Hi All,
I have an upcoming appointment with a customer
who wants a number of his old computers
(mostly iMacs) removed from service.
With other computers, if I can remove the
drives, I just remove them and give them
to the customer to hit with a hammer.
But iMacs I will need a glass puller, etc..
So what I usually do when I can not get the
drive out is to boot into a Linux (Fedora)
Live USB and run
# dd if=/dev/zero of=/dev/sd[x]
An old iMac has been running this (x=a) for over 12 hours here using
thr “rescue” option from an old linux installer CD. I’ve done this with
newer Macs, but just left it running overnight, so not sure how long it took.
