WD Sentinel DX4000 Problem

Hello Experts,

I am having trouble with a Western Digital Sentinel DX4000 NAS.  It runs in a RAID10 configuration and I am aware that there need to be a minimum of 4 disks in the array but does anyone know if WD requires them to be WD drives or can I use Seagate for example?  Also, do they all have to be the same capacity?  As it stands right now I have two 3TB and two 2TB rives in there and it gives me an error message while trying to reconfigure the software "Invalid Config."  Just hoping someone has some experience with a Sentinel NAS.  In desperate need of assistance!!  thanks!

Runs in one of two ways,RAID 1 (two disks only ) or RAID 5.

RAID 10 is unsupported.

ok, that's good to know.  Do you know if they have to be WD hard disks or if they all have to be the same capacity?

If you want best performance ,don't mix differing capacities.

The DX ships with their RE4's which are their top of the line SATA drives.

You could use Reds or other nearline from other vendors,but it's your data.

Seagate ES is also a decent drive.

Using cheaper disks ups the error rate tolerance,so that some data can get corrupted or changed.

so I am still having troubles, I have four identical seagate 3TB hard disks in the NAS and I still can't get the recovery to work.  I am still getting an error message saying "invalid config".  Any Ideas???

Make sure the system is patched with the latest firmware.

you may be stuck with WD branded drives,but the good news is there are cheaper ones supported.
