I was cleaning some junk when I found an old Quantum Fireball 40Gb harddisk. Since it died I always wanted to open it and look inside. Finally I got around to it.
It took a while but I finally pried opened all the seals, but I still could not get the plate off. There was one part near the head controller area where there was a screw with a star head that connected the plate to the main unit. I did not have a star head screw driver and I could not break whatever it was that held the plate to the main unit. So all I could do was swivel the plate.
