    Default HDD noises

    Having been a mechanic 40+ years and having had customers "sing" the sound effects that their cars made, this comes as somewhat of a mixed blessing.

    People have tried to explain the sound they think they hear in their systems and this site has some interesting .wav files of actual things that go "bump" in the inner workings of a tower.

    Just playing them for yourself will make your hair stand up..especially if you are some sorta tech-geek-type. I cried all through the slow spindle speed .wav.

    Maybe those types (above) should save a file of these sounds so they can be played to get a better diagnostic of the noise complaints that come here every once in a while.

    ...from the good guys at Hitachi Forums: http://www.hitachigst.com/hddt/knowt...c?OpenDocument

    ANY noises from the HDD are a bad sign. Except the super quiet little hum Seagates make. Which is so quiet the CPU fan will drown it out anyway to most peoples ears.

    Doesn't surprise me that Hitachi has a list.

    Actually I think Samsung makes the quietest drives.

    My Western Digital drives me nuts with the db level, but I like completely silent PC's.

    My PC's water cooled, and I did find a water cooled hard drive enclosure, but shipping it from Germany was outrageous.

    What about the clicking sound that's heard when the harddrive is actually doing something with data....?? surely that is not bad

    All my maxtors do it and I find it useful since the HDD light doesn't work for my sata drive, also have a couple of old seagate medalist harddrives that make a horrible racket, especially just after spin-up

    Clicking? They shouldn't do clicking. Maxtors are rattly sounding sort of when loading. I should amend my previous comment - MODERN Seagates are quiet.

    Used to be the IBMs with the glass platters but they don't exist anymore.

    You you're right, it does sound more rattly than clicky.

    Glass platters???? wouldn't the natural migration of glass over time (accelerated by the centrifugal force) cause the outer edges to become thicker and cause head scraping etc?? heat wouldn't help either...

    About Glass platters:


    This article appears in the Winter issue of ExtremeTech Magazine, which went on the newstands in January.

    When people think of personal computers, they almost always think of the CPU, or memory, or even graphics chips. They often forget that inside a PC is a purely mechanical device that spins at up to 15,000 revolutions per minute. In a more standard desktop hard drive, which spins at a tamer 7,200 RPM, a point close to the outer track is moving at roughly 48 miles per hour. In a typical working day, that means the outer edge of your hard drive has traveled 384 miles.

    But that's not the most amazing part. Each hard drive consists of one or more platters, called the substrate, typically made from very thin glass. We're not talking window glass here, but a precisely formulated glass or glass composite, which is highly polished and coated with a thin layer of magnetic material. The drive can record data on both sides of a platter by orienting magnetic domains within the material. One direction represents a digital 1, the other a 0. In modern high-capacity drives, Magnetic domain orientation is often vertical (pointing up or down).

    Though I don't think it's available here in New Zealand yet, I can't wait to check out the new SATA WD Raptor drive WITH A CLEAR TOP! (actually a clear lens)

    HDs make a lot of noise during (windows) maintenance.

    Chuga chuga brrrrrrrrrrrrrrrrrrrrrrrrr click click click.

    First time I ran the maintenance of some friends' comp for them they thought it was wrecking itself, or more to point - that I had caused it to wreck itself, so I had.........well you know what I mean.

    HDs in my experience make noises during reading and writing as well. Maybe it's because I've only dealt with comps that are at least five years old.
