Red light on outer case, blue inside on both drives

Can someone help me figure this out? I have a solid red light on the outside, but both drives inside show blue. I can still access the data and it is mounted. Is this warning me that I may have a failure soon? I’ve had this drive for a while, and I believe its RAID1 as its a 12TB drive but shows as 6TB. I can’t figure out how to check that.

Hi @Sadie2705,


Set the system to data protection mode (also known as mirrored mode or RAID 1) and the capacity is divided in half. Half of the capacity is used to store your data and half is used for a duplicate copy. If one drive goes down your data is protected because it’s duplicated.
