So far, platter scratches and head damages are one of the most difficult data recovery cases and it’s very important for us to see inside the basics of platters and dumpers. To swap the platter with dumpers is even more difficult.

Precious information stored on platters. Platters made of polished aluminum or glass and covered with several layers of different compounds including ferromagnetic layer which actually stores all the data. As you can see part of the platter covered with the Dumper. Dumpers sometimes called as Separators located between platters, they reduce air fluctuations and acoustic noise. Usually dumpers made of aluminum or plastic. Aluminum dumpers better for cooling air inside HDA.
