Is it possible that ext2 has the same type of problems running defrag
programs that NT does?  The NTFS setup doesn't lend itself to simply
putting all the file at the top of the disk.  Access can be from anywhere
at any time so they use an advanced algorithm to decide where to put them
and, I think, they don't even try to rearrange the file placement after
they defrag the files.  I read their blub on the approached used, but my
Teflon brain (the original, non-stick surface) doesn't recall the
specifics.  There might not be an optimization program, as such, but a disk
analyzer would sure be nice.

I know fsck gives you an idea of fragmentation, but I don't know about
scanning for bad blocks. I'd be interested in this, as one of my
drives is having problems. Is there a program that can run on a
partition/drive (unmounted of course) that will scan & flag bad
sectors?  BTW, there is a 'defrag' program that I found, but it's
chock full of "warning: this might do really bad things, use at your
own risk" kinds of things.  It actually does go through and do like
that one Windows program where it rearranges the files. I haven't used
it (haven't needed to).
