That's the diagram from the Case Modding FAQ, so I assume these are the pins you are mentioning.

So by switching 23 and 39, along with the standard power, all previous issues concerning the IDE bus deteriation are gone? I'm no expert, but I thought it was grounding issues...

If so, though, this is huge news to me. I was literally one step from buying a new 2 channel IDE PC mobo, and just Samba streaming the large files (Roms, Movies), but this would set me back to my original 3 HDD plan.

I'd like to wait on Opjose, though. He is the resident guru, so I'd like his word on this before taking a leap of faith.

do you already have pictures?
and do you also swith the power to the HDD's
2 switches? 1 for the IDE, and 1 for the power?

Does it work with only switching the IDE-cable?

do you already have pictures?
i took some pics of it in my xbox and it doesnt show it well so tonight i will disasembe everything to give detailed pictures

and do you also swith the power to the HDD's
yes i have a switch for the hds, i put a Y molex and added a switch after it so i can control the power going to each one

2 switches? 1 for the IDE, and 1 for the power?
yes

Does it work with only switching the IDE-cable?
i did not try, i do not want to take any chances getting banned from xbox live or screwing up my xbox, but i would guess it would although not sure

The switch for connector 3 is good

No errors

I'm going to make the switch as you described in option one.
I hope that will work. I'll let you know if it does

I did put a switch on the powercables of the HDD's.

But the x-tender put all of the drives on the same cable.
Is this a better way to do multi hdd ?

Post by: JamesH1985 on October 21, 2004, 01:39:00 PM

i'm not to familiar with the xtender case but whatever it is i am guessing its atleast 50 bucks? this is a cheap alternative i guess if there is a case like that.

I made the switch (option one)
But did not work.

When I put the 2nd disc on the conector, it hangs when booting.
I also tried different jumper settings.

After trial and error you found that 23 and 39 work ?

Wich wires gave you errors?
Have you tried wire 28 and 37 ??

I've found this:
Second oath non removable disk switch off
