There should be a chip on the port where you connect your video cables (if it's a RGH)
And for JTAG, there should be some diodes and extra resistors here
I must say that your text is quite hard to comprehend.
So, basically you did have a JTAG one?
And everything works right now?
It's well known in the jtag/rgh community you should have a official internal hard drive of some sort
It's the only thing you can do right now.
No.
I and various others are using normal 2.5 inch laptop drives in various sizes and I have never had any problems.
The hacked NAND removes the check for a security sector so it will accept any sized FATX drive.
Yeah that works too my point was he shouldn't be using a usb flash drive as his main hard drive, just asking for problems.
