If I turn off power and again power On it, it again stays BSY and have to repeat the same procedure to get it READY.
What is the problem? what should i do now ??

best regards.

The drive has bad heads. Open the drive in clean room, check heads under microscope, clean or replace heads.

This model has 2 heads and I checked, the heads are healthy.

But "FAIL Servo Op=0155 Resp=0007" says something else, try with a new set.

I also tested with new heads, But the result was the same.
