Winchester Hard Drive Noises

Postby cjr8bs » Sat Jul 22, 2017 5:18 am

Having just recreated a working disc image of the long dead 8BS Winny, I am dead chuffed. I was getting to think, has anyone recorded or if not, could someone please record the sound of a Winchester Hard Drive in action? I would like to put it in to the 8BS sound archives.

Or was it just mine that sounded like an aircraft taking off?

I don't think I have anything of the right vintage but you raise an interesting point about the noise.

As far as I know there was a change of head actuator technology in the second half of the 1980s. The earlier type of actuator, which was present in some 20Mb disks we had at work at the time, used a stepper motor just like a floppy but obviously smaller steps and a much faster stepping rate which gave a noise a bit like a floppy stepping but quieter and much higher pitched. That was replaced by "voice coil" technology where there were no discrete steps because the base of the head arm was simply being attracted to one of two electromagnets and the controller would read from one of the platter to work out when it had gone far enough rather than counting steps. From comments I heard the first implementation used a dedicated servo surface, which explains why it was used mainly on large multi-platter discs, whereas later ones can read the embedded IDs. The "voice coil" drivers replaced the "whirr" of the previous drives with a "click" as the head moved.

Are there still any working Winchesters in hands like ours??

You may have to do a Radiophonic Workshop and recreate.

I have a working Winchester drive but the actual MFM drive in it has been replaced with a more modern 3,5" version (I think from the early nineties). I'll be happy to record the sound if no one else with an original drive reports.

What sound(s) do you need? Off-On start-up? Disk access? Idle operation?

I always thought the Miniscribe 8425 had the best sounds, but I don't have one handy.

Possibly the best hard drive noise video I've seen: https://www.youtube.com/watch?v=Y3b7yV4CUaw

<helpful type="still not">
So when I was at school we had a computing lab with a network of Masters with a Winchester file server in a cupboard --- probably a L3 with a 30MB Winchester. I eventually ended up using over half of it for my programs, by which I mean crap. Eventually the system died when it got struck by lightning and I lost all my stuff. Not bitter at all about that.

The Winchester had a fault. I believe what happened is that the sealed bearing for the platter had failed, and as a result it screeched, constantly, loadly, inside the soundproof cupboard but still. So if you just used an MP3 of aggravating metallic screaming, you would at least be technically correct (which is the best kind of correct)...
