Hi /g/ I just disassembled an old hard disk for fridge magnets

Screwdriver or bench vice, I always break them it seems.

>Screwdriver or bench vice, I always break them it seems.
I broke the last one of these I tried. I'd like to avoid that this time.

I did it... 4 tries, 4 broken mangmets :DDDD

use your credit card OP.

t-thanks anon

You don't
They're welded on or some shit

>They're welded on or some shit
Glued I believe.

>>57026538
Makes more sense that they're welded considered how they're positioned in a hard drive.

High heat unaligns magnetic domains. Welding would trash the magnets

This.

Which is also why you shouldn't just boil it to soften the glue.

I put a screwdriver between them and hit it with a hammer a few times. My one was glued so you could try with a heatgun and some slim metal peace, as well

That's probably worth a shot, if I can avoid shattering the magnet.

>>57026180
If it's glued on, acetone based nail polish remover might work

Welding is one thing but boiling water is not even close to the curie temperature. I wouldn't do it in a steel pot though for obvious reasons.

Fair enough. I can just soak it in a mug with boiling water for a bit I guess.

A combination of all of these worked.

I soaked it in a mug of boilling water for ten minutes, then put it in a little vice and tapped at it with the smallest screwdriver I could find. It moved after a bit.

I used the HD body as the hammer, which adds insult to injury I guess.

You guys are wimps I only used my hand to pull it out. That shit can pinch your skin and hurt hella though, be careful anon. The magnet is fun for throwing once at a metal surface to see it break and see all the magnetic dust clump. Also useful to hold loose screws together and being a fucking magnet.

Ignoring the rest of your nonsense, that's more or less what I plan to do with it. Put it on the bottom of a thin metal bowl and use it to hold screws while I'm working on things.

Just leave it

>Just leave it
I kept the backing plate so I can just leave it on if I want, it sticks magnetically very well, but it's more versatile this way if I want to do something else with it.

This. Soak it in acetone for a day or two. The glue will be weakened considerably after that.

>>57026451
no no no no no
a single card isnt strong enough, you need to stack them all together and use them all at the same time

none of you suggested bending the backplate?
bend the backplate, then screwdriver once the bending separates the backplate

>>57030843
>none of you suggested bending the backplate?
OP here, that's how I broke the first one of these I tried to separate. The glue is pretty strong and the magnet is much, much weaker than the backplate.

If heat ruins the magnets you could try submerging it in alcohol over night to loosen the glue.

>tfw just keep the backing plate on, wrapped the whole thing in masking tape, and use them as refrigerator magnets

>>57026180
been meaning to salvage some magnets, got two old suns with 20 HDDs each lol, might as well do something with them.

>>57031197
Alcohol won't work. It must be acetone.

I am also interested in this OP, I have a dying 1TB HDD that I might as well do this with.
