Disk error My Book Live Duo

Hello.
I have a My Book Live Duo 3tb.
The problem is that one of the two disks  is giving errors.
The discs are WD30EZRS and on page WD, i have found only this, WD30EZRX. I will have a problem if I would change this disk?, Can I change both of them?
Thanks.

Check with WD and see if your Duo is still under warranty.   If so, they’ll send you a compatible drive.

Yes, you can change both drives, but do NOT try to replace them both at the same time or you’ll wind up with a useless box  (the firmware is stored on the hard drives.)

Thanks, that’s what I had in mind, one first and then the other.

I have found on the web WD, nas second selector compatibility support this drive: WD Red WD30EFRX.

My doubt is that the manual accepts only the green disk.

What is your opinión about this?.

Regards.

The Red drives will work fine.
