#/sbin/hdparm -i /dev/hda
Provides information on Hard Disk Drive /dev/hda including the serial number.

Does anyone have any idea of getting those serial numbers using C?

I did put the question earlier at :

[Customers hate the idea that if a piece of hardware breaks and must be replaced it also causes random pieces of software to stop working.]

You could do what hdparm does. The current version reads

/proc/ide/hda/identify

and finds the serial number in the 20 bytes starting at byte offset 20. Or get the hdparm source code and look at the file identify.c that's included.

But no other better way. I can try with IP/domain. Actually my application is related to Internet. So, it's not that tough to create a nice/simple interface to support and remove the customers problem to reinstall.

Thanks for your comments. I did not see any file
proc/scsi/sda/identify
Anyway.. I will check for the file identify.c

I don't have any systems with SCSI disks to check on what the equivalent would be, sorry.

hi zahidbd,

I'm not a programmer.  But looking at your requirement, maybe you might want to look at the standard header file in (if you could use that in your code).

/usr/include/linux/genhd.h

cheers.

hello, samri
/usr/include/linux/genhd.h is not talking anything about scsi. "Generic hard disk header file"
Thanks anyway again.

Nothing has happened on this question in more than 9 months. It's time for cleanup!

My recommendation, which I will post in the Cleanup topic area, is to
PAQ, refund points (responses worth keeping even though asker not satisfied).

[I posted the same recommendation in the cross-referenced question http:Q_20554316.html
which had already been visited by CleanupPing.]
