How to read from SATA HDD (AHCI) on low level?

[FusT]

I'm amazed by the amount of people coming to this forum because they copy/pasted some random sh*t code and then expect us to spoon-feed them the information they need (or worse, (re)write code for them).
What has happened to learning things on your own?
Yes, you'll make mistakes but you will learn from them.
Don't expect there to be a library/default implementation for anything, read specification/documentation and write it all yourself. It's the only way to truly understand what you're doing.

You clearly don't get the point. Why is there code on the Wiki if it doesn't work? What's the point of that?
Obviously everyone understands that to read from a hard drive you're supposed to give it the sector to read from and where is it supposed to be read. And even that would be a lot easier to understand from a verbal description rather than that piece of code which simply can't be made to work.
Anyways, copy-pasting has always been the most efficient way to do programming.

You have been a very well-disguised troll, touché

It's literally the first rule of programming. If it can be copied from somewhere, then that's the way to do it. Re-inventing is stupid and generally doesn't lead to be a better solution

If you literally mean that, any form for real programming, any form for OS development is not for you and never will be. To me it sounds like you don't even know the basics of programming, which makes sense if you've built your knowledge from google+stackoverflow copy-pasting. Maybe you should reconsider your career, it doesn't really sound like you have any interest in coding in general. Can i ask why you even went into programming in the first place? Bored?

Of course. You're asking as if there were another reason to start programming.
I don't really want to be a programmer, it's not particularly interesting, I just don't have better things to do.

I'm sorry, but my personal opinion is you should give up OS development. OS development requires a lot of motivation and interest, and first of all curiosity, and it requires a hell of a lot of discipline. There is no way around that. You've gotten into programming for the wrong reasons, and if you don't have the interest, you don't go and try to code one of the most complex things you can do in programming. It's not easy, and we re-invent the wheel all the time in effort to do it better or just do it in our own way for our own enjoyment.

Cool, it's important to have an opinion. It's also important not to take things you do for fun too seriously.

Don't we all do that from time to time? :p

This just keeps getting better and better .
So you're saying that because you're bored you're going to take up something you have absolutely zero interest in. Genius.

Touché aussi

I agree, he's a troll. A clever one.

Early April Fools'?
Let me see: a random persons that doesn't want to be a programmer, walks into an operating system development forum, wanting to do stuff, not by himself, just because he doesn't want to do any of those, because he is bored... What the hell?!

You can't just expect that things will work randomly. If you want to read from your hard drive, you MUST understand how it works, how you access the information, how much of that information you get per each read, what standards you want to use, how those standards work, raw reading or a file system... Hard work is how you do it. Take yourself some time, READ the documentation, TRY TO UNDERSTAND the documentation. This is not an easy topic, you should start with something easier. Try ATA PIO mode. If you didn't want to be a programmer then why did you come in here? Did you read: http://wiki.osdev.org/Required_Knowledge - http://wiki.osdev.org/Beginner_Mistakes

Guess what, it wasn't that difficult after all!
