Where is the Wipe option to format disk

TrueNAS General
1

I’ve googled this but can’t see the ‘wipe’ option anywhere.
I am running TrueNAS Scale ElectricEel-24.10.2.1 , and I want to format a disk which has failed the last 23 smart tests.
I go to Storage/Disks, find the disk I want, then Manage Disks/select disk/Edit, and all I see is General, Temperature, Power, and Smart.
According to this:

The wipe option is supposed to be next to the SMART test Test Results, but it is not there on my NAS.

So I guess I can’t wipe any disks now??
So where do I find the Wipe function or option

Thanks to whoever put the link up, but I read that before I edited my post. And as I said , the wipe function is supposed to be next to the SMART test results, but it isn’t on my NAS.
What else can I do

Is the disk still used? If so, did you read this line:

" TrueNAS only shows the Wipe option for unused disks."

This is what my experience has been though it has been awhile since I needed to setup previously used disks.

Unused disks are disks without any previous or current array setup on them and are not in use.

If they were previously used in a NAS or had any kind of raid setup, then Truenas will likely recognize this fact and they will generally not show up in Truenas. This is actually a good safety factor so an existing array is not accidentally destroyed.

If this is the case or suspected, then you could use dd from the command line to wipe the disk dd if=/dev/zero of=/dev/sdX bs=1M
Replacing X with the desired drive. Be sure to double/tripple check you have the right drive as it will destroy all data on the selected drive.

@PhilD13, thanks for the information and the cmd line to wipe the disk in a shell.
