Hard disks are an essential part of our computers and all our precious data is stored in them. You may be curious to know how is the inside of a hard disk, so we have?disassembled?one for every one to see.
First it is very important to note that hard disks must have the right pressure to work properly. To achieve that, all hard disks have a small hole for pressure equalizing, of course the hole is protected with a filter so that impurities will not enter.
If we open the cover we will see several plates where the information is stored and the heads that moves over the plates to read and write the information. The speeds and acceleration of the plates can go up to 550G. ?That’s faster acceleration than any missile.
When a mechanical failure occurs the plates can be taken from the hard disk for data recovery. In this case a special clean room is needed, because if dust touches the plates it may not be possible to recover the data. In this case we were going to destroy the hard disk for our customer so dust did not matter.
