Brand new DNS-323 and 2 x 1.5TB hard drives - Raid Degraded
« on: August 11, 2009, 06:39:19 PM »
Hi all,

I just got the DNS-323 about a week ago, along with 2 x 1.5GB Samsung Spinpoint drives, model # HD154UI

I'm using Firmware 1.07, which was already installed on the unit when it arrived.

The first time around, I did 1TB of RAID 1, and used the remaining space for JBOD ..

After a few days, I heard horrible machine-gun clicking from one of the drives and noticed a pink light.  I logged into the admin and sure enough, I had the dreaded RAID: Degraded message.  Note that I have automatic rebuild off.

Well, I figured maybe the DNS-323 wasn't happy with a mix of RAID1 plus JBOD, so I reformatted both drives and just had 1.5TB of RAID 1...

A couple of days have gone by now, and while I don't hear the dreaded clicks of doom, the status says "Degraded" under sync time again.  I'm currently running a manual rebuild to see what happens.

Does anyone know why this keeps happening?  Mostly, I wanted the DNS-323 to serve as a place to back up all of my PCs to a huge pile of hard drive space, and to serve as a network share for all of my media (mp3, video)... Maybe RAID 1 isn't the best option for this, but RAID 0 seems scary in that one drive failing means I could lose ALL of my data...  Any suggestions on what I should be using would be helpful as well...

Thanks for your time...

You should check the drives with Samsung's disk diagnostics utility

If the drive is the problem, you should get it replaced under warranty.

Thanks for the link.

I imagine there's no way to run that while the disk is in the NAS, right?  I'll have to plug it into a computer with SATA support?
