Windows Driver Kit DDI reference (ni-ntdddisk-ioctl_disk_verify)

IOCTL_DISK_VERIFY IOCTL

Description

Performs verification for a specified extent on a disk.

Parameters

Major code

Input buffer

The buffer at Irp->AssociatedIrp.SystemBuffer contains the VERIFY_INFORMATION data specifying the starting offset and length to be verified.

Input buffer length

Parameters.DeviceIoControl.InputBufferLength indicates the size, in bytes, of the buffer, which must be >= sizeof(VERIFY_INFORMATION).

Output buffer

None.

Output buffer length

None.

Input/output buffer

Input/output buffer length

Status block

The Information field is set to zero to prevent the I/O manager from copying data from SystemBuffer back into the user area.

If the request is successful, then the Status field is set to STATUS_SUCCESS. Otherwise, the Status field can be set to STATUS_BUFFER_TOO_SMALL, STATUS_INFO_LENGTH_MISMATCH, STATUS_INVALID_PARAMETER, STATUS_INSUFFICIENT_RESOURCES, STATUS_NONEXISTENT_SECTOR, STATUS_DEVICE_DATA_ERROR, STATUS_INVALID_DEVICE_REQUEST, STATUS_IO_TIMEOUT, or STATUS_DEVICE_NOT_CONNECTED.

Win32 API reference (ni-winioctl-ioctl_disk_verify)

IOCTL_DISK_VERIFY IOCTL

Description

Verifies the specified extent on a fixed disk.

To perform this operation, call the DeviceIoControl function with the following parameters.

BOOL DeviceIoControl(
  (HANDLE) hDevice,             // handle to device
  IOCTL_DISK_VERIFY,            // dwIoControlCode
  (LPVOID) lpInBuffer,          // input buffer
  (DWORD) nInBufferSize,        // size of input buffer
  NULL,                         // lpOutBuffer
  0,                            // nOutBufferSize
  (LPDWORD) lpBytesReturned,    // number of bytes returned
  (LPOVERLAPPED) lpOverlapped   // OVERLAPPED structure
);

Parameters

Input buffer

Input buffer length

Output buffer

Output buffer length

Input/output buffer

Input/output buffer length

Status block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful.

Otherwise, Status to the appropriate error condition as a NTSTATUS code.

For more information, see NTSTATUS Values.
