Re: Adam Lanzas hard drive Part of my job requirement is data destruction along with recovery.
Put the drive through a degausser, then a crusher. Model we are using right now puts a bolt through the platters (actually through the top, platters and out the controller board).
The magnetic field destroys any data track and if not, the physical destruction prevents removal of platters and any cache (chips).
Mind you, most 2.5" HDDs have glass platters (Hitachi/IBM/Toshiba). The platters shatter into bits (pun) when crushed.
With forensics, if the controller is intact, the cache and buffer may still have data. If the platter(s) are intact, they can be transferred to a slave (same model, heads).
If interested in more info in drive forensics, Scott is a good source and trainer: »www.myharddrivedied.com/
Reads like this neo-adult tried to cover tracks. Pretty messed up.
