A guide to a noise free HDD using stuff you can find in every home. With some rubber and little patience you may turn a Raptor into a quiet baby.... :)

Every HDD makes some noise...Fact
But! This noise is in fact amplified as HDD touches the metal case of our PC.
So if between our case and the HDD is something else (see rubber strap from a tire inner tube) then the noise is deduced significantly!

Step 1: Materials Needed

The materials you need are:

Cross cuts from a tire's inner tube (or anything like a rubber strap)
and some screws.
If i did this I would pull the bands tight so it holds the HD tight and secure and you can still move the case
Wouldn't putting rubber on both sides of the computer case on the screw that mounts the HDD negate the vibrations traveling through the screw as long as its in tight but not too tight? Refer to picture.
i have a couple antec cases that havw rubbers in them for the hdd's, you have to use the special screws that came with the case though, they are of a different shape than normal screws
its a good idea but i think the rubber washer will be too dense to absorb some of the vibration. i did something similar to this but used surgical tubing and i strung it across and set the HD on top of it. i don't move my case when it is running and it is in a place that does not get kicked or bumped but to ensure the HD would stay put, i used some thin plastic ties and ran it in the screw hole of the drive and around the surgical tubing... it does not move at all, looks neat, does not sag much at all so you can stack the drives fairly closely together in the case, is cheap, and it very very quiet... it is very nice. liknus, Thanks for putting this up :-) WL
I forgot to mention the rubber was from an inner tube. Maybe then it will be less dense and absorb the vibrations better. And the rubber does not go through the holes. Thats why it has to be sorta tight to keep the screw from touching the metal of the case and transferring any vibrations. And friction holds the screw away from the metal.

