How to fix a bad drive

[silver_mica]

Howdy,

I have a Buffalo NAS drive with a red light.  I believe it flashes three times.  Now, I am not 100% sure of the model  -  but I believe it's the Buffalo LinkStation Pro Duo 2.   

So, what do I do?   Buy a hard drive and pop it in (replace the bad hard drive)?    Or, is there a procedure for rebuilding?

NAS Navigator 2 has this to say:

Error:
E30: An error has occurred on disk 1
I12: The RAID array works under degrade mode

I also took a screen capture:

Buy a new disk, put it into whichever bay is show the fault, reboot the unit, log onto the setting page and rebuild the RAID.

So, I take it I'd use NASNavigator to rebuild the RAID?

No, you do this via the settings page. System - Storage - Array1.

I don't know of anyway to access a settings page.  The only thing I know is that after plugging these NAS drives into the network they show up as a network drive (Windows Explorer).  My units are pretty old - are the manuals still around somewhere?

Right click the picture of the Linkstation in the NAS Navigator -> Settings. Have a look through the manual.

Okay, so type the IP address assigned to the NAS in a browser to access the settings page. Or, as you have stated, through NASNavigator 2 right click on the drive icon and select "Open Web Settings"

Helpful tips:
default username and password (if a password has never been setup)
Username: admin
Password: password

Now that I'm in the settings page I can see that DISK 1 is bad (well there's a error with DISK 1).
However when I take apart the NAS unit nothing is marked that I can see indicating which disk is DISK 1 and which is DISK 2.   
I'd guess that the disk on the left is DISK 1 and the disk on the right is DISK 2.

The user manual as found through the Settings Page is fairly general and is written for 4 or 5 different models and I don't see anything in the manual identifying the physical location of DISK 1 or DISK 2.

At this point I could just buy a replacement hard drive and randomly replace one of the two while crossing my fingers, but I was hoping for something a little more solid.   

Should I take the red pill or the blue pill?

Should be the one on the left.

If you shut the device down before removing a drive it wont really matter. If the device doesnt come up it means you guessed wrong, then you can poweroff and switch to the other.

Thanks @1000001101000

I plan to head out to the store today and buy a replacement drive today.  I wonder if this would be a good time to upgrade from a 2TB drive to something larger, say 4TB or even 8TB.
