  • get pnpdeviceid
  • get instancename of pnpdevice accordingly
  • get s.m.a.r.t data instancename

example code

public string   pnpdeviceid     {         set         {             this.m_pnpdeviceid = value;             this.instancename = null;             this.queryobjatapismartdata = null;              searcherpnpdeviceid = new managementobjectsearcher("root\\wmi", "select * mswmi_pnpdeviceid");             foreach (managementobject queryobj in searcherpnpdeviceid.get())             {                 if (queryobj["pnpdeviceid"] != null)                 {                     if (this.pnpdeviceid.toupper() == queryobj.getpropertyvalue("pnpdeviceid").tostring().toupper())                     {                         if (queryobj["instancename"] != null)                         {                             this.instancename = queryobj["instancename"].tostring();                             break;                         }                     }                 }             }              if (this.instancename != null)             {                  searcheratapismartdata = new managementobjectsearcher("root\\wmi", "select * msstoragedriver_atapismartdata");                 foreach (managementobject queryobj in searcheratapismartdata.get())                 {                     if (queryobj["instancename"] != null)                     {                         if (this.instancename.toupper() != queryobj.getpropertyvalue("instancename").tostring().toupper())                         {                             continue;                         }                     }                     this.queryobjatapismartdata  = queryobj;                     break;                 }         }

}

after that, properties of queryobjatapismartdata
