Any drive as small as that might only support CHS addressing.  I have
one of a similar size that was new in ~1993.  It worked for about 20
years until it was broken in 2013 by dropping support for CHS addressing
in r249083.  The support was under ATA_CAM, and the main point of
r249083 was to remove support for ATA_CAM.  FreeBSD-9 still has this
support, but FreeBSD-10 doesn't.  -current still defines the flag
ATA_D_USE_CHS for using this support, but never uses it.

The error messages from not detecting the non-support for LBA addressing
might be cryptic.  I don't have the old system with this drive online for
testing.  My mail in 2015 to report this gives some boot messages:

Lots of retries, but it times out.  If the DMA worked, that would be worse
since it is for a wrong sector.
