I recently deleted some files from a D-Link NAS DNS-323. It's a dual drive NAS and it was set up in a RAID 1 setup.

Since all the 'undelete' utilities I tried to use are unable to detect mounted NAS drives, I decided to try and connect the disk drive through a SATA->USB2 external enclosure.

Unfortunately, this is not working as planned either. While the disk shows up in the device manager (listed as 'ST332062 0AS USB Device'), it does not have a drive letter assigned, nor does it show up under 'My Computer'.

I have three questions:

1) Is there a utility that can undelete files directly from a NAS?

2) Can I read a hard drive that is formatted by the D-Link NAS DNS-323 in an external enclosure or does this format prevent it from being detected as a normal external drive.

3) Is there any other was I could recover the files.

The files I deleted are pictures that I just recently added to the NAS, so they were not backed up yet.

Thanks for your help.

PS: I am running Windows XP.

I can answer questions 2 and 3.

I had this same problem only a few weeks ago with my DNS-323.

I removed the two drives from my DNS-323 and plugged one into an external box, which was attached to a desktop running Windows XP SP3. [the drives were mirrored (RAID 1), so the contents on each drive was the same].

I installed a nifty little freeware onto the desktop called "Linux_Reader", by DiskInternals. It reads the EXT2/3 formatted NAS drives and displays the contents in your windows folders.....just as if it was an NTFS drive. You can then cut/copy/move files from your NAS drives to a drive on your desktop.

The freeware can be downloaded form here:

I can't remember the exact steps I used to configure the software, but it was very easy (and i'm not very IT savvy).

Cheers,
Ian.

Thank you very much, Ian. I ended up purchasing the DiskInternals Uneraser, which solved both the mounting of the RAID 1 drive and the recovery of the files in one fell swoop. Worth the $39.95!

Can you provide more details of your experience. I have the exact same problem and purchased DiskInternals Uneraser and connected 1 of the drives to my pc directly through a usb to sata cable.
The program detects it and it lists the folders at the root but when I double click it does not show any files. Can you help?

Same equipment, different situation. I had 750 Gb hard drives in my DNS-323 and wanted to move to 1 Tb drives (mirrored). D-LInk said I had to remove the 750's, install the 1000's, then use a utility that would read Linux EXT under Windows (they didn't point me to a product) and copy the 750 from Windows to the 323.

I had the same problem, and the folder that was empty basically had all my downloaded files for the last couple of years! Anyway, I downloaded EXT2 IFS from http://www.fs-driver.org/. You have to have the drive connected before you install this driver (if there's another way to do it, I didn't see it). During installation it asks you to assign drive letters. Once you've done that, you can see the folder contents in Windows Explorer ... but you're not done yet! (BTW, SysInternal's free viewer saw the folder but, just like their Uneraser, indicated it was empty.)

So after this I was able to view all those missing files in Windows Explorer, but when I tried to copy them it indicated there was no data. So I used another utility - Ztree for Windows - and it was able to copy the data to the new drives. I hope this helps.

Thank you for the input. Unfortunately I ended up loosing that info (and spending the $40) this time around but I will keep this info handy should it ever happen again. Thanks again.

Ssd raid 0 poor benchmarks
By sub mesa, 9 hours ago:

Expensive hardware RAID for a simple RAID0 array? LOL! Dont waste your money please. Even the most expensive hardware RAID are slower than software RAID when it comes to random IOps benchmarks; Areca ARC-12xx seems limited to 70.000 IOps. There can be several reasons your RAID0 is not functioning properly: - you have a 'bad' partition (misaligned) starting at 31.5KiB offset - you have multiple partitions on the RAID; and the second partition is not properly aligned - the selected stripesize is too low (< 128KiB) - you defragmented your SSD at least once during its lifetime (you need a full zero write to regain performance) - you performed inadequate benchmarking (low queue depth) If you want some serious advice and really solve this issue, you must do some work yourself: - explain your setup in more detail (enabled the 'write caching' option in Intel drivers? How did you create the partitions? Can you check for the partition offset, etc) - post proper benchmarks performed at the filesystem level, for example HDTune Pro's "File" benchmark. The normal HDTune benchmark only tests raw disk access; without using read-ahead which your filesystem does use to allow parallel I/O processing. If you can do that, i might be able to help you out with some specific advice.
