Case of 7200.9

Today, I encountered the typical malfunction for 7200.9 and 7200.10. The following is terminal log for that malfunction:

 

Interface task reset

Buzz – Head Mask FFFF – Switch to full int.

Failed sys sect. write

Unable To Load Overlay 01|000A

 

The solution for such malfunction is to erase G-List or initialize SMART. However, in this case the solution doesn’t work. I got the following error log when initializing SMART:

 

 

That always means bad sectors located in SMART cylinder. In order to prove it I decided to locate head to that cylinder and read content from that cylinder. If there are bad sectors, there will be error message output to log.

 

From the above log, I know there are bad sectors in SMART cylinder. This is the reason causing the malfunction. As it’s physical bad sectors, no solution for that case.
