Cavalry Dual-Bay Hard Disk Dock - great power comes with great responsbility

I enjoyed the RAID 1 provided by Cavalry Dual-Bay Hard Disk Dock, but I also got burned by that feature today by losing a whole harddisk of content.  So the whole idea is this: be careful by DOUBLE checking the switch before plugging in your harddisk.  Otherwise your secondly inserted harddisk will got wipped and treat as a RAID 1 disk.  You don't want that happen if you have precious content in your second disk.
