[src/trunk]: src/sbin/atactl "smart status" already obtains the ata parameter...
details: https://anonhg.NetBSD.org/src/rev/21d10878e81a
branches: trunk
changeset: 446435:21d10878e81a
user: mrg <mrg%NetBSD.org@localhost>
date: Wed Dec 05 06:49:54 2018 +0000
description:
"smart status" already obtains the ata parameters to check if smart
is actually supported, so we can attempt to guess a vendor smart
table from the model name. add basic support for all the micron /
crucial disk names i could find, and add a couple more micron
specific values.
XXX: probably should add regex support for matching, and probably
should be more restrictive with the current matches.
