Kindly offline I'm told `man sg_scan` may have changed lately.  I have
sg installed without root privilege, so I have no man, but my sg_scan.8
is readable.

There I see only the -anwix options defined, in particular the
predefined -a and -n device lists.  I see no support for accepting a
list of devices to try from the command line.  I will write a patch and
reply again.

1.06 of Mon differs from 1.06 of Fri, aye.  My diff -Nurp between those
yields 1432 lines.  I see CHANGELOG mentions: "accept /dev/hd? ATAPI
devices directly in lk 2.6", I thank you!

Lost me help?  I'm guessing this English means an "st device" is a PDT
x01 device aggressively supported by CONFIG_CHR_DEV_ST, and we (lk 2.6)
have history that precludes sg_scan from seeing st devices, and osst is
something like st but distinct.

Answered separately in this same thread.  Now I see gcc also complains
of sgm_dd.c.

$ sudo ./sginfo -a /dev/hdc | wc -l
    223
$ sudo ./sginfo -a /dev/hdd | wc -l
    117

Fun thank you.
