Is there any way to read manufacturer’s serial number from a hard disk
on QNX4. I want to do this from a program written in C.
JQu
A little utility located at
ftp://ftp.qnx.com/usr/free/qnx4/os/utils/disk/idediag.gz seems to do this
however I’ve had bad experiences with this program. (i.e. causes all disk
access to delay indefinitely until reboot) (also no source code)
So to get around that I made a little program that talks to the IDE
controller, sends the ATA Identify Device command and stores the reply in a
shared memory buffer (/dev/shmem/raw_disk_info).
This program is built into the boot file after Fsys but before Fsys.eide
and another program can open the shared memory and read it whenever
necessary.
If there is a more straightforward way of doing this I’d love to see it.

Hello Jason,
I believe I’ve found the straightforward way…
I’m running the code AFTER the system has finished booting, and so far
it hasn’t messed up anything 
If you can enlighten me on how to parse the below buffer output from
the code, I can show you the way:
