Title: Missing Volume_1
Post by: df78 on August 04, 2013, 11:56:10 PM
Hi all,

This morning, my DNS343 is not recognising my Volume_1. This happened after I forced shutdown. I can get to the admin page but I cannot see any hard drive. Hard drive information is missing under the status page. I can run the SMART test but I cannot run scan disk as no volume is shown.

Is there anyway I can recover this Volume_1? Please advise, thanks.

Does your volume consist of a single HDD as a Standard Volume or multiple HDDs in RAID (What RAID)?

Standard volume. 1 disk, 2 tb only.

You can try powering down the unit and checking to make sure the HDD is properly seated in slot #1. Is the HDD spinning up when you start the DNS-343? If you remove the front face of the DNS-343, you should be able to easily feel the HDD to determine if it's spinning.

If all else fails, the following sticky thread outlines data recovery options: DNS-343 - Data Recovery (Windows PCs) (http://forums.dlink.com/index.php?topic=41302.0)

i don't think the hard drive is spinning in slot 1. do you think i should put in slot 2? i used funplug previously, will that matter?

I can't speak to the consequences of using FF.
Did you try removing the HDD from Slot-1 and re-seating in Slot-1?
You can certainly try Slot-2 to see if there's something wrong with the DNS-343.

Coincidentally, here is a sticky post on our FAQ that I just put up yesterday: ShareCenter - Troubleshooting a Bad HDD (http://forums.dlink.com/index.php?topic=55055.0)

thanks. understand that it will format the hard drives. will that be done automatically?

What will format the HDDs?

dns343?

If I plug in the hard drive from slot 1 to slot 2, will the data be formatted automatically given I have funplug installed?

If you move the HDD from Slot-1 to Slot-2 (for testing purposes) the HDD configuration and data should not be impacted. However, I cannot comment on any impacts FF may have on this process.

Alternatively, do you have a spare HDD you can place in Slot-1 just to see if the slot is working and provides power to the HDD?  :-\

moved slots but the nas detected the hard drive but not the volume. unplugged and installed linux drivers and my files seemed to be intact. Is there anyway I can repair it so that it get seen by the nas?

The good thing is that your data is still intact and your hardware (DNS-343 + physical HDD) is still working. If the DNS-343 is not detecting the volume as damaged, then there's no way (that I know of) that will enable the DNS-343 to make repairs internally. I am not privy to any third party software that could repair the volume such that would make the HDD visible to the DNS-343. . . try searching the forum though, as users have tried such manipulations over the years (you may find something).

How much data is on the HDD? You may find it easiest (and perhaps your only solution) to reformat the HDD in the DNS-343 and copy the data over from a backup.

a lot of data... 1.6gb

I presume you mean "TB" (not "gb"). When it comes to data integrity, it's usually best to take the safe/proven route and copy the data to a freshly formatted HDD rather than an unsupported ad hoc solution that may cause issues down the road.

as expected, some files have data integrity issues. i am using paragon extfs windows viewer. will that be the reason?

I would think that corrupt files are a symptom, but not the root cause. If the volume itself has some level of corruption (at the filesystem level), then it's very possible that the DNS-343 may not recognize the HDD as valid. It follows that if the volume itself has some level of corruption that files on the volume may also be corrupt.

Rather than recovering the data on this volume, do you have a backup to restore from?

have a very old backup two months back.

Since it appears there is some bad data on the HDD, the only recourse I can see is recovering the files you know to have changed since your last backup, performing a fresh format of the HDD, and copying your data over. You may also want to schedule a recurring backup from your master data to your backup.

Do you have only one HDD installed in the DNS-343? You may want to consider adding another HDD and scheduling a recurring backup between your source HDD and the second HDD for a local backup. You can also schedule or perform less frequent backups to a third party device for an additional layer of security.
