You need to measure the voltages at each if those 4 pins with the board off the drive. That will distinguish the read and write pairs.

The disk without short have terminal access to all comands
but the ATA interface not reconize at all
Then I can't aply the seagate firmware patch
Via terminal there a way to patch firmware?
