Ok.  I think I got it.  I used the D-Link Storage Utility on disc.  I can now view the DNS from the main comp.

Now.  To get this thing backed up.

So it's possible that the degrading didn't just happen due to a drive failing right?  That it could have been other issues?  I'm going to test the plug but what readings should I get off of it (from North America btw).

Glad you go the Asus router going with the DNS.  ;)

So am I.  Not sure why a tech company like Asus has such clueless people working their support lines.  That whole experience was bizarre (and I spoke to 3 different people).

Any thoughts or comments to my post above your's?

There are several things that can cause a RAID array to become degraded and most of them are not things people think about.

Just to be on the safe side run the full SMART test from the NAS WebUI on both drives and have it email you the results because it can take a long time with large drives.

If both pass the test then it is usually something external that caused a bad write to disk.  This can be something like a power fluctuation during a disk write or a laptop going into hibernation without fully flushing the disk cache.  We have seen both with the power fluctuation being the more common.

I think some support expects users to be using there set default IP address and forget about the fact that it can be changed, thus they only think about the default addresses in there troubleshooting. I think ASUS, Netgear and Linksys are the ones that use .1.1 where D-Link and to sure of any others, use .0.1.  ::)

Ok I started a Extended SMART test and asked for it to email the results to me.  It seemed to hang at 10% wouldn't go past, and didn't want to allow me to stop the test.  Managed to abort the test and then did a quick test.  Both results had the drives passing.  I'm going to try an extended one again and see what happens.

Ok so it seems to be "stuck" on 30%.  Lights on the front for the hard drives aren't blinking at all.  Don't know if that's normal or not.  I am doing the SMART test on both drives at the same time.  Should I have only done one at a time?

When I said 'a long time' I mean just that a long time - something like 12 hours plus.  We did a full SMART test on a clients 4 TB drive and it took 26 hours and that was using the disk manufacturers tools SMART test.

Ok.  You're right.  It did in fact take a long time.  Thankfully not 26 hours though.  It did complete some time over night though and I got emails saying both drives Passed.

So next step...back it up?

I'm guessing I pull the drive with the most data, plug it into my USB dock, then transfer the data that can not be replaced (photos, home movies) to an external usb drive.  That's how I'd go about it.  Any suggestions otherwise?

Yes, that will work.  In fact it is one of the advised ways of recovering when a unit goes down and the disks were formatted as RAID 1.

Just one caution.  Don't let windows write to the disk because if you do things can get very messy.  Here we have a computer with 5 removable disk trays (2 IDE and 3 SATA) that runs a very slimmed down Linux OS for use in such situations.
