DNS-323 dead - possible to save the data with another DNS-323?

Hi

I got a DNS-323 where the power LED keeps blinking. I'm not able to access it over the network any more. Reset hasn't helped, either (I suspect it's not even reacting to the reset switch any more). It's got two 1TB disks, configured as JBOD (dumb, I know). When I power the unit on without hard disks the same happens: blinking big LED, no access. To me it looks quite dead. And no, I didn't do anything before it died, last firmware I installed is the official one from d-link's website.

I have a second DNS-323 here (also JBOD...). At the moment, I'm copying the data off to another NAS and was planning to replace the disks with the ones in the dead unit. What do you think, would that work? Thanks for any help in advance, I very much appreciate it!!

Regards
Fermin

If you have the skills try this:

It might be just corrupt firmware but also a hardware error, you can be never sure until you see the output.

Hi

Thanks for the link. Unfortunately, I got two left thumbs when it comes to soldering. What about my other idea, to just place the two disks in an identical unit? Shouldn't that work, too?

Yes - that should, I know it works for RAID and standard volumes, but I have never tried it with JBOD

Re: DNS-323 dead - possible to save the data with another DNS-323?

ok. Keeping my fingers crossed here.... the data from the still working DNS-323 ist still not finished copying, so I still have time looking for alternatives. And yes, I'm copying the data to a NAS with redundancy this time (RAID5 on a Promise NS4300N). I guess if I'd had RAID1 in the DNS-323 I could just have hooked one of the disks up to my PC and copied the data off ...

You can do that with JBOD too, I think. Connect both drives to your Linux PC, and execute

Code:

sudo mdadm --assemble /dev/md0 /dev/sdb2 /dev/sdc2
sudo mkdir /mnt/jbod
sudo mount /dev/md0 /mnt/jbod

You should be able to read the array in /mnt/jbod

Re: DNS-323 dead - possible to save the data with another DNS-323?

Yes well - that's the other problem, got no Linux here. I understand though that there are drivers that could enable me to mount the disks in Windows 7. Or I could probably get a bootable linux on a CD or USB stick and use that.

How do I know the correct order in which to attach the disks to the SATA controller? In other words, is the left disk "/dev/sdb2" and the right disk "/dev/sdc2"?

You cannot mount a JBOD disk in windows, even with the ext2 driver. use e.g. a Ubuntu or SuSE Live CD/DVD. To check how the devices are called you can consult " dmesg | grep sd ". the order of the devices doesn't matter. the md driver will handle this for you.

cool, thanks!! What would you suggest I try first - putting the disks in the same order in my other DNS-323, or use a Linux?

i'd use linux if i had a desktop with 2 SATA ports. but i'm familliar with it. Not sure what is the best solution for you.

An additonal point would be that the risk of data loose is much lower in a real linux. if you look around the forum there are many posts with "accidently formats" because of unexpected behavoir of the stock firmware.

You're probably right. As for the two SATA ports, not sure I have them, but I've been wanting to get me a "docking station" (e.g. http://www.ssi.com.tw/product_content.aspx?id=31) for some time now. Guess this is the right time...

ok, so the data finished copying. I'm going to use UNetbootin to create an Ubuntu Live USB stick. As I said before, fingers crossed ... :-)

Re: DNS-323 dead - possible to save the data with another DNS-323?

damn ... or not. It turns out the interface I bought doesn't work with the hard disk(s). They sold me the wrong one, I needed SATA-II, got one for SATA/IDE (dumb me for believing them and not checking). But ... I called D-Link's support and asked if it should work anyway with replacing the disk. And yes, it is supported, provided the replacement is configured identially. Which it is. I went ahead and it works :-) :-) :-) All my data is there, and I'm copying it off to a network location right now.

Do you mean PATA/IDE? A SATA-I connector should work fine with SATA-II disks.
