Unable to format additional HDD

My Cloud OS 3 Personal & Network Attached Storage My Cloud EX4
1

I have 3x 3TB Red drives setup currently and have purchased an additional 6TB Red. I have removed the 3 3TB and put the 6TB but format is grayed out in utilities.

Will I be able to use the 6TB along with the 3TB or not because it isn’t the same size?

Thanks.

Hi sarahsarah,

Yes, you can use the 6 TB in JBOD along with the 3x 3TB Red drives. Also, what is the RAID configuration of the my cloud?

RAID5. Any idea why the format button is greyed out?
