I am using SG_IO to issue arbitrary ATA commands. Unfortunately
I can't share that customer code with you, sorry. But have
faith that you can do it. I've not had sg_allow_access()
get in my way doing this - I'll find out why not and report
back; I did not modify sg.c.
Until then, here's the result of an Identify Device (0xec) command:
$ sudo sg_ata sg=/dev/sg5 cmd=0xec buff=1b dev=0x00 style=2 swab=1
