Dear amitbhai,
can you access sa.than regenerate module 47.and rewrite it.

This model should have 7 heads. The log shows that it has 1 switched on head. Module 0A is head map module.

What is the log with PCB attached to HDD? Does heads knock and spindle shut down with HDD connected?

It has Head problem. Replaced the head from 2Tb hdd and issue resolved. Thanks,
