Maybe it is the hdds. you said they were WD red but you didn't specify if it was on the approved hdd list. When i did my raid setup, i bought two seagate hdds. I installed one, moved my data over, and then I waited for a few days then installed the 2nd hdd. didn't really have a problem. i don't remember how long it took to setup raid as i went out of town for a few days. when i came back it was done.

I don't think so. There is something sh***y in the realm of Dlink new enclosures. I got 2 WD20EFRX (WD red 2tb) and it is in the approved list. Yet when I tried to add them in raid1, I got stuck at 58%. I know what I'm doing, I've been doing IT support and system admin for more than 10 years. I got some other Dlink here (DNS 323 and another DNS-325 - in raid too but with 1tb disks). From that info I would say it's probably linked to some specific hard drives models (worked with my WD black 1tb disks with the exact same enclosure).

I tried going through the web interface with chrome, internet explorer, mozilla firefox and I get the same problem each time. Stuck at 58%. So it is not linked to the setup program.

It seems it's possible to get around the problem but by doing things that we should not be doing (see gorsey's post). I'm gonna try that, but it really doesn't fill me with confidence about the restoration of a failed disk. I mean maybe there will be a bug when I try to get it to work again. Well I really hope that this bug does not effect raid restoration.



EDIT :
Well I got it setup. So the drive I got from WD had some partitions on it. It was never used before and it's coming straight from the shop. I had 2 partitions of around 500 mb. I deleted those partitions and got a new one setup with everything available in it. I didn't format the disk. I then put those disks in the DNS-325 and it worked without a problem.
I don't think this will be a problem for a restore if one of my drive fails. Well I might need to do the same, delete partitions and then create a new one, but after that I think I'll be able to restore the disk.

Still it is really stupid that a NAS enclosure cannot delete partitions and recreate what it needs. Maybe it should ask about it, but it should be able to do it.

It appears that you have found one of the problems with WD disks.  It is the reason every disk we use is given a full range of tests before it is installed into any equipment (we have had a supposed 'new' disk that had a load of personal data on it).

As to restore if you have a defective drive, check that the new drive has either no or one partition before installing it and you should not have any problems.

Regarding your last point.  These NAS boxes are for general purpose use by everyone, if the firmware did what you would like then I think we would be seeing a lot of people on here with bigger problems of lost data because they clicked OK without reading and understanding what was there.  Yes, it can be done and is on such things as an HP storage array but then such storage array is looked after by an experienced admin, not a member of the general public.
