Thank you for this information, I managed to restore a clients hard drive using it Though I found the instructions on this page a little easier to follow and apply (not sure who the author is though). https://sites.google.com/site/seagatefix/Home They suggested using a small piece of cardboard to break the connection between the PCB and the head contacts during the spin down phase. I removed the 2 screws near and to the bottom left of the head contacts to allow the cardboard to slide in/out. I also loosened the long screws near the corner edges. After I performed the spin down I then gently removed the cardboard and carefully inserted just the one the screw near the head contacts (helped to use a magnetic tip to position the screw), as that seemed to be the simplest and most efficient way to do it. I had the "Error 1009 DETSEC 0000600" when trying to spin the drive up. A quick fix for me was to simply place a piece of cardboard on top of the PCB (to shield from any electrical discharge) near where the head contacts are and apply some gentle pressure with my finger then try the spin up command again. That allowed me to restore the drive, though cleaning the contacts can also help prevent any further problems. I hope that helps.
