How do i find out what colour drives are inside my "My Books"

[JoeySmyth]

CrystalDiskInfo will give you the info.

example: this is my 3TB My Book

and then google search … WDC WD30EZRX-00DC0B0

Result: It’s a WD Green Drive.

Looking at dis-assembly youtube guides for the 6TB My Book … they are most likely WD Blue Drives and the 8TB My Book’s are probably Reds.
