Ok so I bought this DNS-323 because I looked at all the ones in Fry's and this one seemed the best they had.

I also bought 2 Samsung HD103UJ 1TB drives.

I have been using it for about 3 months with Raid (mirroring) setup.

The last couple days everyone has been complaining it's slow and taking forever for files to load, copy, and the music on itunes has been stopping starting.

So I decided to take a look.  When I logged in the NAS said the Raid was degraded and when I tried to do a disc scan it said it failed.  So I shut it down and restarted it.  Same problem.  So I shut it down and took the right hard drive out and restarted it.  Still same problem.  I can see all my folders and files but everything is very slow when trying to open a 5mb photo or even if I try copying the files to my desktop hard drive it takes forever for 1 5mb file. (I know it's not my network cause copying a file to my wife's computer over gigabit is super fast).

So I told the raid to rebuild and it finished and the device is still acting the same way.  I'm about ready to take one of the hard drives out, download EX2IFS and put the drive in my desktop and get all my data off of it before something major happens and I lose all my wife's photography for her clients.  That would not be good. We do have some of it backed up elsewhere but I figured with mirroring it's not very easy to loose anything. 

Anyone have any ideas for what is going on?

Tonight i even upgraded to the new Firmware 1.09 just to see what would happen.  I really need to get these files safe but copying at 13KB/sec (not MB/sec) is very slow.

Thanks

BACKUP FIRST!

After you have everything backed up, then start fooling around.  RAID of any level is NOT backup, which you are in the process of discovering.  Don't make your discovery process any more painful than it is!

Can you copy the information faster by using FTP? 


Do you have your important files stored elsewhere as well?  If you only have them on the NAS and using RAID1 it is not a backup solution.  As many people here will tell you, RAID1 is for hardware redundancy, not backup.

Wiggs,

How am I supposed to back up when I can't really?

I know raid 1 isn't a backup and I have been meaning to get another external hard drive and backup but I wanted to see how well this nas would work first.

Why can't you really backup?

Why can't you really backup?

Well I can backup if I want to wait for many days while it tries to copy all the files even if it can complete. There is 250gb of data.

Like for example if I go to my \\mediaserver\pictures on my windows computer I can see all the folders and all the files but just to copy one 5mb photo to my desktop it takes about 5 min.

So what is the best way to back it up.  I brought one of the 2 hard drives to work and was going to plug it into a SATA external case and hook it up to my computer and try and back it up but I can't find a SATA external case.

Well, I sure wouldn't screw around with it anymore until I did have a good backup of the data!

Well there is a possibility that the drive is dying.  Samsung's disk
diagnostics utility will help you determine the health of the drives.
Still, you would want a backup before you run the diagnostics.

Both drives are probably not dying at the same time.

Ok so here's what I have done now.  I went to Radio Shack and bought a SATA USB HD enclosure and put the drive in that.  Plugged it into my windows computer, then I ran Ext2IFS and put a drive letter on it. Went to the drive letter and everything is there.  So what I'm doing right now is copying all the data to my other NAS which is a Buffalo (Single drive).  Then after that I think I'm going to have Samsung replace both drives and then sell them and get a different brand.  I have read a lot of reviews that were saying those Samsung drives were known for failure. I hope it's just the drives and I can get new ones and put them into this Dlink NAS and keep using it.  Also I think I'll buy another external hard drive and backup the data on there as well.  Wondering what's the best way of doing that.  Does the Dlink DNS-323 allow you to hook up an external drive to the back of it and tell it to back up to it?  I know my buffalo does that.

Thanks for all your help guys. I feel a bit better now knowing the data is getting copied off and it's not lost.
