You say the sound comes from the power supply and the HDD is not plugged into the computer. My diagnistic: the power-supply makes a noise when it operates at very low load (almost 0mA of current), it is probaly making the cyclic noise because of some blinking LED or another very small variation of the loaf somewhere. This is a very common symptom of cheap power-supplies, but it doesn’t necessarly mean it isn’t working normally, just an annoyance.
I suppose, when you plug the HDD to the computer, it spins up and start drawing more current from the power-supply and the noise disapears. This is because the PSU has a buck-converter, the switching frequency increase proportionally with the current drawn by the load. When the current it almost 0mA, the switching frequency can be audible (electromagnetic forces can make some components vibrate, e.g: coils). When the current is nominal, the frequency will be ultrasound and you won’t hear it. I have observed this with many electronic devices. If you are worried, you can try another power-supply, after checking it has the same voltage and polarity on the plug, and can deliver at least as much current as the original one.
I’ve come across it once with a laptop power supply. I believe it correlated to a voltage issue of some sort. We just replaced it with a new one and the problems disappeared. It definitely wasn’t coil whine, but I didn’t believe the person complaining about it until I held it up to my head myself.
No, it’s nothing to worry about, it’ll be just a handful of super cheap parts in the power supply. Essentially when the power supply converts ac to dc, it has a bunch of standard parts, and if you cheap out on them, sometimes they make high pitched noises. The noises can vary in pitch too.
Can you record the sound? I’ve never heard of a power supply having any kind of noisemaker. It’s probably just electrical interference or coil whine or something, where the waveform happens to produce that periodic sound. (You might even look around and find a nearby device changing its power draw with the same periodicity.)
Haven’t been able to record it yet, but the sound only happens when the power supply is plugged into the HDD and the outlet (not one or the other), and the HDD is NOT plugged into the computer.
Plugging the HDD into the computer stops the sound. I was unplugging it from the PC to keep it offline when I didn’t need it. (After safely ejecting and waiting etc. of course)
I guess I’ll just need to unplug the power when I’m not using it, too.
Im most excited about the potential for crystal based storage. Right now there is work being done to etch silica glass internally, allowing for incredibly long term preservation and durability. It can even be rewritten, though the tech is definetly best for achival purposes and is being pursued primarily by movie companies wanting high quality storage.
DNA also sounds interesting, though it doesnt seem like a good way of preserving data long term. DNA is very fragile, and seems like an odd route to take for long term archiving.

Yeah the 5D quartz disk is very cool.
Anyways if you think about storage density DNA isn’t that “odd”. With DNA you can store dozens of copies of the data and parity checks in a very small space so even if some gets corrupted you can still get it. I get that organic stuff has its limits but the density is just mind blowing.
Density is defintly amazing in DNA, its just so fragile. Even our own bodies have a constant degridation of our DNA… I wonder if they could take that concept and make something sturdier by using slightly different molecules to make up the chains.
Maybe shorter chains with stronger cross bonding & a gentle method of reading the chain could also help?
Its definetly an interesting route & itll be cool to see what happens with it over the next 10-15 years.
There’s no authoritative list of instances since federation isn’t required, but tools like lemmyverse.net will give you a solid list of the ones discoverable from the most well known federations.
sounds like your main limitation is attaching the drives – if you can attach them all to a single system (ex. a separate computer or a NAS case) then at least it becomes somewhat easier to access them all at once
I was thinking JBOD but Wikipedia points out the same issue you mention with RAID 0, failure of one drive can mess up the logical volume which leads to a whole host of new issues to deal with during recovery
Not that big of a deal when it is a backup. Raid is not a backup solution, it is a 24/7 uptime solution. If the main drive dies with JBOD, then you have the backup. If a backup drive fails, then you still have the main. Trick is to ensure any drive issues are dealt with immediately and no backup runs if there is a smart error or similar on any drive.
So having software that monitors drive health and email/notifies you is necessary.
Secondary benefit of JBOD is all drives in a pool are still readable separately.
According to this you can copy stuff onto it. I assume you’ve tried to see if you can copy off? If not, then there is probably no way to extract the audio, short of recording it as it plays.
This helped me, thank you so much! I filtered by .mp3 and I’m using DownThemAll to download all the episodes in batches.
ETA at first, all the downloads failed because I was attempting to download multiple files simultaneously. After configuring DownThemAll to allow only one simultaneous download, it’s been smooth sailing.
The Playapod website mentions a web player, does the web player happen to sync with your app on the phone? If so maybe you can extract it through the web player on a desktop.
I’m sure plenty will disagree with me, but unless you have specific needs, I’d suggest spending more time sourcing your media rather than rely on transcoding. Most formats of popular stuff are available and Jellyfin will happily play it natively.
Also be aware that transcoding is VERY cpu intensive, unless you have a compatible gpu/transcoder. I run a ML110 with a 6-core Xeon (12 threads) and if Jellyfin needs to transcode something, it uses all of that and still stutters badly when seeking.
If you do need to transcode because you can’t source the media in a compatible way - you may want to use something like Tdarr to transcode it before you try to play it, so it’s ready when you are.
What if the cloud server corrupts your data in transfer or worse shuts down its server without notification. It can and has happened.
For example, I had a cloud backup went to get it and the server could no longer be found. That was with Dropbox mind you. I lost 10gb of important files because of it. Never trust just one source of backup. Always have a secondary just in case.
A mirror array is not a backup. So therefor I would use at least one of those extra drives for a weekly backup of your data. You want some sort of not real-time backup in case you get cryptoed for example
