hard drive not found

[Ortof]

Hello,

My NAS is currently configured in Raid1 with 2 Western Digital WD40EFZX NASware 3.0 4TB. I want to add two disks to increase my storage capacity.

I have a problem adding the two new hard drives (Seagate IronWolf 4TB ST4000VNZ06 and
Seagate BarraCuda ST4000DM005)

On the nas, the 4 green lights are on, indicating the presence of the hanging disks, but when I enter the nas to configure it, it does not see them.
Result 2 Discs out of 4 recognized and impossible to create a new raid1 or to have my raid 1 evaluated towards a raid 10.

What do you recommend for to succeed in my configuration without losing my data?

Thanks in advance.

please restart your TNAS and try again. If the issue persist, try to clean the superblock on your drives and try again.

NAS nettoyer et redémarré mais le problème est le même.

When I put a hard disk in slot 1 the disk works

It looks like slots 3 and 4 are not recognizing your new hard drive, perhaps because they haven't been used for a long time leading to slot gold finger oxidation, you can try using a toothbrush, eraser, etc to wipe the slot gold finger.

I tried All hard drives on slot 1 2 3 4.
On slot 1 and 2 all disks work (All hard disks are new). On the 3 and 4 None works.

Here is the photo of the hard drive support.

Have you tried to clean the connecting fingers of slot 3 and 4?

[Ortof]
