Get Hard disk serial Number
Hm, looking at your first set of code, I think you have retrieved (maybe?) the hard drive model. The serial # comes from Win32_PhysicalMedia.
Get Hard Drive model
ManagementObjectSearcher searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach(ManagementObject wmi_HD in searcher.Get())
{
HardDrive hd = new HardDrive();
hd.Model = wmi_HD["Model"].ToString();
hd.Type = wmi_HD["InterfaceType"].ToString();
hdCollection.Add(hd);
}
Get the Serial Number
searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
int i = 0;
foreach(ManagementObject wmi_HD in searcher.Get())
{
// get the hard drive from collection
// using index
HardDrive hd = (HardDrive)hdCollection[i];
// get the hardware serial no.
if (wmi_HD["SerialNumber"] == null)
hd.SerialNo = "None";
else
hd.SerialNo = wmi_HD["SerialNumber"].ToString();
++i;
}

Hope this helps :)

Is the hard-drive serial number with WMIService CHANGEABLE?
Thanks to the comment from FunThomas and after a little troubleshooting with my client, i found out that he is using sometimes an external drive for more space, and when the external drive is plugged in - i'm getting a different HDD Serial-number.
Now i have figured how to get the serial number from the current drive letter.
here is the code for VB:
Dim WMIService As Object, DiskDrives As Object, Drive As Object, DiskPartitions As Object, Partition As Object, SerialNumber, currentDrive
currentDrive = Environ("HomeDrive")
Set WMIService = GetObject("winmgmts:\\" & "." & "\root\cimv2")
Set DiskPartitions = WMIService.ExecQuery("ASSOCIATORS OF {Win32_LogicalDisk.DeviceID='" & currentDrive & "'} WHERE ResultClass=Win32_DiskPartition")
For Each Partition In DiskPartitions
Set DiskDrives = WMIService.ExecQuery("ASSOCIATORS OF {Win32_DiskPartition.DeviceID='" & Partition.DeviceID & "'} WHERE ResultClass=Win32_DiskDrive")
For Each Drive In DiskDrives
Debug.Print "Caption: " & Drive.Caption, "Description: " & Drive.Description, "Name: " & Drive.Name, "Model: " & Drive.Model, "SerialNumber: " & Drive.SerialNumber
SerialNumber = Drive.SerialNumber

How to get hard disk serial number using Python
Linux
As you suggested, fcntl is the way to do this on Linux. The C code you want to translate looks like this:
static struct hd_driveid hd;
int fd;
if ((fd = open("/dev/hda", O_RDONLY | O_NONBLOCK)) < 0) {
printf("ERROR opening /dev/hda\n");
exit(1);
}
if (!ioctl(fd, HDIO_GET_IDENTITY, &hd)) {
printf("%.20s\n", hd.serial_no);
} else if (errno == -ENOMSG) {
printf("No serial number available\n");
} else {
perror("ERROR: HDIO_GET_IDENTITY");
exit(1);
}
Translated into Python on Ubuntu 9.10, it goes a little something like this:
import sys, os, fcntl, struct
if os.geteuid() > 0:
print("ERROR: Must be root to use")
sys.exit(1)
with open(sys.argv[1], "rb") as fd:
# tediously derived from the monster struct defined in <hdreg.h>
# see comment at end of file to verify
hd_driveid_format_str = "@ 10H 20s 3H 8s 40s 2B H 2B H 4B 6H 2B I 36H I Q 152H"
# Also from <hdreg.h>
HDIO_GET_IDENTITY = 0x030d
# How big a buffer do we need?
sizeof_hd_driveid = struct.calcsize(hd_driveid_format_str)
# ensure our format string is the correct size
# 512 is extracted using sizeof(struct hd_id) in the c code
assert sizeof_hd_driveid == 512
# Call native function
buf = fcntl.ioctl(fd, HDIO_GET_IDENTITY, " " * sizeof_hd_driveid)
fields = struct.unpack(hd_driveid_format_str, buf)
serial_no = fields[10].strip()
model = fields[15].strip()
print("Hard Disk Model: %s" % model)
print(" Serial Number: %s" % serial_no)

Apologies for the length, I thought it useful to include the original C struct as a comment. Also, I'm pretty new to both the fcntl and struct modules, so I may be doing something unidomatic. In anycase, run from the command-line (with root privelidges) it looks like this (I've redacted my exact serial for privacy):
fmark@fmark-laptop:~/Desktop/hdserial$ sudo python hd.py "/dev/sda"
Hard Disk Model: FUJITSU MHV2080BH PL
Serial Number: NW--------
What's going on here?
In order to be able to understand what is going on here, you need to look at the #include <linux/hdreg.h> in the original C program. This include imports the HDIO_GET_IDENTITY constant and the struct hd_driveid. I've copied the struct as a comment into the python sourcecode above, so I won't repeat it here. To find out what is going on with HDIO_GET_IDENTITY, grep the source-code for it (on Ubuntu this is at /usr/include/linux/hdreg.h. You should find something like this:
#define HDIO_GET_IDENTITY 0x030d /* get IDE identification info */
Thus, you find that HDIO_GET_IDENTITY is just a constant that tells fcntl that you are interested in getting HD info. As you will notice, that same value (0x030d is an integer in hexadecimal notation) is assigned to a variable in the python code.
Windows
I realise now you are interested in Linux, but I'll keep this here for posterity. The following will get the HDD serial number on Windows (you will need to install the wmi package):
import wmi
c = wmi.WMI()
for item in c.Win32_PhysicalMedia():
print item

How to get hard drive unique serial number in C#
You can try from this source:
As said in the source, a better solution is to get the Hard Drive Serial Number given by the Manufacturer. This value won't change even if you format your Hard Drive.
searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
int i = 0;
foreach(ManagementObject wmi_HD in searcher.Get())
{
// get the hard drive from collection
// using index
HardDrive hd = (HardDrive)hdCollection[i];
// get the hardware serial no.
if (wmi_HD["SerialNumber"] == null)
hd.SerialNo = "None";
else
hd.SerialNo = wmi_HD["SerialNumber"].ToString();
++i;
}
