DiskClick: Ever wanted to hear old hard drive sounds

Hearing the drives has been really nice actually, and got me noticing all kinds of interesting and sometimes unexpected behavior going on with my system, and actually helped find a bug with my terminal multiplexer.
With 64GB of RAM my entire home directory fits, so only writes go to the drives, and it's been surprisingly performant for my workloads.
This kind of intuition goes back a long time, too. Levy's "Hackers" describes the MIT TX-0 having a CPU register connected a speaker and the hackers who programmed the machine being able to suss out how their program was doing by the sounds the machine was making. Indeed, that's closer to the "metal" of the machine than disk activity sounds.
The closest thing we have today are the fans throttling-up like jet engines, but by the time that happens things have usually gone well and truly off the rails and it's just an indication of "all hell is breaking loose w/ your CPU".
So the major task will be drinking from the waterhose and having something useful fall out on the other side.
The drive mechanism sounds were they just louder back then or? You can put a HDD in a PC and it won't make the same grinding noises the old ones used to
OpenZFS works fine, but it can be tricky to install due to the license thing, not all distributions support it in their installer.
Bcachefs is said to be the up and coming contender for both, but it was merged to the mainline kernel in January, so probably at the moment it is tricky to install as well. I would think many of this year's distribution releases will make it available.
For all the talk about the raid5/6 issues on btrfs, people don't seem motivated enough to actually spend time fixing this. It's almost as if mdadm was enough and there wasn't that much drive to make it happen.
> And what is the next fs after zfs and btrfs?
I do something like this, https://kb.synology.com/en-us/DSM/tutorial/What_was_the_RAID...
Basically, mdadm, then on top, format with BTRFS
RAID 1 or 0 is just as a good idea as ever.
The 3x20TB btrfs setup I mentioned is configured with RAID1C3 for metadata, and RAID1 for data, and works just fine with even or odd number of drives.
It's funny how people assumed RAID5 when they saw 3 drives.
I switched to this after years of running on ZFS, and for my workloads btrfs is faster on Linux (not to mention the licensing/packaging mess).
These eclectic sounds are for a certain types of individuals and there is no quantifiable commercial value for search engine juice.
Thank you for the audio.
I assume you could in theory? While in reality, there's probably no way for user software to access that part of the hardware directly?
If Apple wasn't keen on it, they would limit the macOS taptic engine APIs similar to how they do on watchOS.
Your iPhone doesn't break from buzzing for an hour straight, developers are free to call the apis as much as they like. The taptic engines in both of the devices are pretty much the same thing, no?
Although, mildly related to your point: There was a Tesla software update last year that put a cooldown on the steppers moving the seats if the user fucks around with a seat position too much. Apparently _those_ were prone to overheat and brake.
We have no haptic permissions so far :D
I've got a NAS with five HDDs on my desk right now, you bet I can feel that when it goes thrashing.
I actually had a so-called expert who was brought in by someone else insist that my system be run on spinning disks because no SSD was reliable. Nevermind that I had carefully specified an Intel Extreme or whatever that was known to be reliable at the time (he had never heard of it).
Those things were fragile! All your data! A week of defraging and praying
The year was the early 2000s and the early years of my career. One fine morning, as I started up the work PC, it did its routine, including the HDD sound. I’m going to guess that sound was not the typical sound because that was the day the 2GB HDD (my guestimate, or it should be close to that size) decided to die on me, never to wake up again.
I went from the usual computer repair services to a few people’s homes who had advertised that they could “repair crashed hard drives” but failed. I remember the Bombay heat, the sweaty and frustrating walk asking for addresses in Lokhanwala, Andheri West, Bombay.
That took down all of my work and is one thing I will never forget. That taught me to have backups, and I didn’t break a sweat when a similar one happened in 2005. It wasn’t enjoyable, but I had pretty much everything backed up.
Yes, there is indeed a sound as lovely as it is, but a dreadful one that you will remember. Be careful.
There were some hard drives which you shall have placed in a fridge and then, before they get hot, had some chance to recover some data.
With Fireball, i think, the only option was to find another drive with good electronics, of the same size, because the motor controller was destroyed.
