HDD and Bass
Hi everyone,
I am building a pc to fit into my VY. will be mounting it under the parcel shelf in the boot. I also have 2 12" subs in the boot. Just wondering if this will affect / damage the hard drive in my car pc?????
Is there some sort of material that I can wrap the hard disk in that will absorb the bass.

mine doesnt have any insulation at all, but its in glovebox, does fine, but id definately suggest something
you can get rubber spacers to screw the hdd to, other than that, im sure others could come up with some wild ideas for suspension. check out www.mp3car.com aswell.
I'd work with notebook drives as well if possible.. they are designed to be alot more shock tolerant.

if you have the space, get a 3.5 desktop drive, much better, thats what mine is. notebook hdd's are better for instant shocks every now and then, ie dropping the thing, and if you dont spend big money on a good brand one, they aint worth shit and will fail, and most have slow speeds.
get a 3.5, cheaper, more hdd space and with good suspension, more stable.
Not a valid input....
where all hdd will fail is the little buble of air that supports the internal disk....pop it...and it is all over red rover.

mouce...it's air......you won't see it. I'm going from what I have been told. Apparently it was an issue with early laptops. When they were on aircraft and pressure changed, it used to destroy the cushion effect provided by it.
I doubt that low frequencies would do that unless your in extreme circumstances.
This is something I have always held true as it was told to me by a IT engineer. I'd be very interested to know if this was not the case!
Would love to have something to rub in!

Most hdds are bearing mounted on a spindle spun by the motor.
The head arms move over the discs at a distance but heads themselves are within a micron or two from the disk. I imagine that they can take a little bit of a jolt without much issue and I would think that if the drive was mounted in the glovebox or maybe under the east etc vibrations shouldnt hurt it. if you want someting durable, go a old 20gig drive for the OS in the boot and run a usb extension lead down to the front for a storage drive. makes it a bit eaiser to take out when you want to hook it to the pc to load it up [ or just ethernet out the window / wireless link it to your home...
if anything modern drives need to have their pressures equalised which is why they have vent holes, beyond the hole is a tiny filterscreen to stop dust getting into the disk itself and yeah should be fine.
for mounting i wouls suggest mounting the drive either VERY firmly or hang it free-air from an old hddrack out of an old case.
you can tidy cables by going SATA if you want that extra touch.
hope it helps a bit

Actually, all HDD's (going all the way back to the trusty 42mb one I have in front of me at the moment, yes, I'm a geek) have vent holes. It was because of the amount of heat that built up in them that they needed to equalise pressure. Otherwise they'd crack the casing.
12v: I've never found ANY space for any sort of 'bubble', that's why I was asking. All of the drives I've pulled apart are bearing motors that sit on some sort of foam suspension. I don't know of any that used an air cushion as it would change pressure with the heat generated by the motor... I'd say that the IT guy was having you on.
Most modern HDD's are designed to take a 300+G shock, I doubt any Bass system would be able to deliver that, however laptop HDD's are more durable when it comes to constant shaking/vibration.

how close will it be to the magnets? I'ld be a bit worried about that if its close.
smooth moderator
haha, never put a computer near magnets they say, well, kinda hard, as the hard drives have strong magnets inside them anyway. its only really crt monitors you should keep away from magnets.
the hard drive will be fine near the subs.
yeah, i would go SATA, the cables can be longer making it easier to locate the drive in a convenient position.
All depends, it may cause damage while the hard drive is spinning as there is more change of the heads touching the spindles. This would be the only thing I would be concerned about.

all i can say is ive been running my hdd in my carpc setup for close to 12 months now, seagate 3.5" ide 200gb, full with music and apps and some movies, and not a problem yet. it sits in the glovebox all day, and only when outside temp hits around the high 30s does songs start to jump occasionally, but that could just be a shit mp3 file too. i have had it freeze maybe 5 times since i started using it.
that could also just be windows doing it's thing.

Hard drives are surprisingly versatile. I once had an old 450mb hdd that I thought I might mess around with. I gave it hell, dropped it from about 6 feet off the ground onto concrete, shook it around, threw it, and it survived! I was shocked of the amount of beating it could take. So in another words, it should be fine. They are fairly cheap anyways now so surely it wouldnt be the end of the world if it did happen to die.

The older drives (100mb to about 800mb) were fairly tough, because the way the data was stored on the platters inside the case, there was a lot of space on there that was 'empty' (not really, but for this argument let's say it is), so if the 'empty' space got crippled by the head scratching it, it could almost auto-recover itself.
Any old-school computer nerds here remember how crap the 850 and 851 meg HDDs were? The reason they were so crap is because that's when they changed the way the data was written onto the platter. It didn't have that failsafe mechanism in it, so once it was damaged, it was dead.
