DNS-343 firmware version - 1.03 build 70
Hard drives - Seagate ST31500341AS
                  Seagate ST31000340AS

I am having a problem with the hard drive that is listed first, the 1.5tb Seagate.  Sometimes the folders listed in the drive are available, while most of the time they are not.  Each time I reset the DNS-343, the folders listed within the hard drive are available for a short time, then they are gone.  From the information that I have been able to gather from this forum and the fact that this problem does not exist with the other hard drive, I believe the problem to be with the hard drive itself.  Through this forum, I fund that there is a firmware update for the hard drive but when i go to the Seagate website, I learn that I already have the updated firmware version CCH1.  Additionally, my hard drive has the date code of 092501.  Does this sound like a hard drive failure or more of a problem with the DNS-343 reading the info from the 1.5tb HD?  As I am not the most competent person when it comes to networking, any thoughts would be helpful.

When you say "Sometimes the folders listed in the drive are available, while most of the time they are not." Are you referring to the entire Volume not showing or the folders with lets say Volume_1?

What do you see on the Status page for your drive info? Is it the same when you are able to see the folder as when you are not?

Another question would be, are you running your hard drives in RAID or standard?

[H2oSprayer]

Thanks for helping to try to solve my situation. 

First off, I am simply using the setup as a mass storage unit with no RAID configuration set.

Directly after resetting the unit I can see:  \\192.168.1.104\Volume_1 followed by all of the folders that are contained on volume one hard drive.

After the unit has been on for a few minutes I'll see \\192.168.1.104\Volume_1 with no visible folders to click on to open. 

After this occurs, if I refresh the admin page, the system info is the same but on the hard drive info page, the hard drive in slot 1 is missing and is only showing the drive in slot 2 with a normal status.

Well that would explain the missing data. It sounds like the hard disk is crashing. Is the DNS-343 OLED showing any warning signs when the hard drive disapears? Most likely either the power is failing on the hard disk or the disk is faulting some other way. Did you get these disks at he same time? I see the first disk only has about 1/3 of the power on hours as the 2nd disk.

[H2oSprayer]

The HD that is failing was purchased at the same time as the The DNS-343, in February of this year.  The HD that is running with out problems was purchased and installed in another computer prior to that.  The OLED is showing no warning signs of failure.  In fact, after the drive disappears, the OLED still shows that there are two HD's installed and the % of data on each HD.  I'm gathering that it is your opinion that it is a problem with the HD rather then the DNS-343?   As I am still within the warranty period of the HD, I should have no problem with getting it replaced.  Any idea if or how I can retrieve the data off the bad HD? 

Additionally, is there a way to set the DNS-343 up to allow for mass storage on two HD's while allowing the other two to be set to RAID 1?

I have four Seagate ST31500341A drives in a raid 5 array. I had many problems with the 343 dropping offline rather often. This made the whole unit unusable and unreliable. After much research and frustration I found that my drives just needed a bios update from Seagate. NO problems after I performed the update.

Since your HDD's are not RAID'ed (or RAID1), you can use a utility (ext2IFS ?) that you can use to mount the HDD and copy the contents via a pc.

HTH,

I have tried Raid5 and EXT3 with the 1.03 b70 firmware. it seems it still has the corruption issues. did a md5 check on the file . upload it on the nas and download it again to my system. the md5 checksum completely changes.

I even check the md5 physically on the nas iteself , it seems the file is already corrupted on the nas itself. Gosh, how come dlink is realising a bad product that corrupts data?

Have you tried your test on a totally separate system to eliminate the possibility of it being pc related?  I been using my DNS-343 for a while and the only time I encountered similar corruption was when I was testing Jumbo framing in my environment - compatibility issues with some of my devices prevents me from using Jumbo framing.

Can you tell me how to upate the BIOS of those drives?  Must I remove them from the DNS-343 to do so?
Is there any chance of losing the data on those drives when I do the BIOS update?
If there is a "how to" manual somewhere for updating the drives, I'd sure appreciate a link.

Seagate 1.5TB with firmware of CC1G and SD13-SD17 have a bug in them. You need to update to CC1H or SD1A. The bug only seems to occurs in RAID 5 configurations.

And yes you do risk loosing your data and you also risk making your HDD's a big paper weight.

The way I flashed my drives is to pull one out, flash it (Seagate provide instructions for this), put it back into the same slot.

Repeated for all the drives. When I turned my DNS-343 back on it didn't ask me to format, it just worked like normal.

Saying this, you might loose all your data following these instructions so make sure you back up your data.

Thanks, guys.  I really appreciate the leads and enjoyed reading the links you sent.
I'm going to hold off on updating drive firmware.  Here's why:

I set up my DNS-343 as an FTP server, and I can see the volume and all subdirectories and files.  I can read, write, and even rename files and create directories.  But only in the FTP protocol.  So I don't think my problem is with the individual drives or with the RAID-5 logical disk.

My problem is that I just cannot connect to that volume from any PC in my home.  I've tried everything I can think of, but am "turned down" at every attempt to map a drive.

This seems very similar to a problem that another poster on this formum had.  He finally tracked his down to Zone Alarm.  I don't have zone alarm.  And anyway, I turned off my antivirus and Windows Firewall to no avail.

Any ideas?  Has anybody else run into this problem?

tried singapore firmware v1.03 b60 . it doesnt have this corruption
