ReadFile函数返回错误23

Question

我试图从USB设备（Windows 7）读取数据，但是我收到错误23（ERROR_CRC）。这是我的代码：

int main( int argc, char*argv[])
{
    HANDLE file;
    file = CreateFile(L"\\\\.\\PhysicalDrive1", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_FLAG_NO_BUFFERING, NULL);

    if (file == INVALID_HANDLE_VALUE){
        std::cout << "ERROR opening\n";
    }

    DWORD byte_count;
    GET_LENGTH_INFORMATION source_disklength;
    if(!DeviceIoControl(file, IOCTL_DISK_GET_LENGTH_INFO, NULL, 0, &source_disklength, sizeof(source_disklength), &byte_count, NULL ) ){
        std::cout << "Error "<< GetLastError() << " getting device length \n";

    }
    std::cout << "DISK Length has " << source_disklength.Length.QuadPart << " bytes\n";

    int count = 0;

    DWORD cbRead;
    uint8_t buffer[50 * 1024];
    while (ReadFile(file, buffer, sizeof(buffer), &cbRead, NULL))
    {
          ++count;

    }           

    std::cout << "Read Error " << GetLastError() <<std::endl;    
        return 0;
}

结果是：

DISK长度为16013942784字节

阅读错误23

有人知道为什么GetLastError（）会返回错误，错误的含义究竟是什么？
