You should definitely skip the disk test.
No, you shouldn't.
From my experience it is the best one can do on modern Hardware to check the box "skip the disk check" in the "Pre Boot Menue". It is better to use the Disc Tools once you passed the first stage of booting.
Yes - this is my experience and Yes, I do speak for myself
Just to be 100% clear the disc checker should never be bypassed. I am bit confused what you mean with using the disc tool after the first stage of booting Sigurd. The disc util loads in the ArcaOS installer when you selected your installer type. If you know what you are doing then disabling the disc checker can be an option. But in most cases disabling it will not help the user as minilvm will then run into an issue.
The disc utility does nothing at disc controller level. It only scans the hard discs for LVM information.

It might Sound strange for you, but that is my experience. I would not have been able to install it (ecs, arcaos) several times on modern Hardware, if I would have done it your way. Mini LVM run into Problems when I selected this Option, and I remember eCS 2.0 Beta 6 (or was it 5 or the Silver realease or the first GA...) where this lead to a damaged HDD Layout.... I can not justify what EXACTLY happend, but I never had this Problems when I disabled this Feature.
It only scans the hard discs for LVM information.
This might be a possible thing: .. it may not find LVM Information, and that lead to.....
That reminds me to the time (in 2010) where you several times said that it was impossible to install eCS next to an existing, preloaded Windows 7 System, in the end I had to build this:

Even though, as it seems it did/does not help here, so who cares.
