HD1 failed on HS-DHTGL/R5 2.14

[deancrane]

My TeraStation (HS-DHTGL/R5) was running very slowly, so I rebooted it.  When it came back up I got these messages on the LCD display.

 

HD1 ERROR E23

 

RAID ERROR E13

 

Operation Mode I12

DEGRADE MODE

 

The green, amber and red lights are on steady on the left side and top right light is red. 

 

I replaced the hard disk (Samsung HD501LJ) with a new unit.

 

I restarted the TS but when I boot I still have all the same errors.

 

I updated the firmware to the latest (2.14).

 

I swapped drive 1 with drive 2 and the problem moved to drive 2.

 

Could I have a DOA drive and/or should I be looking at something else?

 

I've seen a lot of bad reviews for the Samsung drives.  Is there another drive that might be more reliable?

The options are greyed out on the Disk Format menu.  I'm not allowed to select a target.

 

The "Restructure RAID Array" button is also greyed out.  The only option is "Delete RAID Arrary".

 

I see this message near the bottom. 

An error in a RAID Array has been detected.
Select restructuring disk and click `Restructuring RAID Array`.

Did you match the drive specs of the new drive to the specs on the old drives. The new drive needs to be the same RPM speed as the other drives. It also needs to be the same capacity or larger and have the same MB cache or larger.

[deancrane]

The drive is the exact same model as the failed one.  Samsung HD501LJ.  500GB

 

Should I put the Terastation into EM mode first?

[Jotin]

I doubt that that would make a difference but it wont hurt to try. Can you currently access the data?

[deancrane]

No, we can't access the data.  I suspect we have a failed controller.

I swapped the drives into another Terrastation and I get the same messages.  E13 & E23.

[Jotin]

Is it the exact same TeraStation? Which disk does it show the errors for? All of them or just one? If it's just one try rebooting with that drive out of the unit.

[deancrane]

Yes, the exact same model.  I updated the firmware to 2.l4. 

 

I rebooted with the three good drives.  It only complains about HD1. 

 

But now I get and E14 "Can't Mount" as well as E13 "Array Error".

 

I tried to boot with the four original drives, but it still complains about HD1 and gives the same erros.

 

Is there anyway to get that volume mounted again?

[deancrane]

I'm also not sure EM mode is working.  I follow the procedure and see "System EM Booting", but when I launch NASNavigator2 2.43 it doesn't find the HS.  The LCD shows all the normal messages.  I can still connect with the web admin.

 

Should I attempt a TFTP boot?

[deancrane]

None of the previous steps worked. 

 

I put all four drives in a PC with 5 SATA connections.

 

I tried the Disk Doctor XFS Data Recovery, but after several attemps and many hours of scanning, i couldn't get it to see my data.

 

Then I tried the NAS Data Recovery Ver 2.02 product from http://runtime.org and it scanned the drives and showed my data within a few minutes.  I paid the $100 US for the full version and was able to restore all my data.

 

I've now go all my data back and will rebuild that array.
