如何使用 获取驱动器serial number的？hard disk`Python`Linux
我想使用 Python 模块来执行此操作，而不是运行诸如 之类的外部程序hdparm。也许使用fcntl模块？
解决方案 1：
Linux
正如您所建议的，在 Linux 上可以使用fcntl来实现这一点。您要翻译的 C 代码如下所示：
static struct hd_driveid hd;
int fd;
if ((fd = open("/dev/hda", O_RDONLY | O_NONBLOCK)) < 0) {
printf("ERROR opening /dev/hda
");
exit(1);
}
if (!ioctl(fd, HDIO_GET_IDENTITY, &hd)) {
printf("%.20s
", hd.serial_no);
} else if (errno == -ENOMSG) {
printf("No serial number available
");
} else {
perror("ERROR: HDIO_GET_IDENTITY");
exit(1);
}
在 Ubuntu 9.10 上翻译成 Python 后，它的内容有点像这样：
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)

抱歉写得太长了，我觉得把原始的 C 结构作为注释很有用。另外，我对fcntl和struct模块都很陌生，所以我可能做了一些不合逻辑的事情。无论如何，从命令行运行（使用 root 权限），它看起来像这样（为了保护隐私，我删去了我的确切序列）：
fmark@fmark-laptop:~/Desktop/hdserial$ sudo python hd.py "/dev/sda"
Hard Disk Model: FUJITSU MHV2080BH PL
Serial Number: NW--------
这里发生了什么事？
为了能够理解这里发生了什么，您需要查看#include <linux/hdreg.h>原始 C 程序中的。这包括导入HDIO_GET_IDENTITY常量和 struct hd_driveid。我已将结构作为注释复制到上面的 python 源代码中，因此我不会在这里重复。要找出发生了什么HDIO_GET_IDENTITY，请在其源代码中查找（在 Ubuntu 上为）/usr/include/linux/hdreg.h。您应该找到类似以下内容：
#define HDIO_GET_IDENTITY 0x030d /* get IDE identification info */
因此，您会发现这HDIO_GET_IDENTITY只是一个常量，它告诉 fcntl 您有兴趣获取 HD 信息。您会注意到，相同的值（0x030d十六进制表示的整数）被分配给 Python 代码中的一个变量。
视窗
我意识到你现在对 Linux 感兴趣，但我会把它保留在这里以供后人参考。以下将获取 Windows 上的 HDD 序列号（你需要安装wmi 包）：
import wmi
c = wmi.WMI()
for item in c.Win32_PhysicalMedia():
print item
解决方案 2：
拿一把螺丝刀打开盒子；-)
如果你使用的是 Windows，这个可能会有用
import win32api
print win32api.GetVolumeInformation("C:\\\")
为此，您需要适用于 Windows 的 Mark Hammond 模块
http://python.net/crew/mhammond/
解决方案 3：
在 Windows 上，您也可以使用subprocess内置的 获取它！
import subprocess
serials = subprocess.check_output('wmic diskdrive get SerialNumber').decode().split('
')[1:]
serials = [s.strip() for s in serials if s.strip()]
如果您还需要其他信息，如索引和制造商：
import subprocess
serials = subprocess.check_output('wmic diskdrive get Index, SerialNumber, Manufacturer').decode().split('
')[1:]
有关可用属性的列表，请查看此文档。
解决方案 4：
视窗
def get_serial_number_of_physical_disk(drive_letter='C:'):
import wmi
c = wmi.WMI()
logical_disk = c.Win32_LogicalDisk(Caption=drive_letter)[0]
partition = logical_disk.associators()[1]
physical_disc = partition.associators()[0]
return physical_disc.SerialNumber
例如：
get_serial_number_of_physical_disk(os.getenv('SystemDrive'))
将为您提供包含逻辑系统驱动器的磁盘的序列号。
解决方案 5：
对于 Windows
import os
data = os.popen('vol '+'c:', 'r').read()
data = data.split()
print(data[len(data)-1:])
