Hi everybody
I have seagate ST31000528AS 7200.12 with a bad SMART (no access to DATA). I want to clear the SMART but I don't why I have no access to terminal. I tries to access to terminal with another HDD, I succeded (It means that my terminal card is working)
Acelab told me that I need to short circuit this drive, but first I first I should identify the pins (which I don't know)
here are the picture of the PCB (front and back)

Hint: check the commonality of all PCB cases and their shortning points presented by Ace in their Seagate F3 manual/document.

I have some examples for various drives:

The read test points can be identified by a single resistor (eg 100 ohm) connected across the differential pair at the MCU end.

The write test points are either not externally terminated, or they may have a 50 ohm resistor between each member of the differential pair and ground.

Hi, first I would like to thank you: fzabkar, freakzy and labtech for the replay.
I think I found it

When short circuiting the points, the hdd recalibrated thats all, nothing happened, still have no access to the terminal (unselected)

Anyone had the same case
