[The Solution for Seagate 7200.11 HDDs]

still no luck here... i tried seperating the motor contacts, the head contacts, BOTH, i finally took the PCB off the drive and still am having no luck right at the point where i push "CTRL + Z"... i get nothing, no response at all to the screen

any ideas why i'd get no response to this? i've confirmed my usb->TTL adapter is working, power to the PCB, tried it with and w/out GND connected on PCB.

i'm about out of ideas

f'n seagate...

are you guys connecting GND on the hdd PCB?

[The Solution for Seagate 7200.11 HDDs]

is there any other reason one would get no response to CTRL + Z in HT? My adaptor is working fine (checked it with RX & TX tied)... I've tried flipping TX & RX on the PCB, have tried with cardstock between just the motor contacts, just the head contacts, & both. I've got power to the PCB but am getting no where with this.

Does ground on the PCB need to be connected to anything? I don't see it mentioned in the instructions anywhere but have tried following the fix for this on about 3 different sites and sometimes it makes reference that you need 3 of the 4 pins... I'm at a loss right now

someone please help me!!!! tia
