What size torx screw driver to open a HDD

I have two crashed HDD that I like to open up and check out the plates

I presumed they are torx screws (star shaped). What size screw driver should I be buying. I have a 2.5 in and 3.5 inch HDD.

you dont open a hdd if dirt gets in there then its history, we talk 1 spec of dust here. these hdd we are talking old ones not ssd , they are assembled in a vaccume dust free lab.

both are dead HDD.

geek_ang_ck, Jun 14, 4:29 am

that is what is inside them.
if you open it its history . if you just want to see what yours looks like and your throwing it in the bin or use it not as a hardrive after you can open it bunnings should have the torx bits otherwise engeneers trde supply mitre 10
take your hdd with you so you get the correct bit for it since it is dead anyhow .

Good magnets in them though.

iirc its a T8 - might pay to double check though

ang_ck has made it pretty clear that they don't care, the HDD's are dead.

From memory it's the tiny little screwdriver you need. Don't know the exact size, but they are pretty generic.

geek_schizoid, Jun 14, 4:42 am

The most common sizes used in hard drives are T6 and T8.

i would tke the hdd in to the store always good to have a full set to open toasters and all sorts with full bit kit.

Was just gonna say - got mine from Bunnings

LOL, thanks again guys

geek_ang_ck, Jun 14, 5:54 am

That doesn't really give any details of the sizes though but I see this one.

Seagate & WD use Torx and Samsung standard Phillips or Frearson. As above, if you're wanting to strip one, you'll need a full set as the internals use different sizes. The platters make good coasters lol.

king1, you are amazing. thanks a million
Lostdude, platters as coasters, LOL, that will be so cool. I have a Samsung 2.5 in front of me, and it is a Torx screw.

geek_ang_ck, Jun 14, 10:01 am

True, haven't opened any 2.5" drives so maybe they only use phillips on 3.5? Dunno but yeah, I've got about 20 that I use as coasters for both home and at work lol. Funny thing is no matter the manufacturer, they're almost identical in size

geek_lostdude, Jun 14, 10:45 am

Bought it today. Accumulating coasters and fridge magnets this afternoon! Onto my third HDD now, and several more to go.

I bought this today


r.g.nixon, looks like you are enjoying it too. The coasters are fantastic.

thanks guys

The platter look more like made of glass.

geek_ang_ck, Jun 15, 4:36 am

From outter-most layer to inner-most layer, the composition of a 3.5" hard drive platter is as follows. 5 micron thick layer of cobalt, the magnetic data substrate. 20 micron thick layer of 90% nickel & 10% phosphorus, making the nickel non-magnetic (This layer is present because nickel takes a very high polish and cobalt (the outer-most layer) does not adhere well to the inner-most layer. The inner-most layer is comprised of 96% aluminium & 4% magnesium; Aluminium is cheap and lightweight, and magnesium strengthens aluminium.

geek_r.g.nixon, Jun 15, 4:38 am

2.5" ones are different. They do contain glass.

geek_r.g.nixon, Jun 15, 4:41 am

gosh, the 3.5" HDD has very strong magnets.

geek_ang_ck, Jun 15, 10:05 am

Neodymium http://en.wikipedia.org/wiki/Neodymium
Ouchies when two of them slam together on the tip of a finger!

There's a yellow and black set of torx and other screwdrivers at Hammer hardware for $10 in the $10 bin.
I use them and have taken apart almost 100 harddrives.

Don't buy the cellphone opening kit from the 2$ shop, the torx screws are rubbish.

Connect up some speaker cables to your hard drives reader arm and it will make music sounds.

geek_marte, Jun 19, 8:53 am

Just BTW, DO NOT put the magnets in your pocket with your ATM card. They are pretty effective at demagnetising them.

geek_ianab, Jun 19, 11:05 am

If the drive isn't functional, you can't really make it worse.

But it is totally possible to open a stuck drive, unstick the head, and close it again, to get it running in order to recover as much data as you can, without needing a clean room.
