I just installed the ROG Ryuo 120 water cooler on my ASUS X99-Deluxe II motherboard with an i7-6900K CPU. My OS is Windows 10 Pro x64. Everything is working great, but, I now have a new drive that appeared in Windows Explorer called RYUO (M:). Its properties say it’s a USB Drive with FAT file system and a capacity of 3.73 MB, not so very much. There’s nothing in the instructions about this. Could it be reserved for use by the water cooler itself, or image storage for the OLED display?
