Hi guys, extreme help required.Added a second 4TB WD RED into slot 2 of my RN104 NAS tonight and everything started off ok and then suddenly I have the following flashing at me every few seconds..data:DEGRADEDNow I am totally new at this, so I am now worried - I have read a bit about this prior to writing this but it is still a bit confusing.All my data is still on the 4TB in slot 1Currently the drive in slot 2 is not showing at all. The system is showing that slot 1 has a drive and slot 2 has nothing even though there is a drive their.Also noticed that prior to inserting the new drive into slot 2 the RAID was JBOD and now it is saying RAID 1How do I fix this ?I just wanted to add the second 4TB WD drive so to add more data as the slot 1 drive is nearly full - currently 755.41GB Free out of 4TBPlease help !Many thanks in advance

Is the 4TB you have inserted a brand new one or used? Might as well check the drive with manufacturer diagnostic tools like seatools or WD lifeguard.

Brand new - just got it this evening - delivered

Thanks lads, will do so tonight when I get home from work.Much appreciate the help and suggestions. I hope the change in RAID has not effected the data in any way.So the disk you added was used to add redundancy, not to add an additional volume.Was there a way to prevent this ?Can I change the RAID back to JBOD ?Talk later NJP

So the disk you added was used to add redundancy, not to add an additional volume.

Was there a way to prevent this ?

Can I change the RAID back to JBOD ?

Talk later

The data would still be there.

You could have disabled X-RAID before adding the second disk. Too late for that now.

Could be a good opportunity to update to the latest firmware if you have not already, backup your data, do a factory default (wipes all data, settings, everything), disable X-RAID, destroy the volumes, create the volumes you want etc.

You would need to destroy the volume (deletes all data) and create new volumes.

Oh crap - thats a chore and a half !

Considering there are the bones of 3TB of data and don;t have the room to backup to.
Going forward I just need to run the diagnostic software on the new drive and see what that comes up with. From there what would I need to do - re-format the new drive ? and then insert it back to the NAS and what - don;t really understand the ins and outs of it clearly yet.

A very nervous user :(

Well if you can't backup your data it clearly is not that important. No important data should be stored on just the one device.

If the drive is O.K. you could delete the partitions off it and try adding it again (to the same slot as before). If it is bad you would need another disk.

Adding the second disk would add redundancy. Using X-RAID you could then add a third disk to expand the volume.

The data is important and I do have external drives but just need to carry out a major tidy up of all data on those HDD to have the space to move the data from the NAS slot 1

It's the thoughts of it that is scary !! :)

Could take a while to move the data from the 4TB to different external hdd's

But we learn from our mistakes or lack of knowledge I suppose ;)

Just as a matter of interest - how do you go about deleting the partitions off the new HD
I might try that after running the diagnostic tools.
I will put up the reports on the drive later

Thanks again

On a windows PC there are two ways to delete partitions.

One is to use the diagnostic utilities (e.g., seatools or lifeguard) to zero the drives. One of them (I forget which) has a quick erase (zeroing sectors at the beginning and the end) which is enough to delete the partitions.

The second way is to right-click on "computer" and select "manage". A management tool is launched. Scroll down to the disk manager section, and right click each "volume" of the disk. Then choose delete. This will work even if Windows doesn't recognize the disk format (which it doesn't).
