To day my Seagate ST3000DM001 started clicking when I edited photos i photoshop from it. I turned the pc off, and tried to make a reboot. With no luck of connecting to the disk. The BIOS just what for the disk, and finally to skip it. I think, that it is a bad head? But is there other canaries?
If its the heads i will go for making a head replacement. Scout bee possible to build a clean box for do it in.
