While this trick will not work on all bricked HDDs, if you have a Seagate 7200.11 HDD that is failing because it is convinced it is always in a busy state then you should check out this story on Hack a Day.  While the initial step of detaching the circuit board and blocking some connections with piece of cardstock can be handled with easy, it will take some expertise to use an Arduino or serial-TTL converter to issue commands to the HDD controller.  It is a good thing that there is a tutorial to walk you through the steps to unbrick your HDD, besides in the worst case scenario your HDD will still be a brick so it is worth a shot.

"Hard drive firmware is about the last place you want to find a bug. But that turned out to be the problem with the Seagate HDD which he was using in a RAID array. It stopped working completely, and he later found out the firmware has a bug that makes the drive think it’s permanently in a busy state. There’s a firmware upgrade available, but you have to apply it before the problem shows its face, otherwise you’re out of luck. Some searching led him to a hardware fix for the problem."
