I purchased a DLINK DNS 323 about a week ago.
Model: DNS-323
P/N: ENS323M_B1G
S/N: P1KB192001751
H/W Ver: B1
F/W Ver: 1.06

I bought two Seagate ST31500341AS 1.5TB drives, serial numbers 9VS1B6XG and 9VS1LHYM,
firmware CC1H that I installed in a raid 1 configuration.
The DNS-323 came with firmware 1.06 installed.

My network is a wired 100Mb/s with cat 5e wiring. The plan was to upgrade my Dlink DES1005D
switch to a gigabit switch once I had tried out the DNS 323. The network also has a Dlink
DI-604 router and an Edimax wireless access point.

Things started well to start with. Drives formated ok. I copied across quite a lot of data
from a Windows Vista (32 bit) machine using standard copy and paste. Speed seemed to be
reasonable. Something like 30GB of data took 1hr 40 min to copy.

I also added some users and a group. All of the access permissions seemed to work fine.

However, things then started to go wrong.

The DNS 323 became very unresponsive. It will take longer to browse into directories, say
10 seconds or more, (with the Windows Vista address bar refreshing with a green "wave" from
left to right) and then to open a jpg file 2MB in size would take several minutes.

I got similar behaviour from a Windows XP machine. After doing various reboots of of the
all the bits on my network no improvement could be made.

I then saved the settings I had created and restored the box to factory defaults. This has
all of the servers etc disabled and removed all of my users and group settings. The data
was still on the drive and could now be accessed from the Windows Vista machine without
having to enter a username and password.

However, it is still so slow as to be unusable when browsing and tring to access small (say
2MB) files. I also often get a "Not Responding" message in the Windows Vista Explorer
window for up to a minute or so. It does eventually come back if left.

When I now right hand click on a 2MB jpeg file and try to copy it I get in a pop-up window
the error "Could not find this item ...". Even though I can see the file in the window.

I found on a forum a reference to the NAS 323 and the Seagate drives I have:

I have checked on the the Seagate page:
http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=207931
and the utility states for each of my two drives that my "Drive is not affected. No action required".

Other references have been made to issues with the DNS-323 and the same Seagate drives:

Anyone any suggestions?

Seagate has recently had issues with their very large 7200.11 drives. Firmware and manufacturing issues.  That could very well be an issue for you independent of the DNS-323.  You should make sure your drives are solid before thinking the DNS may be the issue.

As far as the DNS-323... Dlink can weigh in on whether the firmware will support the 1.5 TB capacity drives in a Raid-1 configuration.  The verdict may still be out on that.  I have read that others have used the 1.5 Gig drives fine as separate disks in the DNS-323 (not RAID-1, though). 

I have a pair of Western Ditital 1 TB Caviar Black in RAID-1 and the DNS has worked fine in this config.  I started out with Seagate 7200.11 1 TB drives and gave up since every Seagate I tried suffered with firmware and/or reliability issues.  I RMA'ed all of them and swithced to WD disks.

Once I got the WD disks, I did a lot of diagnostics and read/write testing on them in a standard PC before moving them to the DNS-323.  Then after building the RAID on the DNS, I did a LOT of testing to make sure I saw no issues before storing any "live" data on the DNS.

Thanks for the reply. Reading the Dlink site before purchase 1.5TB disks did appear to be supported. It is mentioned in specifically in firmware 1.06 I believe.

I have emailed dlink support and I am awaiting a response.

If it is an issue with raid1 and the drives, is there a recommended way to convert back to single drive, ie drop raid 1 support? I could reformat both drives and then re-copy the data, but it might be nice to try it without doing that first.

On the device web page the status says that my disk are in sync and I can see not report of any other issues.

My plan was to see if anyone had any ideas, wait for Dlink to respond and then decide what to do next.

I also have a DNS-323 with 2 1.5TB drives with the same firmware and do not see this issue.

i have been using the 3232 and the same hard drives since the beginning of January with no issues

Thank-you for the replies. It was useful to know others have the same, or very similar configuration working ok.

Dlink technical support have quickly got back to me with some suggestions.

I can now confirm that the issue is not with the DNS-323 or the Seagate ST31500341AS 1.5TB Drives.
On a 100Mb/sec lan I able now able to get transfers from the DNS-323 to a Windows Vista machine that max out the lan (100% in the Vista network traffic monitor), at around 11MB/sec. This was transferring a 700MB CD iso image whilst at the same time reading and playing an mp3 file from the DNS-323, which did not stutter. This was with both devices connected to my Dlink DES1005D switch.

However, if I connect one or both devices to a lan port(s) on my Dlink DI-604 router, the transfer speed drops to around 32KB/sec or about 2.5% network utilization, and I get stuttering mp3 playback.

I would suggest a similar approach of moving the connections around, trying different cables etc, to anyone reading this thread who has similar issues. Another experiment, which I did not need to try, would be to connect the DNS-323 directly to another computer using a cross-over cable (having already established a suitable IP address on each device).

I designed my home LAN around a Netgear GS108 Gigabit switch. Router, PC's, DNS-323, Wireless access point, printers - all connected to the switch. I do not rely on the LAN ports on my router or other devices for anything that needs high-speed data transfer.  The GS108 has LED's for each port that indicate both the speed and duplex each port is running at. Thus I can verify that every port/device is synced with the switch properly.

did you install the vista drivers...i had a problem with mapping on reboot untill i installed the vista drivers. Perhaps your issue is similar.
