The 2.5" disk in my Samsung laptop comes wrapped in an aluminum foil envelope. There is also a piece of aluminum over the memory modules. I replaced the disk with an OCZ Vertex SSD, but I didn’t reuse the aluminum pocket because the SSD seems to have an aluminum case of it’s own.

What is the purpose of the aluminum wrapper?
- Heat dissipation for the disk?
- Anti-static protection?
- EMI/RFI protection from interference caused by nearby components inside the laptop?
- Noise/vibration suppression?
- Airport x-ray machines?

Here's what it looks like:

From the small indents in the aluminum foil it looks like it maybe protecting components that where directly under the drive.
But in all honesty im just guessing, is it padded ?

Could also be a heat shield to protect the HDD controller from whatever the HDD was crammed up against.

The photo is not mine, I found it while googling and linked it. My disk is completely wrapped in aluminum foil and the mounting screws hold the foil in place.

Completely wrapped implies there were issues with EMI.
