Faulty logic board - how to erase hard drive

Hi there,

I have been told by an authorised service provider that the logic board in my 2016 MacBook has failed - it won’t recognise its internal hard drive when it boots up.

I am thinking about trying to sell it for spares / parts, but I’m concerned that all of my data and personal information is still stored on the hard drive. I am wondering if there is any way to erase the hard drive in its current state? I don’t believe I have Find my Mac activated on it.

I suspect not but thought I would ask...

thanks all!