well... they are ok but will not give the isolation hanging gives. actually i have a design for a mount not unlike engine mounts for the hard drive if only i could build rubber things! i can build just about anything with metal, wood, fiberglass, and electronics but i don't know about rubber or the like. i know it is possible because after all they are made out there. i just wish there was an easy way to cast rubber. maybe i will look it up sometime :-) cheers, WL
I used the replacement elastic you can buy to sow in your clothes, saw it by chance in a black version while shopping, it uses a compound they call 'elastodiene' defined as: A manufactured fibre composed of natural or synthetic polyisoprene, or composed of one or more dienes polymerised with or without one or more vinyl monomers, and which, when stretched to three times its original length and released, recovers rapidly and substantially to its initial length. And polysoprene is: The purified form of natural rubber is the chemical polyisoprene
You can readily buy silicon, usually used for mould making from companies like <a rel="nofollow" href="http://www.barnes.com.au/">http://www.barnes.com.au/</a> (An Australian company, but there are plenty more in the States). Can make darn near anything out of it.<br/>
Yes but since that's only a milimeter of rubber it only helps marginally, the longer rubber works so much better, the system you describe makes you go "I think it's a bit less now maybe" whereas hanging it from rubber makes you say "is it even on?" :)
There was a time HDs did employ that method in a fashion. I'm look at an older one. The "carrier" that combines the the disk portion with the PC board does mount rigidly to the case, but the disk portion mounts to the carrier as illustrated.
You can buy exactly this type of isolating mount but in silicon rubber, my Vantec P180 case at home comes with them, and the result is almost no disk noise. Having big fans running at slow revs also helps!
You do realize the majority of pc noise is from fans right?<br /> The HDD&nbsp;makes up a small amount of noise so this isn't really effective unless your pc has no fans because its low power or your pc is water cooled.<br />
If it is RaptorX at 10000 rpm then much of the noise comes from the hdd :) Believe me :P
Shouldn't the HDD be grounded simply by connecting power already? The molex connector has 5V, 12V and two ground connections.
Indeed it is.<br />
I came across this and was just wondering: What model of computer case is this? It looks similar to two of my computer cases, but it isn't identical to either... and not knowing is driving me nuts!<br />
what if your case doesn't store the HD like that?
The ground is not required, It is already included in the 4 pin molex connector connected to the HDD, in fact, there are 2 ground cables in it.
This is like what they had on lifehacker but cheaper.
Why ground the HDD? It will work without being grounded. Also, what kind of case is that?
Because grounding it prevents it from being shocked by static or when reaching in to move it for upgrades/repairs.
Obviously a HD is already grounded by the powerplug and the data cable's grounds, so it's a bit superfluous.
No hard drives should ever be moved while they're spinning (unless you LIKE head crashes). If you have a laptop, and you carry it around while it's running do yourself a favor; set the Control Panel, Power Options to stop the hard drive whenever you close the lid. Then, when you want to carry it around without Shutting Down, just close the lid to stop the drive. When you open the lid again, it springs back to life in 3 seconds. You'll never miss a beat. If you're moving your desktop around while it's running you're just asking for trouble. The section of your hard drive (read, 'your stuff') being vaporized might never be missed (perhaps it's the Help file for some little-used app on printing upside down or whatever) but if it's a critical file (like a Windows file) you'll wish you'd never moved the box. When you scrape a sector, it's gone. The only thing standing between the read head and the platter (spinning about 100 revs per second) is the cushion of air that's produced by the platter spinning. One small bump, and the air is not enough to prevent a head crash. If you get the chance, pop open the drive bay on any Panasonic ToughBook laptop. They have a gel barrier to protect the drive. Ordinary laptops are running barefoot. This instructable cushions against shock on a desktop, but why take the chance?
Apply pressure to the straps as you bolt them in, have 8 straps, four mounted to the top, four to the bottom (each exerting pressure)
I hate it when I'm not hep to your jive, but HDD stands for hhhard...drrrrivvve ...d...d...d...something??? Anyone? A little help, please. When I come to power, all acronyms will have to be spelled out at least once.
HDD stands for <strong>H</strong>ard <strong>D</strong>isk <strong>D</strong>rive<br/>
Ohhhhhh, thanks. I guess the classic term, "hard drive," in use for decades, was confusing.
I hope I don't reopen an old debate, but...<br/><br/>Actually, <em>HD</em> is a bit confusing now. The new version differentiates between a HDD (Hard Disk Drive) and SSD (Solid State Drive).<br/>
In the beginning I believed they where called Winchester drives
In the beginning they were called winchester because one of the first hard disk (IBM if I'm not wrong) has the same model number of a winchester gun, so the name !
Just don't plan on moving ur computer!
You could also use that rubbery mesh sheet that's marketed as a gripping layer for under carpets, and as drawer/shelf liners. It's cheap, and could cradle the hard drive without any problems. Not as good for heat conduction, as your method is.
I bought some shelf paper at the dollar store that may be perfect for your ides.It's made of basically the same sticky feeling rubbery stuff as those jar openers they used to sell. They may do your ABLE justice because they were like fishnet. And possibly thin enough to actually fit and allow you to anchor it with the screws also!
