The FAIL Servo Op=0195 Resp=0007 keeps coming and never end and the hdd doesn’t enter F3 T> at all.

The is actually the heads damage, exactly speaking, the heads were downgraded and very weak and cannot read the platter surfaces properly at all.

So users need to use Seagate LM Slim HDD Head Comb Suite.Advanced to separate the heads and swap the heads with donor ones in clean room.
