I'm replacing the hard drive in an old(ish) Compaq Presario 2700. The old
hard drive has a silver sheet stuck on the underneath (circuit board side).
Do I need to transfer this to the new drive? What's it for?

Thanks. :-)

Probably not. It is probably a cheap RF (radio frequency) shield used
just to pass the FCC RF standards. And if your laptop works and you can
still listen to your favorite radio and TV stations, I wouldn't worry
about it. Although your neighbors might if they are say within 6 feet
away from it.

No.

It could be for EMI shielding, but it could also just be an insulator to
prevent the circuit board from being shorted out (even though it looks
silver, it's not conductive on the side that actually is in contact with
the circuit board). While you may not need THAT sheet, the circuit
board side of drives normally is exposed, and there may be a need for an
insulating sheet, depending on the installation.

Thanks for the replies. So should I just transfer it and be done with it?

Yes unless there's a good reason not to (like removing it will damage
the old drive).

Nope, it won't, it's only sticky round the edge.
