Hello John,
It is simple, Western Digital is still selling a lot of SATA drives :)
Haha! Fair enough. I built my first computer without a single AHCI device in it last year, but you can't say the same for my Synology downstairs in my networking closet :)
Ah-ha, that helps explain it :)
If you find other problems, even if you don't intend to fix them, please file a gitlab issue to document that there's work that needs done.
Right now, I don't intend to upstream all my hacky patches to QEMU,
just the things that might be useful for everyone, e.g. GPL and NCQ error log
(and possibly Sense Data Reporting feature set support, and NCQ autosense).
Got it, thanks! I'll try to set aside time to look over your patches "soon", I'd like then for 8.1. If I go quiet, *please* ping me.
