ReadyNAS Duo RND2000 several questions of not starting up, Raid0 and removing one disc....
Hi! My NAS stopped working earlier this week... shutted it down sinsw it made a whining sound and now it wont start... It makes a clicking sound on startup (like reader arm moving) from one o...
Looks like someone edited the duplicate posts from the thread - also deleting your followup questions. I was typing my response, but a side effect of the editting was to destroy my followup before I finished it. So I don't have your original questions handy.
What I remember is you asking again about testing the NAS with only 1 drive inserted.
Both JennC and I recommended against doing that. It risks doing more damage to your data volume.
However, our replies both assumed that you got the RAID-0 mode right in your initial post. If you were actually running RAID-1 or even RAID-0 with two volumes (also called jbod) our replies would have been different. So please do tell us if you are certain about the RAID-0 with a single volume configuration.
You could power down the NAS and remove both drives (labeling by slot). Then power it up to confirm that the clicking noise is gone.
Another option is to get two new drives, and set up the NAS from scratch - setting aside the existing two drives (labeled by slot) for possible future data reccovery. If you do that, I suggest WD20EFRX drives.
it is/was in raid-0 with 2 discs..one 1TB and one 1,5TB.....
...but what ive heard is that Raid-0 needs both discs since it spreads the data over bothe but with JBOD it keeps them on one drive?!?
... and since its a v1 i cant run JBOD.. :(
..found cheap used rnd4000 with 4*1TB Samsung discs in.. but still wants to get this one up and running again!

You are wrong on this. I am running JBOD on my duo v1. If it wasn't possible I wouldn't have asked you about it. I have two data volumes (C and D) - one for each drive.

Based on what we know now, your NAS is fine - the only problem is that one or both disks have failed. With new disk(s) the NAS should be fine. BTW, if you are looking at replacements, you might also price out the RN102. It is faster than your duo (and the rnd4000 v1) and US prices are pretty low. I don't know the current prices for you though (Sweden, correct?)
The question really is whether you want to go down the data recovery path or not. If its of interest, you can contact Netgear and ask about it. All these services are expensive and generally you pay even if the attempt fails.
If you decide to just give up on your data, then try a factory reset with one disk installed. Use RAIDar to set it up as flexraid - then you can use jbod when you get a second disk.
If that fails, take it out and try the other disk. After the install completes, check the SMART stats, just to make sure the remaining disk is healthy.
dont want to pay any big money for Movies and TV-series... just thougt if there was a easy solution!
...and i didnt want to ruin anything if there was a chanse of recover....so X-Raid is the same as JBOD when in a Netgear NAS?
...price on the 4000v1 was so cheap it was a no brainer... can run them both when i get it going!but since i had 2 partitions RAID-0 (or JBOD as you say) one of the discs content would be ok?...
...or shuld i just run them one at a time and see wich one is bad?... what will happen if i remove the pone in 2nd tray?
its the LED for disc 1 that is on when power LED is pulsating...

No. If you'd been running XRAID on your duo you would had RAID-1, with a single redundant 1.5 TB data volume. Exactly what RAID mode XRAID uses depends on the disk configuration. In the NV+ you just bought, XRAID would be RAID-5.

You are confusing me here. If you set up 2 volumes (C and D) then you were running JBOD. If you had set up one RAID-0 volume (C) then you are running RAID-0. JBOD means that each disk is a volume. Partitions are something else.
Did you have two volumes? Or only one?

If the power LED is blinking steadily, the NAS is either booting or shutting down.
A steady disc LED means the NAS thinks the disc is ok. A blinking disc LED means trouble (failed, removed, or resyncing) Off means the NAS thinks there is no disk in the slot.
