I don't have the needed equipment to read the ram, so good luck to anyone.

TS: so yeah, you were right...

its just taken from the spec of a hard drive.. this document to be exact:

to me, segmented buffer "used for firmware" simply means that firmware is copied in top of ram.... there is also an "overlay firmware" of 1,5mbit on disk, i doubt it could be run from here.

lol yep, therefor, connect to the 360, start up, read out the firmware, so don't have to copy from the asic

reread this entire thread, please

I'm using a sat-pata converter because my motherboard is VA chipset and can't remap to primary and secondary channels.
The other 2 jumpers are one connected directly to the main Marvell chip, the other to the motor driver by a resistor and a capacitor, i'll try it later.

i'll have a dead hd next to a dead 360 soon

I know that this thread is VERY old, but did you get any more info on the serial commands?  I'm looking to change the serial number on a 20GB Samsung HD.

I suggest that you ask that on HDD/data recovery forums. The chance you get an useful answer there is like 90% bigger.
