Hello,

There are 4 hard drives. I checked the cables by trying other cables.

Thank You

How are you connecting them to the motherboard? Which motherboard are you using?

All these commands show us 3 drives, not 4.

Mainboard is an [

J4105-ITX

the 4 Drives are connected to the SATA Ports

You may be able to import the WD40WDC pool, but the 1 TB drive of WD10WDC is nowhere to be seen. Check its data and power cable, and whether you here it spinning at all.

For import WD40WDC i get that message

root@freenas[~]# zpool import -F WD40WDC
cannot import 'WD40WDC': no such pool available
root@freenas[~]# zpool import -Fn -R /mnt WD40WDC
cannot import 'WD40WDC': no such pool available

Hello everyone,

the problem is solved.

I replaced the picoPSU power supply with a normal power supply and everything is working as usual again.

Many thanks to everyone

Gosh, this would have been obvious. We really need to insist more on getting the FULL hardware specs.

Not technically wrong, the pool is a Redundant Array of Inexpensive Disks :wink:
