I have an EX4100 with 2 x 4TB Red disks in RAID 1.
First, one of them changed the case led from blue to red. Now both led are red.
Diagnostic indicates:
disks are OK
RAID is deteriorated.
In one of shared folders, a lot of pictures (those of our marriage and kids, between others) are not shown anymore even if they are there because the disks are still full at 95% .
I’m transferring the second shared folder that seems to have all the data OK, to a new disk.
How can I restore the lost pictures ?
Is a good idea to delete the second folder once transferred ?
Any fix or idea is welcome, if I don’t answer is because my wife already killed me
Hi Cerberus … I have no idea of what is that (I’m going to read about), and for now I think it’s better to wait the second folder transfer to finish, no?
It will take 2 more hours.
Mi problem is with disks on slots 1 and 2 (volume 2), are the commands still the same ?
I know you know but I don’t know at all how to do that, the link you send doesn’t explains all but there other links on that post, so, to do what you’re asking I need to read.
I send you the results once I have them, probably tomorrow and one more time thank you for your help!
Nothing is crystal clear for me because I don’t know nothing about it but I will find, I’ve installed PuTTY need to know what is it and how to use it … take some rest and thank you.
Forum doesn’t allow me to post all the information,
I already did what you ask but the information seems to be for the my news 10TB, my problem is in the old 4TB
The WD NAS boxes run a customized version of the Linux O/S.
The dashboard you normally access through settings is a simple graphical user interface to the Linux O/S.
Using putty; you are essentially opening a “command line window” into the WD Nas box; which then allows you to enter Linux O/S commands. This is exactly like opening a Command Prompt window in Windows; and then executing DOS commands.
The commands he is having you enter are disk diagnostic commands which will provide much more information than the read-outs available on the WD NAS dashboard. From your description; the money is on ONE of the two drives being bad. . .and it needs to be replaced.
You ALWAYS want a backup for any data on ANY system. So - - -starting by getting data off the NAS is a good start.
Not sure what you mean by “deleting second folder”. Is this a second share on the drive? and between the two shares the drive is 95% full?
I wouldn’t delete anything just yet. And since this is Raid 1; the two drives should be duplicates of each other. There are multiple ways to access data on the disks. . . how are you doing it?
Are you using windows file explorer or MAC finder?
are you using the web app?
You can also access the files (in the Linux directories on the drive) directly using WinSCP. OR - - you can pull the drives and access data directly using a PC (and a Linux reader program) (but you are not to that point yet)
What do you mean “information seems to be for my news 10TB, my problem is in the old 4tb”.
Did you do something like swap disks in the unit?
For Raid 1 to work properly; both disks must be the same size. If they are not; the “Raid array” will be the size of the SMALLER drive.
There is a way to migrate from 2 x 4tb to 2x10tb; but there are a number of steps along the way.
Try rebuilding the RAID first. If that doesn’t work, consider using data recovery software for the missing pictures. Hold off on deleting the second folder until you’re sure your data is safe.
I have 2 x 4 TB Red RAID 1 in slots 1 and 2, I have 2 shared folders on them. One of the disks started to show the “deteriorated” status. Disks are full at 95%.
I bought 2 x 10 TB Red Plus.
To be safe I turned off the system, I pulled out the 2 x 4 TB from slots 1 and 2 and I inserted the 2 x10 TB on slots 3 and 4. I formatted them RAID 1.
Turned system off again and I reinsert the 2 x 4 TB on slots 1 and 2.
So now I have the 4 slots filled.
Don’t know exactly when, the second 4TB disk started to show the deteriorated status.
On the 2 x 4 TB I have 2 shared folders, I succeed to transfer one of them to my 10 TB using Windows file Explorer transfer, so I thought maybe to delete it to have more space in the disk (not done yet).
On the other shared folder (with the pictures) all the folders starting by numbers (Ex. 20211031_Eva 1st year birthday) are missing, at least using my file explorer on Win10.
I executed the commands requested by Cerberus but the information seems to be for the 10 TB disks only, I will post the results tomorrow in many pieces.
If you have any idea let me know please and thank you for your help!
Enable SSH, then run the following commands, one at a time, and post the results. Run a single command, post the results of that command, then run another command, etc…

So I sent you the 4 prints, as said, problematic discs are in commands sdc, sdd.
Also sent them in text format, divided in 2 posts per command, so 2 first text posts are command sdc and last 2 text posts are for command sdd.
