Hi, I have DNS-323 which has been working with the funplug flawlessly for over six months. (I was using the funplug to allow secure scp and ssh.)

Yesterday, we had a very brief power-cut. I turned the device on again, and all seemed to be working ok...but I think the scp thing was disabled because a backup script I wrote that uses this failed during the night.

I was able to connect to the web interface, get inside, and restart the device, I thought that might fix the problem.

Now...nothing! Upon logging in to the web interface I am asked what RAID configuration I want?!?!!? I can't telnet or ssh to the device!!

I own a laptop and am about to drive to bestbuy to purchase a USB SATA enclosure. I plan to attempt to access my data using some sort of Windows application that reads linux partitions. But I'm not even sure if the data is still there...?

All suggestions are welcome!!

Thanks,

Richard
PS If it makes any difference I was using the mirrored RAID mode (can't remember the number).

Actually I am not a linux expert but it looks like your RAID 1 config is gone. maybe a reassembling of the disks help. If not you could try to boot your pc with a linux from cd (knoppix) to check if the data is accessible

Put a disk in the USB enclosure, hook it up to your laptop and load EXT2IFS - you should be able to retrieve the data.

Now - what does my signature say?????

rtg20 · 2008-07-23 21:21:48

thanks for the replies. I got the enclosure and already tried ext2ifs - it wanted to reformat the drives before i could use them.

currently I'm trying Nucleus Kernel Linux, as recommended by someone else on another thread. it's found two partitions so far, but the second one has a bunch of weird characters for a name...?

The drives themselves don't seem to be physically damaged, but I want my data!

fordem · 2008-07-23 21:51:07

If EXT2IFS wanted to reformat the drives before you could use them, your data is either already screwed - or - you're not using it right. Personally - I've never had the need to use it for data retreival, however, I have used it, with disks from a RAID1 DNS-323, for no other reason than to verify that it was a usable method of "emergency data access".

rtg20 · 2008-07-24 00:15:08

Currently I'm trying DiskInternals Linux. It's still scanning the drive, it says it's found files but i'm not sure whether or not they'll be recoverable. I tried Nucleus Kernel Linux but it gave weird results, found some files but gave weird partition names for the Linux partitions. Anyone heard of anything like this...?

If DiskInternals doesn't work I will try Nucleus Kernel Linux under Windows XP (am using Vista at the moment).

I admit I was confused between backup and redundancy...! Once i have sorted this out i plan to backup my photos using a SmugMug Pro account as my photos are my only data I really care about. Fortunately I think I have all of them backed up on a server owned by a former employer, I just called a former colleague and he confirmed my directory was still full of stuff. Also I will buy a UPS for my DNS-323...

It SUCKS that something as simple as a power-cut could be so devastating! Over the years my laptop machines have suffered power-cuts without any problems. (No, I wasn't using the battery...)

fordem · 2008-07-24 00:33:51

If it's any consolation my DNS-323 has sustained a few dozen power outages and abrupt shutdowns with no data loss - it's just the luck of the draw, although I believe if you were writing to it at the time of the power failure that could do the trick.

BTW - how do you use a laptop and not use the battery - unless you go to the extent of removing the battery, it is always there, always present and available in the event of a power outage.

rtg20 · 2008-07-24 00:38:47

I take the battery out, if you leave it in all the time (and run off AC power) you just wear it out. But maybe I should replace it, in case of another power cut!

bq041 · 2008-07-24 01:29:51

Just so you know, if you run you laptop without the battery, you wear out (overheat) the charger and motherboard. Most laptops use the battery as a regulator/filter because it is easier and cheaper than building one into the charging circuit. You'd be better to leave it in and cycle it every now and then.

rtg20 · 2008-07-24 01:32:59

Really...? I've never had a problem with a laptop charger/motherboard. But I've known lots of people who wear their batteries out by leaving them in all the time such that the thing is worthless (and expensive to replace).

So what do you think...? Leave it in all the time but run it down flat once a month...?

bq041 · 2008-07-24 01:34:44

On another note, do you have another hard drive you can put in the DNS? If you do, set it up and install telnet and USB access (probably use ffp). Then connect the USB drive to the USB port on the DNS.

I also had issues with ext2ifs on my Vista Machine. It would assign a drive letter, but would still always want to format it. It was as if the ext2 module was not inserted into windows. Anyway, why not try mounting it on the device which wrote it. The DNS can also prompt for formatting in the web when the config files or partitions are screwed up, but the data is still there. It is probably worth a shot.

rtg20 · 2008-07-24 01:42:01

thanks for the replies. I don't have a spare SATA HD. :-(

Maybe I will try ext2ifs on an XP machine.

So if i plug a USB hard drive into the USB port of the DNS will it just work...? I was mirroring RAID before so in principle I could set it up with one of those drives and try to recover the other one.

Is it possible to get teh DNS going without any hard drives in it at all...?

bq041 · 2008-07-24 01:42:58

I definately would not run it down flat. Yes, overcharging a battery is bad for it, but so is letting it sit around. I have personally burned out mother boards doing exactly this, as well as have several of my colegues. We found out after the fact that the manufacturer says not to for the reason above. I personally run mine on the battery at least once per week for an hour or two, but you want to charge it back up right away. I try not to take it below 20%, unless I absolutely have to. I'm going on 4 years with my current batteries.

That is a fallacy - it might have had a shred of truth back in the days of NiCd - Nickel Cadmium - battery technology, since that time we have seen NiMH - Nickel Metal Hydride - and all laptops in production for the past four or five years have used Li-ion - Lithium Ion.

It was not that the batteries wore out, but that the developed a "memory" of the usage pattern - if you used it repeatedly let's say 5~10% before recharging, it would remember that and not deliver more than 5~10% of it's capacity - battery memory was a very real problem with NiCds, less so with NiMH and can completely be ignored with Li-Ion.

My current laptop is in it's fourth year and still on the original battery with over 80% of it's capacity available - I'm predicting that the laptop gets replaced (some time next year) before the battery reaches the point where it becomes unusable.

well, Diskinternals finished its job...it found lots of files, but many of the sizes are wrong. any ideas...? thanks!

I am in a similar boat now... a lighting strike yesterday killed the NAS (DNS323) and I cant get it to do anything other than power up. I have it formatted Raid1. I ran out today and bought an external HD box for sata drives and pulled one of them out of the NAS and connected it to my desktop. I tried the EXT2IFS then, and it sees all the drives on my desktop except the New External. Is there a trick to get it to be seen ?

I had the NAS connected to the router before and now it wont even light up the port light in the new router... lik its dead. I tried switching cables too.

Is there another way to access the NAS directly, or another trick to try to get to my files too ? I dont want to lose all of this!!

Thanks for any help

You could try a Linux Live Boot CD like http://www.knoppix.com/
Reboot your PC with this CD and it becomes a (temporary) linux
system. This could give you access to your DNS-323 drive attached
via the external case.

Sounds like your DNS is broken, if it won't light up the port light.

I'm in the process of uploading all my photos to SmugMug, the SmugMug vault service supports raw files and it's really cheap. Fortunately I was able to get all (I think) of the photos I lost from a back-up I had at a former employer. I haven't been able to recover the data from my disk though, but I plan to try again later...I'm just trying all the tools mentioned in another, similar thread by oli.

EXT2IFS didn't work for me on XP or Vista.
