About ide mod

Thank you so much for your reply.
But I have a question about attaching Hard Drive to the dreamcast.
I have found below links which shown whole pinout of IDE 44pin cable and its corresponding pin number of DC mainboard.

and I have compared it to "PCB Layout of G1-ata" and found that It links all ground pin of IDE cable to only one point(A8 point,ground), while G1-ata links all of IDE's ground with A24 and B24 point(P.GND) as well as A8 point.
It seems deliberately separate A24,B24 point (P.GND) from GND of IDE cable,it is opposite to G1-ata(G1-ata Author seems to want to link all of GND together on each other.)

Don't I have to worry about separating P.GND from Normal GND , and It doesn’t matter to link P.GND with all of Normal DC GND and GND from IDE cable when I try to wire hdd IDE cable modification?
