Loading/Saving Mesh Data

Can someone tell me the proper way to save the data from a mesh (verts/indices/faces). The code I have below seems to crash on certain meshes, and I believe the problem is simply that there can be more indices than vertices but I don't know how to get the number of indices properly and all. The code I'm currently using is:

MESH::LoadData()
{
        Vertices = new MODELVERTEX[pMesh->GetNumVertices()];
        Indices = new WORD[pMesh->GetNumVertices()];
	Planes = new D3DXPLANE[pMesh->GetNumFaces()];
	byte *ptr=NULL;
	if (!pMesh)
	{
		return;
	}
	DWORD numVerts;
	Mesh.m_NumVertices = numVerts = Mesh.m_pMesh->GetNumVertices();
	DWORD fvf=pMesh->GetFVF();
	DWORD vertSize=D3DXGetFVFVertexSize(fvf);
	WORD* indices;
	HRESULT hr = pMesh->LockVertexBuffer(D3DLOCK_READONLY,(void**)&ptr);
	if(FAILED(hr)) FatalError();
	hr = pMesh->LockIndexBuffer(D3DLOCK_READONLY, (void**)&indices);
	if(FAILED(hr)) FatalError();
	NumFaces = pMesh->GetNumFaces();
	cout << "BEGINNING TO LOAD MESH: " << Mesh.m_FileName << endl;
	cout << "# of Verts:" << numVerts << endl;
	cout << "# of Faces:" << pMesh->GetNumFaces() << endl;
	for (DWORD i=0;i<numVerts;i++)
	{
		Indices[i] = indices[i];
		Vertices[i] = *(MODELVERTEX*)(ptr);
		CenterOfMass += Vertices[i].pos;
		ptr+=vertSize;
	}
	pMesh->UnlockIndexBuffer();
	pMesh->UnlockVertexBuffer();
	for(unsigned int i=0;i<pMesh->GetNumFaces();i++)
	{
		cout << "Loading Face #" << i << endl;
		D3DXPLANE temp;
		D3DXVECTOR3 t0 = Vertices[Indices[3*i]].pos;
		D3DXVECTOR3 t1 = Vertices[Indices[3*i + 1]].pos;
		D3DXVECTOR3 t2 = Vertices[Indices[3*i + 2]].pos;
		D3DXPlaneFromPoints(&temp, &t0, &t1, &t2);
		Planes[i] = temp;
	}
	CenterOfMass /= NumVerts*1.0f;
}

Of course MODELVERTEX is my struct for my FVF (D3DFVF_XYZ | D3DFVF_TEX1). Vertices is a MODELVERTEX*, Planes is a D3DXPLANE* and Indices is a WORD*. Thanks for your help! Edited because I dropped a couple of lines in my copy/paste. [edited by - ms291052 on December 30, 2003 7:42:40 PM]
