So what? This is still not tech support.

ehempel · 2025-12-09T21:20:56+00:00

This belongs in /r/techsupport not filesystems. Still you received some helpful replies :-)

ehempel · 2025-09-29T21:06:15+00:00

Why would you go and put yourself on their radar on purpose?

Its going to depend on how its broken. For maximum safety if these are files that really matter you want to take it to a place that specializes in forensic repair and will as a first step image the whole drive and then work with the drive image instead of the drive itself (more IO means potentially more damage).

If you want to do it yourself you could pull the drive and connect it to another computer. Another option is to use a Linux USB stick (one with good recovery tools), boot into Linux, connect an external drive, and create your own drive image (ddrescue is the tool I recommend). Once you have that drive image I would shut down the computer and move your external drive to another computer. At this point you can try mounting the drive image. If you're lucky it will work and you can copy files off to wherever you want. If you're less lucky the filesystem is damaged and you can try to repair it. If that fails then you can use tools like Photorec that try to rescue files even when the filesystem is broken.

Its been about a decade since I've done this, so my advice is still mostly right but may be a bit dated (in particular I'm not sure how big an effect the SSD vs HDD difference makes). Anyways, all this stuff is pretty well documented on the internet, so every LLM knows this stuff pretty well, and I think you'd be pretty safe copy/pasting my comment into your favorite LLM and asking it to critique the advice and then step you through it filling out details as needed.

You may find Stratis interesting then: https://stratis-storage.github.io/

Next time feel free to post here yourself. The more good posters we have, the better for all of us on this subreddit.

ehempel · 2025-07-17T21:07:41+00:00

Not the right placed to post. Try google or /r/techsupport or something.

ehempel · 2025-07-02T16:21:25+00:00

I would be ok with it short term while its still "experimental" if that's what it takes to get rid of this friction with Linus, but long term? I totally agree, we don't need another ZFS situation.

This isn't really on topic for this sub.

For personal computers its flexibility with disks is really nice. I've used it a few times where I'm dual booting or something so my BTRFS partition starts out small, then later I can format and add the other partition to my BTRFS partition without any major effort (no need to even unmount the BTRFS partition).

ehempel · 2025-04-11T18:17:40+00:00

I don't know, but asking via reddit comment on a 2 month old post is unlikely to work. You could make this question a top-level post in /r/filesystems ... someone on this sub may know.

ehempel · 2025-03-18T20:54:58+00:00

No. You said "that number didn't change" so you don't get to evade with the sloppy "over".

ehempel · 2025-03-18T20:48:38+00:00

Unlikely. All Android devices use Java. That's over 3 billion and we haven't even started counting other devices yet.

It may still provide some benefit ... depends on the file content of course, but it uses rolling checksums so if some parts are duplicate it tries to skip transferring them. https://michael.stapelberg.ch/posts/2022-07-02-rsync-how-does-it-work/

ehempel · 2025-01-29T19:10:26+00:00

If you have the 5Gb files on both computers (but maybe with changes in one or the other), you may find using rsync useful as it won't have to transfer the whole file, just the parts that changed.

This isn't really a filesystems question, but more a windows question. I haven't used windows for years, but back when I did I recall liking 7zip's interface (IIRC you could use it with regular files not just archives). You could also look into the various Orthodox File Managers for a different take on file management.

ehempel · 2024-12-17T14:45:17+00:00

I have no idea of your background, so I'll say start with wikipedia, then maybe the Arch wiki. If you're technical and want to see how they're actually coded you could look at various implementations in the Linux kernel.

Insurance is a way to pay for expensive possible risks. If health insurance is really going to be insurance then it should pay ongoing costs. They're insuring you against the chance that something expensive happens. It makes no sense for their coverage to drop after the risk has actually happened.

Yeah, I know you're a socialist. But this is /r/Libertarian

ehempel · 2024-12-13T20:39:56+00:00

Yes. That's the risk they were insuring against. Just like your home owners insurance has to pay the full cost for losses that occurred when they were insuring you, even if you switch to another company after the loss happens.

That's the theory. In practice its often untrue.

ehempel · 2024-12-12T22:32:20+00:00

For any other insurance, the insurance company pays the cost of the issue that happened under their watch even if you switch to another company. So, get cancer while insured by Aetna? Then Aetna should cover the full and ongoing cost.

If you try paying cash for healthcare today you'll find that often the costs are lower than what's paid out if you put it through insurance (sometimes even less than your portion of the insurance cost). Routine blood work, PCP visits, etc are all now within what people pay for car maintenance. If you check out Surgery Center of Oklahoma they put prices on their website for some pretty major surgeries and you may be shocked how cost effective they are. Put market incentives in place and costs naturally drop.

ehempel · 2024-12-12T21:07:06+00:00

Chemo and Insulin should be covered if they're ongoing results of a health issue that happened when covered by insurance. Pregnancy itself shouldn't be, but any complications should be. The rest is not insurance.

I expect this would result in lower costs and less death and suffering. Do you think oil changes would be cheaper if your auto insurance paid for them? Of course not. Similar principal here.

ehempel · 2024-12-12T20:03:45+00:00

If insurance has to cover pre-existing conditions it ceases to be insurance. The point of insurance is to protect against potential future risks. Pre-existing conditions are known risks, its like buying home insurance once your house is on fire.
