I had a discussion with a customer who requires the physical destruction of the PC (a standard laptop) which is holding their data. After clarification, they mean the destruction of the entire laptop, not the disk only (the disk is removable so it would not have been a big deal).
I am putting the cost and ecological aspects aside - is there a standard which encourages, recommends or forces the physical destruction of a complete PC grade device? I could not find anything in my go-to places (ISO, NIST, ISF).
I can understand the case of devices where the data is held in embedded areas not immediately identifiable - destroying everything is a solution to make sure no residual data could be left aside. This is not the case of that standard laptop.
EDIT: Following comments and answers, I would like to clarify that this company is a large, serious one. They know how computers works. They must have some SOP which dictate this, or the security officer on duty had a bad day.
I am not trying to guess why they have such a requirement but whether there is a case where this follows a standard.
