Suitable harddisk model to use it's servosystem to build a DIY low-cost shutter. This picture was taken by scanning the harddisk on the flatbed of my HP All In One printer. To get the servosystem out of the harddisk the following tools are needed : - One Torx T8 or a normal 2.5 mm (not recommended) screwdriver for most of the screws. - One 8 mm screwdriver to remove the central servobolt. - A cutter or pince to remove the read / write amplifiers and wiring. - 20 minutes time ... Required steps to remove the Servosystem from the Harddisk Step 1 Remove the cover of the harddisk - remove the 7 screws (one screw sits below the label ! - see picture). Step 2 Remove the dust protection tape on the side of the harddisk. Step 3 Remove the 6 screws and the cover from the platter. Step 4 Push black plastic lever toward the center. Move the Servosystem arm now to the outside of the platter. Step 5 Unscrew the 3 screws from the servosystem. One srew with the 8 mm srewdriver and two screws with the Torx T8 screwdriver SIMULTANEOUSLY to avoid damage to the Servo-anchor ! Step 6 Try to remove the platter(s) from the harddisk now ... Be careful not to damage the Servo-anchor. Step 7 Remove the Servosystem and its connectionblock. Step 8 Cut the flatcable form the connectionblock if You like to use your own connection cable. Otherwhise you can use the existing flatcable and findout its two coil connections ... Step 9 Remove all the read / write stuff (glued) from the Servosystem arm(s) with a pince. Step 10 Saw off at least one arm till the base of the servosystem. Step 11 Remove the flatcable from the solenoid with a 50 Watt or lower soldering iron. Step 12 Solder two wires (stripped from an old harddisk flatcable) to the solenoid pins. This is the most critical part of the operation ! Mark at least one wire because the Servosystem is polarised. The manner how a DC voltage is connected to the solenoid determines the direction of move of its anchor. Step 13 empty step - to dangerous to specify one : > ) Step 14 The servosystem can now be further adapted and modified as a nearly zero-cost DIY Shutter system. Step 15 Test the Servosystem outside the harddisk with a 5 to 9 Volt (block)battery. Remember to change the polarity if nothing happens ... Good Luck ! Frans (alias Arnoldus)

one cellphone was brutally harmed in the making of this production. The LCD screens are hopefully going to be cross sectioned and then viewed in a SEM. Either that or I'm gonna fail a project bigtime. Cross whatever ya got!
