Здравствуйте. Для определения серийного номера жёсткого диска я использую следующий код: [Code] function GetIdeDiskSerialNumber( ControllerNumber, DriveNumber : Integer ) : String; type TSrbIoControl = packed record HeaderLength : ULONG; Signature : Array[0..7] of Char; Timeout : ULONG; ControlCode : ULONG; ReturnCode : ULONG; Length : ULONG; end; SRB_IO_CONTROL = TSrbIoControl; PSrbIoControl = ^TSrbIoControl;
TIDERegs = packed record bFeaturesReg : Byte; // Used for specifying SMART "commands". bSectorCountReg : Byte; // IDE sector count register bSectorNumberReg : Byte; // IDE sector number register bCylLowReg : Byte; // IDE low order cylinder value bCylHighReg : Byte; // IDE high order cylinder value bDriveHeadReg : Byte; // IDE drive/head register bCommandReg : Byte; // Actual IDE command. bReserved : Byte; // reserved for future use. Must be zero. end; IDEREGS = TIDERegs; PIDERegs = ^TIDERegs;
TSendCmdInParams = packed record cBufferSize : DWORD; // Buffer size in bytes irDriveRegs : TIDERegs; // Structure with drive register values. bDriveNumber : Byte; // Physical drive number to send command to (0,1,2,3). bReserved : Array[0..2] of Byte; // Reserved for future expansion. dwReserved : Array[0..3] of DWORD; // For future use. bBuffer : Array[0..0] of Byte; // Input buffer. end; SENDCMDINPARAMS = TSendCmdInParams; PSendCmdInParams = ^TSendCmdInParams;

Под WinXP все работает, а под Win7 не хочет определять серийник, выдает ошибку Code 1. Неверная функция. Може кто знает как с этим бороться

А чем не угодил GetVolumeInformation?

GetVolumeInformation выдает номер лог. раздела, а он может меняться. В общем вопрос решен.
