Hello, I am trying to get 4 2tb HDDs for a pool I want to create (it was existing but it wasnt working so decided to recover all the data and try this method) I do lsblk -o name,serial,type,size,fstype,partuuid and I can see all 4 drives but Storage>Disks only sees sdf?

They all have the same serial number. How are they connected? USB case? SATA card?

Not if you don’t post you complete hardware. Seriously all we can do at this point is guess

I have no idea what the hardware is, but I am on TrueNAS-Scale (ElectricEel-24.10.2.4)

That’s why. You shouldn’t use those with TrueNAS or ZFS.

I got the USB Case so I could cool all the drives down and have them all in 1 place, what else can I do?
