automatic native command queueing
 
Is NCQ(Native Command Queueing) usually automatically enabled by libata when a disk supports it? I am using libata.force=ncq in my command line and wonder if forcing it might hurt the drive.

In AHCI mode NCQ is automatically enabled. I doubt that enabling it will hurt the drive. You can check if it is enabled if you run:

Code:
dmesg | grep ncq
or there might be other ways.

How can I tell if my motherboard supports AHCI?

It should be in the manual or the BIOS options, check the SATA controller options.

If it says no under NCQ for my chip (https://ata.wiki.kernel.org/index.ph...dware_features), forcing it will do nothing?

If it says that it is not available, then yes forcing it will not do anything.
