We have had a winner!

The 1.8" Kingspec IDE/PATA drive I found on Amazon Canada: https://www.amazon.ca/gp/product/B0099395FA/
Builder (v6) worked without fuss, and I then installed the v3b11+Hijack .upgrade over that, again totally fuss-free.

The drive even has screw holes for mounting, two of which match the empeg's drive sled.

I suppose I might order a second one for here, while they're still available.

EDIT: Drive/firmware identification data below. One difference between this one
and the fake Yansen drive, is no mention of the "Security Mode feature set" on the genuine article (below).
Another difference is that the Yansen drives are native SATA (not PATA), but with a conversion chip onboard.
The SATA settings also show up in the drive identification data for those, but not for the genuine Kingspec.
Also, jumper settings are documented, and it WANTS the jumper in place for MASTER (opposite of the diagram we found earlier).
