Maxim really has a bad attitude, but I'll try once more, and only once. This post I quote from Willie Wong has an step-by-step guide that Maxim obviously didn't read, because even the most utterly illiterate person would understand it.

That the reason why (iii) and > (iii') differ is actually (i). What Maxim fails to see is that fsck *is not a fix* for his problem. The real problem is that the fs is marked dirty, and that happens because it has not been unmounted the right way on shutdown. When fsck runs at boot time, the fs is marked clean and it can be mounted, when fsck doesn't run it isn't marked clean, and, hence, it can't be mounted. Please, Maxim, once and for all, understand that running fsck when the power is low is bad, it could completely break your fs, do you really think that's an acceptable policy???? Please, Maxim, once and for all, understand that if an fs is marked as non-clean, it can't be mounted, because it could completely break your fs, and you would lose all your data in a single sweep, is that an acceptable policy??? Plese, Maxim, once and for all, understand that the real problem is *why is your fs being marked dirty*??? That's the problem that you don't seem to be aware of, you are now just feeling a rigid zealotry for your cause and you are not even listening any longer. Please, read this post, quotes fron Wong included, and try to understand what we are saying before even responding. You are only repeating yourself "but with the powercord it works, explain me why?", and we have done so many times already: with your power cord, fsck works, when fsck works, the fs is marked clean, when it's clean it can be mounted. Right? Now ask yourself: why is not not clean? Why??? To explain your crazy theories you have invented some rules that never existed, during more than 15 years of ext2, it NEVER ever required fsck to boot, that's an invention of you. Others have already told you that fsck DOESN'T run at every boot. Only when the fs is not clean or when it's due. They even told you that the tune2fs tool can be used to control this, and that fstab can as well. You didn't even bother to check the man pages, instead you just continue to invent theories that can support your crazy idea that the Earth is flat so everything can fit together in your mind. If you want help, we are handing it to you, if not, please, just stop and good luck anywhere else. Regards, and some tea. -- Jesús Guerrero
