Guys,
I am a new to this forum and sorry if this problem have been asked before in this forum. I have searched the forum but look like my problem is unique and have slight difference with other problem posted here, so I post as a new topic. Please help.
I got the unit with 500gb installed (no RAID installed). Firmware recently upgraded to v1.09
I thought upgrading the firmware can solve the problem but it wasn't. (Same problem also happened with all firmware start from v1.04)
I got 2 boxes connect to the unit, Windows 7 and Windows XP.
Both of them can access to the unit without any problem. However, most of the files are missing but folders are there.
Last week, it was happened but I can resolve it by turn off and on the unit. But I have no luck today.
I believe my files are still there since I can see them without any issue after I reboot it last week.
What caused it and your suggestion to fix the problem permanently?
Thanks

The only cause for this that I can think of is a failing or corrupt disk. Folders wouldn't disappear since they don't really exist other than in the allocation table.
Have you run the manufacturers diagnostic utility on the drive?
Any pattern as to when the files "disappear"?
Does the drive have S.M.A.R.T. capabilities?

Thanks FunFlier, sound logical.
Tried to answer your questions
The diagnostic utility that I can run is only "Scan Disk" provided by the vendor (via Tools, Disk Tools) and the result was failed.
The pattern was like this (new findings)
1. Start from cold boot, I have 10 folders on the root and I can see all of them.
9 Folders are ok, I can see the files inside their folder
There was 1 folder that I go inside that have no files at all and no files under sub folders as well.
2. After I go deep inside to this folder, all the files in 9 folders dissappeared (they were fine initially)
I repeat this procedure and looks like I can get consistent pattern.
I guess my hard drive (Barracuda 7200.11 SATA 3Gb/s 500-GB Hard Drive) should have S.M.A.R.T capabilities?
But how to confirm? Can it recover the files? Appreciate if you can deliberate more.
If the hard drive failure is the answer, what is the best strategy to recover?
Does take out the hard drive from DNS-323 and put into my Windows box is a viable solution ?
I understand that the file system are different between this unit. Can my Win XP or Win 7 read that? What the driver need to load?
Thanks, hope this issue can resolved soon. Appreaciate for any help/pointers from you.

I agree that the disk drive is probably bad, especially since your "Scan Disk" failed. It looks like that it degrades over time after a cold start. Might be heating up or is faulty otherwise.
If it is failing in the DNS-323, you won't be able to install a fun_plug to try to run smart tools on it.
So, I'd probably plug it in one of your PC's and find some sort of testing utility to see what's up. The disk is formatted with a Linux file system, but you can probably still run a low level test without reformatting it. You may have to go to a Seagate website to get such a utility.
It doesn't sound like you'll be able to save the files on it. One thing you might try is putting the disk in a freezer overnight and then put it back in the DNS-323. It might stay up long enough to pull the files off, but I'd still be doubtful of the result. I never tried doing this, but there are more than a few reports of this being helpful. I can't see the harm in trying.
If you have an other known good disk, then I'd try putting that in the DNS-323 and see if it works, to try to rule out the DNS-323 being bad.
But it sounds like the disk.

I would not recomment the freezer part, but agree otherwise. Cool perhaps, but not frozen.
After running the manufacturers diagnostics, you may be able to recover some files, maybe not all. Only one way to find out.
The is a windows driver to load and read the linux partition. Lots of existing posts on that option.
