[Seagate BlackArmor 400] Add a disk to Raid 5

[IngoVals]

So my 4 disk bay NAS has only 3 discs, each one two TB in size. I was wondering if you believe it is possible to add the 4th disc to the array without having to start over?

It is setup in Raid 5. I find official support to be almost completely unavailable.

It seems like it is possible, if you believe the marketing spin.

Easy customization.
Seagate offers an array of hard drives certified to seamlessly integrate into the BlackArmor NAS 400 storage server's four drive bays. Simply select the certified drives that are best suited to your business.
A unique cradle system lets you add and swap out the hard drives without shutting down the server or handling a single tool.

You can start by installing one drive then add more to easily increase storage capacity and take advantage of additional RAID configurations. Choose from RAID 0/1/5/10 & JBOD configuration options*.

Of course, before you do anything; backup all the data on the NAS.

Upgrade to the latest firmware and do a reboot and wait about 10 minutes after it boots up before you add the drive.

The last link above is for the firmware and the one before that one is a FAQ.


Do a full backup of your data before you do anything else.
