Disable single ATA port

I have a laptop, which has a built-in drive on ata2, which went bad. During init, the `udevadm --settle` spins the wheels for over a minute. This is very annoying, and I have not found any way to solve this

`libata.force=2.00:disable` does not have any effect on udevadm, although this option works, when I disable the main drive, the system naturally won't boot.

After udevadm done settling, the system is fully operational, port disabled, and there's no more problems. In other words, `udevadm --settle` somehow disables the port, and it stops becoming a problem

I want to know what it does, so that I could do this myself, and not have to wait for it to probe the knowingly dysfunctional port. I know this could be done by injecting commands into `/usr/lib/initcpio/hooks/udev`

Re: Disable single ATA port

Something different: did you check in the BIOS menus to see if there's a screen where you can disable individual SATA ports?

So open the laptop and pull the offending drive?

Re: Disable single ATA port

bios has no such option

drive is not removable

need to disable drive with software-only means.
