I have a DNS-323 that I have used for 3 or 4 years with no issues.  All of a sudden, when I select: Advanced - Network Access Settings and try to browse to a folder, it boots me out back to the login screen or just says:

The connection to the server was reset while the page was loading.
       
The site could be temporarily unavailable or too busy. Try again in a few moments.
 
If you are unable to load any pages, check your computer's network connection.

If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Any suggestions will be appreciated.

Thanks,

Mike

It does the same thing using IE too.

Sounds more like a network problem, rather than s DNS-323 network settings problem to me - can you access the unit normally?

Hi,

Perhaps there is a network issue but not sure.  On the weekend, I reset the unit and entered all settings again.  It was fine but now I have another issue.  On the status page it shows volume 1 and 2 as being present but when I use the easy setup tool to map to the volumes, volume 2 is gone?  I have no idea what's up.  The disk check tool on the NAS box shows both discs as being good.

I backed up all the data from both volumes to another drive on Friday so I may start by reformatting the drives and starting over from scratch.  Something very strange going on.

One thing I never noticed before is that the Network Settings page has a bullet selection for SMB that is selected automatically.  I don't remember this always being there but maybe I just didn't notice it before?

Thanks,

Mike

Just a FYI, I reformatted the drives, set up raid 1 and copied the files back to both volumes.

I now see and can MAP to both volumes as before.  FTP works again as this was failing too.

Very odd and cannot explain why everything went south but back up and running now:o)

The only change on my home network is a new windows 7 PC running 64 bit win 7 - first 64 bit comp I have had.  I don't think this would create any issues but that is the only change in months.

Something does not make sense in your last post.

The only way you will get two volumes with RAID 1 is if your disks are different sizes, then the RAID array will take the size of the smallest disk.  The remaining space on the larger disk can then be formatted as a standard volume.

With a RAID 1 array you only copy files to Volume_1, the internal nas system makes sure they are copied to both drives and does not differentiate between disks in the array.  Therefore mapping both drives is a nonsense and may well cause problems because the system can not keep up with any changes, beside which, both drives should be identical.

If you do indeed have a RAID 1 array setup then you should only be looking at Volume_1 and NOT be accessing the disks individually.  It is also why you can only see one volume in the easy setup tool - as far as the outside world is concerned there is only one volume with RAID 1.

Maybe I am not clearly explaining.  Ever since purchasing the NAS I have had 2 x 320gb drives in it.  I selected Raid 1 and it asks how large I want the Raid 1 section to be - I chose 100gb.  Volume Name: Volume_1, Volume Type: Raid 1 now shows as 98290 and the balance is Volume Name: Volume_2, Volume Type: JBOD now shows as 431413.

I have always used it like this with 2 volumes for 3 or 4 years?  Never had any issues at all.

The way you have setup your drives is like the first possibility I mentioned except you chose to have a small RAID 1 array.

In theory you shouldn't have any problem with that setup until one of the disks starts to develop problems and uses up its store of spare sectors, then the problems begin.

The fact that you reformatted the drives would clear up some bad sector problems as proved by the fact everything is working again.  The one thing you need to do is to run the SMART test for each drive to check their physical status.

OK thanks for the info Ivan.  I see an open source one called CrystalDiskInfo.  Not sure if there is a particular one you would recommend but any suggestions will be appreciated,

Mike

Here, in the usual run of testing clients equipment, we use the disk manufacturers disk test tools. 

Our normal procedure is to take a drive, having marked which slot it is from, and put it into a hot swap tray that has been modified as a USB/SATA adapter, and run the disk tools on it there. 

Most drive manufacturers disk tools allow running SMART tests as well as others for checking questionable sectors. 

The main advantage we have of doing it the way we do is that we get log files for each drive which give a history of that drive and allow us to flag potential problems and warn the clients to be more diligent with backups. 

As an aside we run the tests on new drives before they are put into service which has in the past saved us problems - not passing SMART tests means a returned drive for replacement, although either the quality of drives has improved or our supplier is doing some checking before sending them to us

Thanks for the help

Hi Ivan,

I pulled apart a WD My Book drive so I could use the guts to attach other drives and I ran the tests on the 2 drives from the NAS.  Both returned as good so they look OK and all seems to be back up and running now.

I also have additional 'other drive' backups of all the data just in case.

I appreciate the help with the procedure for testing the disks, this will probably come in handy to test other drives in the future.

Thanks,

Mike

Glad to have been of help.  I like your ingenuity in getting the where with all to test the drives    What we use started life as the internals of a no name external drive case that was added to an IcyBox mobile rack so that we can use the key to turn it on.

The main thing is you don't have to worry about the drives now