Very good ideal. Well put together Instructable. I tried the method that xtank5 suggested but modified it a bit. I didn't want to mount like the Instructable says, I move the computer around a lot but I did want it quiet. I used rubber from an inertube and cut it to fit to length of the HDD for both sides. I only put it on the inside of the HDD mount rack so that the screws ground it all. Works very well, it is much more quiet, I can't hear it over my case fan. For what I needed it is quiet enough for me.
in reply to fan question by mad english dude: all the fans are supposed to do is move certain volume of air in unit of time. same result can be achieved by smaller fan running at high speed or larger fan running at lower speed. higher fan speed means more noise...
mine already has rubber washers and my dvd drive...came like it
Hmmm... I should take apart my laptop again and see what noise isolation I can do... With double benefit of potentially giving it some crash protection in the event of a solid landing :p
anti vibration, shock resistance etc. is an engineering field in-itself. After reading an article in QST on the subject "I" would mess with the drives in a laptop. I might defeat any protection designed in by persons, who know more about it than I do. I think it reasonable to assume as a laptop is intended for portable use, the manufacture has taken steps to insure product durability.
I'm very much aware of that :) I'm also aware of the extra package I could have bought for my laptop to basically add a layer of foam and bubble wrap to my laptop's hard drive :p The default condition is hard mounted to the HD cover which is screwed into the chassis. <br/><br/>My sister's laptop, on the other hand, comes in a rubber sheath and floats on cantilever springs. That, obviously, shows a bit of engineering was put into place.<br/><br/>More modern laptops use accelerometers to quick shut down in the event of a crash - which is likely more effective than any impact isolation :p<br/><br/><hr/>So, I did some sound/shock proofing - and shortly after removed it as it compromised the cooling capacity of the drive. I'm working on a solution for that at the moment...<br/>
If you don't have the HD touching metal its always a good idea to add a ground strip from the HD to the case to discharge any static electricity generated by the rotating spindle motor. If you don't, static will discharge through the power cable or the IDE/SATA cable and thats not a good thing.
This is brilliant. I don't know, but it might mean the drive lasts longer - engine mountings for cars are basically the same as this. My next PC isn't going to have a hard disk (watch this space, instructable to follow), but if I get the chance I will definitely try it myself.
how does this work with hard drive lifetime? Could allowing greater motion increase the likelihood of a HDD crash?
Okay, hanging the drive with rubber will certainly be effective. They also use rubber suspension systems for microphones in recording studios and have since at least the &quot;crooner era.&quot;<br/><br/>But this system requires having a case with spare 5.25&quot; slots, which not all of us have -- I really like having two DVD drives as well as two HDDs in my Presario.<br/><br/>You can get effective isolation from vibration without moving your drives from their original slots with the careful application of much smaller pieces of rubber-like materials. <br/><br/>I used some really small o-rings around the mounting screws inside the drive cage, along with soft washers against the screw heads outside the cage. Don't tighten the screws too snugly ... the Presario used a slide-in system anyway so I had to leave some clearance. (And yes, I did have to &quot;improve&quot; the clearance a few millimeters by spreading the cage as I slid the HDD in. But only a little. Not new bend creased the cage.)<br/><br/>There are some really cheap commercial products that employ this concept. Check out this link:<br/><br/><a rel="nofollow" href="http://www.frozencpu.com/products/5203/scr-98/Hard_Disk_Drive_Anti-Vibration_Screws_-_4_Pack.html?tl=g7c113s569">http://www.frozencpu.com/products/5203/scr-98/Hard_Disk_Drive_Anti-Vibration_Screws_-_4_Pack.html?tl=g7c113s569</a><br/><br/>These silicone-damped screws are only $1.49 for four, plus shipping of course.<br/><br/>Frozen CPU has a variety of cooling, noise dampening and case modding products and gave me good service, as well.<br/><br/>I'm sure there are a number of ways to create small &quot;washers&quot; from innertubes or similar materials to damp vibrations around mounting screws. I bet a set of hole punches would be quite helpful. <br/><br/>The resulting little washers could also be applied to fan mounting screws as well.<br/><br/>Maybe these direct-mounted dampeners would not be quite as effective as the suspended system described in this Instructable, but you could haul the case around without worrying about the HDD slamming into its enclosure.<br/>
does this spin out of control like a helicopter?
Hmmm, does the drive suffer at all from any movement that may result from being suspended with the platters spinning away inside? I only ask this as the other day I had my MP3 player (with a HDD) freely suspended from the top of my tent and it started trying to move around in circles. I was wondering what was happening until I realised that it was because of the hard drive spinning inside.
I was curious if the rotational forces from the spinning platters, combined with the bit of free play from the rubber mounts, would be enough to unbalance the drive and cause errors due to the precision being off... Probably not, since the platters are attached to the spindle which in turn is usually molded into the drive housing (so everything moves together), but it's something to think about. -darc P.S. Phooey on Statics and Dynamics : )
haha thats really funny
BY adding yet another fan , does that not defeat the purpose ? fans are my problem ive renewed all but still sounds like a server room.how can we silence fans and he air extracter please keith
I've seen this before, but this is better than rubber bands.Very nice.A sheet of 1/8" to 1/4" thick aluminum top and bottom will be a good heatsink.Don't cover the "Breathing Hole" of the HDD. You could glue the Aluminum on using Arctic Silver Adhesive. Sorbethane is a great insulator of sound, also neoprene.Make straps of that. Quieting fans ....run two in series(electrically)...slower fans make less noise,and if they're both blowing the same way (one in, one out) the airflow will be about the same.
