This is a clients drive with the RedOne Camera 4k files….I have it hooked up from the drive by ESATA to Sata on my motherboard. It shows up in disk management but not in my computer? It does NOT give me the option to give it a drive letter. It only gives me an option to make a New Simple Volume in the unallocated space…..I assume his files are in the 931GB Primary Partition? What do I do so I can read these files in the primary partition?
