NAS reset on a D-Link DNS-323

This case has a number of important things to learn.

The PC that usually access DNS-323 crashed and I have to replace it. However, with the new PC, I’m not able to detect DNS-323 using using the Easy Search utility. Thinking that the config of DNS-323 is corrupted, I reset the unit with the reset button.

Still unable to find DNS-323 on Easy Search, so access it using IP address and got a shock. My personal files are gone. Only those that I share publicly are visible. Conncet the HDD to PC using SATA-USB and tried reading the disk using R-Studio but it looks the same as reading it thru the DNS-323.

Can anyone advise how can I recover my files

First of all, if the system was not affected by the failure, it does not need repairs. It was the PC that failed, not the NAS. The NAS was in all likelihood fine before reset. The trick to figure out what is the IP address of the NAS and then access it by IP should have worked without reset.

Finding the right IP is sometimes tricky. Obvious steps are to look at the router DHCP assignments table, which lists IP addresses given out by the router, if the network is using dynamic IPs, or you can go as far as a ping/port scan if addresses are static and you do not keep track of addresses. In case of static IPs, the best place to write down the IP for the NAS is on the NAS itself.

You can try Home NAS Recovery to see if it finds missing files (if the undelete is better than that in R-Studio, this might work), but if not, the data is lost. EXT filesystem does not go easy on deleted files.


Undelete from a NAS requires locally attached disk

This is a recurring question indeed – Can I recover deleted files from a MyBookLive drive?

I have a 1TB My Book Live network storage drive and I accidentally deleted one of the folders that contained some video files I saved. …  lots of programs out there that claim to be able to recover the data … have been unable to access the drive.   I did map the MyBookLive drive as a logical drive to my computer and can see it there.

Seeing a NAS as a drive letter, E: or something, in My Computer is not good enough. The network-based connection protocols are only good for file-based access, that is, give me this or that file, or store such-and-such file. To undelete, one needs sector-by-sector access, that is, read me the filesystem block 0, 1, 123, whatever. So, some fumbling with a screwdriver is in order – remove the disk from the NAS, or the entire set of the disks if multi-disk, and connect them to the PC whichever way you prefer. After which, undelete software will work.

Data recovery for Terastation

This case has a common mistake of calling Terastation with two Rs. The correct variant is with a single R, derived obviously from Tera- as in Terabyte.

I just [mistakenly deleted] 700GB on a Networked RAID drive (A buffallo Terrasation)

Does ANYONE have a suggestion as to what Data Recovery software/undelete software I can use to undelete software over the network off a 700gig RAID array?

The only thing I have seen so far is Active UNDELETE Enterprise 5 (enterprise version supposedly can do network and raid …)

Actually, I have. Home NAS Recovery ( is quite good in undelete on Buffalo NAS.

Nothing works over the network, though. Active Undelete works with RAID, sort of, if you know the parameters for the RAID. Home NAS Recovery, on the other hand, is fully automated.

Network Recycle Bin and undelete

This specific question is about IX4-300d, but it applies to virtually any NAS out there.

The question is about some Recycle Bin equivalent for a NAS.

As in most NAS (if not all) when a file is deleted from a share in IX4-300d it disaappear “completely” from the drive. No chances to recover it from a Recycle bin. I read in a post that UNDELETE by Diskeeper might be a solution creating a “virtual” recycle bin. I decided to try it and downloaded a trail version of the program. But it did not recognized the drive/shares in the NAS. Does anyone has any experience with UNDELETE in NAS?

First of all, some NAS vendors provide an equivalent of the Windows Recycle Bin. QNAP, for example, calls this feature Network Recycle Bin. It keeps files retrievable as best practically possible (subject to age and free space constraints).

Whatever delete protection mechanisms, they must be implemented and run on the NAS side, because it is the NAS filesystem that owns the files and performs deletions. Any Windows-based installable recycle bin software only works with locally attached disks.

After the files are deleted with no Recycle Bin in place, there is still a chance – our Home NAS Recovery can help (with varying success depending on how long since the deletion).

Recuva and remote undelete

This conversation happens on Piriform’s forum,

I have deleted a file on a network Buffalo drive. I am using the free version of Recuva. I can navigate ok to the folder but the OK Button stays greyed out.


I believe recuva works only on local physical drives


Does the business edition of recova only work on local drives also?

Any version of any commercially available data recovery software requires the drive to be removed from the NAS. The definition of local physical drive may vary slightly, but certainly a drive still in a working NAS isn’t one of them.


Can I undelete a file on NAS drive?

The evergreen theme of undelete over the network comes up again on 7forums,

…D-Link 323 2 bay NAS drive…

I accidentally deleted a couple of files … are there any utilities to allow me to undelete.

I tried a couple of Undelete programs I have – but they don’t see networked drives.

And the answer is again you can undelete, but not over the network. You need local access to the disks. With two bays, this should be rather straightforward, no fancy hardware required. We have this covered in our FAQ, and it applies to any NAS, by any vendor.

Recovery over network

The original question goes like this (source)

I have [whatever setup with] mapped network drives in the form: \\nas\pictures, \\nas\music, etc.

… accidentally deleted a folder ..

I am looking for a piece of software that allows me to scan network drives for deleted content and possibly recover it. Most everything I find is to install on a file server. In my case a file server doesnt exist for me to install a piece of software on.

and the short answer is, you can’t have that.

The longer answer is (already in our FAQ) that even if you want a couple of files undeleted, you still need a full-scale analysis with full-scale hardware setup, removing disks from the NAS, putting them into a PC, and so on. The PC is not required to be some kind of a file server, any modern Windows desktop will do. If you do not have one, you have to get it. This applies to any NAS you can have, in any configuration.

Theoretically, as NAS runs Linux, you can login into Linux, install some Linux-based undelete software, and run it inside the NAS. In the end of this process, though, most people wish they’d have gone with Windows and hardware setup route.
