanks
