You probably aren't waiting long enough. I'd wait ten (10) minutes before
doing a BHR (Big Hairy Reset).

I guess my question is why pushing power button causes this random writes ??
This is so happened that some of the kernel header files are corrupted (some
junk characters in a header file) and could not compile a kernel module ...


Erm? Uh? Duh?

You have unwritten system buffers in memory.
The system decides to write them out.
The system issues a command to the disc drive to write.
The disc starts writing, and you pull power to the disc.
What happens after that is anyone's guess.

In fact, just pulling power to the disc like that can
cause it to get confused and do a write, even if
it hasn't been commanded.

That's why a shutdown is necessary.

I know I need to do proper shutdown.

Then why don't you?

What if this happens? How do I protect this ... ?



DON'T DO THAT!

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
