I have the EX2 Ultra for about three years. Last night I notice that disk 1 has a red error on it so I pull it out then put it back in, the control panel says it is rebuilding it, now it is green. But now I see it is RAID 1, both disks are green but I dont know if it is really RAID or not. If I try to select RAID 1 it says it will format both disks which will delete all my data. Im confused. I dont even know if Disk 1 is good anymore.
You’ll also get a red light if the disk is good but more than ~90% full.
