I received two drives on the same day exhibiting the same problem. Both are Seagate ST31000528AS, both clicking, shutdown, and identified as St_M13FQBL
According to the following article ...
http://www.salvationdata.com/blog/error ... r-7200-11/... your drive could have a head problem, firmware problem or bad sector problem. The result is that the drive is unable to read the firmware which is located in the hidden System Area on the platters. It then reverts to identifying itself with a factory alias (ST_M13FQBL) which is stored in the serial flash memory chip on the board.
The Salvation Data article states that it may be possible to "solve it as fix the LBA=0 problem (yes, the LBA=0 problem caused by verify code error)."
Although the article refers to the 7200.11 drives, I have seen statements by data recovery professionals that the 7200.11 LBA=0 fix can also be applied to the 7200.12 models.
Of course you need to be able to communicate with the MCU ...
