Ubuntu硬盘健康诊断实战：SMART监控与寿命预测指南硬盘健康是Linux系统稳定运行的底层基石，其核心在于对SMART（Self-Monitoring, Analysis and Reporting Technology）数据的准确采集、语义解析与趋势建模。SMART并非万能体检报告，而是由硬盘控制器生成的协议级状态快照，需结合ATA/NVMe双协议差异、厂商定制属性映射及版本兼容性进行深度解读。在Ubuntu环境下，smartmontools作为原生工具链，承担着从寄存器读取、协议翻译到阈值判断的关键角色；其价值不仅在于‘显示数据’，更在于支撑可回溯的健康阅读详情

各位大佬，请问想获取NVME接口的硬盘的主控和固件信息，代码思路如下：
/////////////////////////////////////////////////////////////////////////////////////////////////////////
typedef struct _SCSI_PASS_THROUGH_WITH_BUFFERS24 {
SCSI_PASS_THROUGH Spt;
UCHAR SenseBuf[24];
UCHAR DataBuf[512];
} SCSI_PASS_THROUGH_WITH_BUFFERS24, *PSCSI_PASS_THROUGH_WITH_BUFFERS24;

/////////////////////////////////////////////////////////////////////////////////////////////////////////
BOOL bRet;
DWORD dwReturned;
DWORD length;
SCSI_PASS_THROUGH_WITH_BUFFERS24 sptwb;

HANDLE hDevice = CreateFile("\\\\.\\PhysicalDrive2", GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, 0, NULL);

if (hDevice == INVALID_HANDLE_VALUE)
{
fprintf(stderr, "#####:Error:%ld\n", GetLastError());
return FALSE;
}

::ZeroMemory(&sptwb, sizeof(SCSI_PASS_THROUGH_WITH_BUFFERS24));

sptwb.Spt.Length = sizeof(SCSI_PASS_THROUGH);
//......
sptwb.Spt.DataBufferOffset = offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS24, DataBuf);
sptwb.Spt.SenseInfoOffset = offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS24, SenseBuf);

sptwb.Spt.CdbLength = 16;
//......
sptwb.DataBuf[0] = 1;

length = offsetof(SCSI_PASS_THROUGH_WITH_BUFFERS24, DataBuf) + sptwb.Spt.DataTransferLength;

bRet = ::DeviceIoControl(hDevice, IOCTL_SCSI_PASS_THROUGH,
&sptwb, length,
&sptwb, length, &dwReturned, NULL);

if (bRet == FALSE)
{
::CloseHandle(hDevice);
return FALSE;
}

sptwb.Spt.CdbLength = 16;
//......

bRet = ::DeviceIoControl(hDevice, IOCTL_SCSI_PASS_THROUGH,
&sptwb, length,
&sptwb, length, &dwReturned, NULL);

if (bRet == FALSE)
{
::CloseHandle(hDevice);
return FALSE;
}

DWORD count = 0;
for (int i = 0; i < 1024; i++)
{
count += sptwb.DataBuf[i];
}
if (count == 0)
{
fprintf(stderr, "#####:Error:%ld\n", GetLastError());
::CloseHandle(hDevice);
return FALSE;
}

fprintf(stderr, "Buf:%s\n", sptwb.DataBuf);

::CloseHandle(hDevice);
/////////////////////////////////////////////////////////////////////////////////////////////////////////

请问为啥sptwb这个获取为空呢？？像NVME接口的硬盘如何获取它的主控和固件信息呢？
