Another great one. Thanks.

OK, let's be clear about that. The OS is not important stuff. The OS is
the easiest thing to get if you lose a hard disk. Some config files are
important, but neither the OS nor the software. Except if you write the
software yourself, but you doesn't. So, some config files are important
to manage carefully, not the OS. You find the latest version of your OS
if you need.

I don't know if anyone here believes that: I don't. There is nothing like
that in the logs of a desktop computer. I never heard of something like
that on servers and it would be useless and too difficult to put in
place for its benefit. And, by the way, when you are talking about the
speed of a hard drive, you have to say if it's write speed or read sped.

So, I'm pretty sure you read something you didn't understood and you try
to impress some political readers lost here with no technical knowledge.
So, take that sentence, give it a good form, and put it in your body
where it will grant you the most pleasure you can get with it. But here,
it's just a good joke.

OK, you repeatedly say you are involved in everything, including music,
and you can't get with inferior things on your computer. So get your mp3
garbage out of your messages. It shows you know nothing about good
quality sound.

That I can believe. You just invented everything, so you couldn't saw it
before.

That is something that happens. A hard drive has a short expected life.
Let say between five and ten years as you refuse SSD. So I can believe
you have already seen crashed hard drives.

That's something you never said here (at least I never saw it). It
means, you are copying all of your hard drive each time you are updating
your OS/softwares, installing something, are downloading something. You
can note I don't speak about creating a new file or updating it because
it's well beyond your abilities. It looks you take more time to save
your system than to use it. With the time it takes you to update it
compiling everything, you have even less time, than I was expecting, to
use your computer.

> What I want to know is what are the symptoms of an HDD
> failure?

That means nothing. A hard drive can fail in a lot of ways. And when you
have some issues, depending on the place it's happening, the symptom
will be different. For example, if you have a default sector which make
your file useless, the symptom is not the same if your file is a mp3
garbage or a file used during boot time. So the only way to know about
it is not to look for a hypothetical nonsense speed on your logs, but to
look at the number of default sectors.

I'll tel you a secret to manage your HDD: "man smartctl" is your friend.
If you don't have it, install it.

Once again, I don't believe your numbers. It's way more difficult than
that to know the speed of a hard drive. It depends if you have a lot of
little files or a big file. And the speed of read and write file are
different. And you have to take care of the cache, too.

> Is this this the behavior of a dying HDD?

In your head, maybe, I'm not in your head. In a real world, I don't
know, you didn't gave the behavior of a hard drive, you gave numbers
coming from your head.

Once again, that means nothing. Nobody can investigate with that. Mind
you: I wouldn't investigate for you even with the real data. But I'm not
the only one here and you don't give enough information to know what's
happening.

> C'mon lackeys, cough up some advice.

Why? It's your computer. It's your hard drive. I don't care if you can't
use it anymore.

> Or does your distro do it all for you including wiping
> your shit besotted ass?

The facts are: I can investigate and fix my computer issues, I can't
investigate issues when you don't give enough information, I don't want
to help you when you'll pretend later my help never existed.

So, take care of your issues by yourself. I don't give a damn if you
succeed or not. Good luck with that.

> Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha!

I'm laughing at your issue, but I don't understand why you are laughing
at your own issue. I have only two explanations, each one would be
adequate:
- you just invented everything and you believe you will impress anyone
  here with your fake story and your fake numbers.
- you believe anyone here would be annoyed to be unable to help you. But
  the fact is, except for your pet dog the terrorist, everyone here is
  happy to see you having issues with your computer.
