Yes. We all know this. Let's not argue over belief. If you want us to change something, few ways to do this. 1. clear facts (bench mark result of different configurations) 2. reference some authoritative documents. and patch always help. Really, I did not say putting swap at the edge of disk is a good thing. I was annoyed by calling this "stupid". Please do not call action of DD stupid even if they are. > Here is my desktop pc.

Please install debian-reference-en package from Sarge :-) Then you know what. http://www.debian.org/doc/manuals/debian-reference/reference.en.html Oh, please read install guide too. That has good amount of partitioning etc. too. http://www.debian.org/releases/stable/installmanual > You're a software developer writing in C?

(With my old 386, I used to compile my kernel or patched-X for a day, though.) Really, Linux or Windows, it is bad idea to fill actively used disk up to 98%. (For your case / partition. /boot may be OK since it is practically read-only.) For Linux, 90-95%, for windows 60-70% is my common sense usage. Cheers, Osamu PS: FYI None of these habits should be carried over to Linux and ext2. Linux native file systems do not need defragmentation under normal use and this includes any condition with at least 5% of free space on a disk. There is a defragmentation tool for ext2 called defrag, but users are cautioned against casual use. .....
