Adding a second disk to a My Cloud EX2 Ultra shouldn’t be that hard, should it? And if it is hard, how come I cannot easily find instructions on how I am supposed to do it.
Summary: I have a 6TB drive from my PC that I want to put in my MCEX2U (version 5.24.108). Once the drive is in, it shows up under Storage → Disk Status:
Drive2 6TB 35C Good
But in Storage → RAID even though it says RAID Health: Healthy, it only shows the existing disk:
Volume_1 JBOD 4TB Good
I tried going to Settings → Utilities → Format Disk, but it only shows volume 1.
I also tried Settings → Utilities → System Diagnostics → Quick Test.
In the alerts there is this message:
The data on volume 2 on the drive is not accessible.
Visit the Help Center for support.
I put the disk back in my PC and it is working fine. I used Computer Management → Storage → Disk Management and deleted the single volume (aka partition) just in case MCEX2U cannot format a disk that already has a partition (NTFS or exFAT). I have noticed drives that come out of the MCEX2U have several raw partitions.
I expect most people only put brand new disks in their MCEX2U, so don’t come across this problem. My hope is I need to make my 6TB disk look like it has just come from the factory, but I am unsure how to achieve this.
