I'd like to see #error here as well, having been bit in the past in
cases of "Oh, redund doesn't work?".

So, you're not adding (and I'm not suggesting you do) SATA to the list

these tests here and elsewhere. Thanks!

Here and elsewhere, please update to use blk_dread, etc, from blk.h to
help future proof this code, thanks!
