1. Scandisk is dependent on what filesystem you're using. If you don't know, you're most probably using ext2 or ext3, which uses fsck.ext2. Defrag isn't necessary for most Linux filesystems, since they retain their performance even without it.
2. Check out /etc/fstab. For more info, see fstab(5).
3. Use a text editor. There are oh so many. Common simple ones are joe, pico, nano, etc. The two complex giants are vi and emacs. I'm going with emacs.

Make sure you run fsck on unmounted drives or bad things will happen.

[Dolda2000]

It usually warns about that, though.

[genlee]

Yes it does and i know a few people who ignored the warning and broke the filesystem.

[Dolda2000]

Yeah, I guess you're right... I guess many here have seen the warning machinery that MPlayer has to make _absolutely_ sure that noone compiles it with gcc 2.96? I bet there are people who do it anyway and complains on the mailing list that it doesn't work.
