I assume it will be in NetBSD-current (9.99.x) and NetBSD 10 as well?

This sysctl seemed to have no effect, I still get the same trouble though it may take a few days following reboot and fsck_ffs to show up.

Now the question is whether there is any point going further in NetBSD, like 9.99.26 and later, on this hard drive.  That is the point of this late followup post.

I could still try with FreeBSD, Linux and/or Haiku.

I have the other hard drive (Hitachi 4 TB refurbished special) in a hard-drive (SATA) dock that is part of the computer case.

I could even install NetBSD on a USB 3.0 external hard drive (Seagate Expansion), would that work?

I already have NetBSD installed there (8.99.51 amd64 and i386) and could update there but would have to rebuild packages almost from square one, and not mount anything on that WD Green hard drive when NetBSD is running.

I could even (is it safe from NetBSD?) put /home partition on ext2fs to be accessible from NetBSD, FreeBSD, Linux, and even Haiku.
