Hello,
we tried to reset a DX4000 which originally had 4 drives with 4TB.
Because we do not need so much space on the NAS we removed one of
the drives just using 3 of them. (One in reserve in case of trouble in the future )
We followed exactly the description in the manual and
everything seemed to work fine …
But now we have the message “Initialzing OK Searching …” on the display
of the DX4000 for several days!! and nothing seems to happen.
Could it be that the removed drive makes trouble (initializing with 3x4TB instead of 4x4TB)?
Or in other words is it possible at all to intialize a 4x4TB DX4000 as 3x4TB?
Does anybody succeed in doing this?
I know that a DX4000 works with 3 drives, we have another one which was
originally delivered with 2x2TB which we expanded with a 3rd drive, by
just adding a 2TB drive ‘on the run’ and it worked perfect …
But maybe a DX4000 4x4TB is somehow different to a DX4000 2x2TB
and requires that all 4 drives are present on initializing?
But I think what may happen is if it does boot it is going to complain about the missing drive. If you still have the thumb drive used in the middle step look in the wd folder for a log file. At the end look and see if you can tell if it is trying to do raid 5 with the 4 original drives.
If it is all you need to do is clean all 4 drives with diskpart, then stick 3 in the box and start over with the middle step. The drives do not forget how they were configured. It took me over 3 months to figure this out. I had 2 drives like your other box and stuck a 3rd in just to see it work, Then I tried over and over to go back to 2 drives. It would go about 5 days and then say fail
That is kinda what I was expecting.
So if you have the time and are just curious you can wait and see what happens. But if it boots it is going to complain of the missing disc all the time and I am not real sure if it would run on 2 disc’s if one failed. Maybe, maybe not.
So I think you are going to have to do it again, cleaning the raid profiles from the disc(s) for it to be right. Either go ahead and abort or wait and see what happens.
“I:” is obviously the partition for the Windows system,
“Basic data partition” is the ‘real’ data partition as I guess
and “G:” is the problem, as I think, because it ‘simulates’ the complete raid
which can only have 10.86 TB if 4 drives are present - 3 drives should have much less …
Just another note:
*I had tried to add some screenshots but my (last) post was hidden (flagged by the community) *
*because of that … *
*So no pictures of my investigations - sorry!! *
After cleaning the disks we had (the usual) “Bad Storage” on the LCD
After “recreate my storage” this was fixed
(see: It show me "Bad Storage" in LCD )
Now we are in Recovery mode (since nearly 2 days ) - LCD shoes “Recovery Started” …
No, we didn’t, we are a little bit unsure when/if we may remove the USB-Stick,
So we started the recovery and did not touch the box (and the stick of course) …

I would say it looks fine with member discs 3 at the end. The other said 4 member discs and the MB’s is lower.
I was worried you might have to do 2 drives then add the 3 since I don’t think they ever ship a box with just 3 drives they may not have planned that option.
I would say let it roll and see what happens.
