Hi,

Yes, I will try to do that later.
In the meantime I might have found another problem in hdc.c.
HDC_Cmd_ReadCapacity() increments the DMA address while storing the 8
result bytes but then it explicitly increments the addrese once again by 8:
/* Update DMA counter */
FDC_WriteDMAAddress(nDmaAddr + 8);
I don't think this is correct but rather should be:
FDC_WriteDMAAddress(nDmaAddr);
Take care
Uwe
