Ah... So as I suspected you didn't know enough about either Linux or
Windows to explain the difference.
However, your first reference doesn't discuss disk defragging.
In addition your second reference doesn't discuss disk defragging.
And, not only that, but your third reference doesn't discuss disk
defragging.
And finally, TA! DA!, your fourth reference discusses disk defraging.
I've had this feeling all along that you didn't really know very much
about computers and all this shouting and hand waving was really a
facade to disguise the fact. And you prove it.
You made the statement that de-fraging was necessary and I questioned
it, you, not knowing the answer ignored my question; I asked again,
with emphasis, and lo and behold, you went to google and discovered
some references but apparently, not only did you know anything about
the subject, but you didn't even read the references that you posted
as three of the four had no relationship to the subject.
You have certainly proved my original belief that you don't know what
you are talking about as even your final reference doesn't state that
defragging a Linux disk is never necessary.
So that you won't have to take the bother to actually read any of your
references I'll quote from your only valid reference:
NOTE: The "first filesystem" refers to Windows and the "second" refers
to Linux
--------------------------------------------------
The first filesystem tries to put all files as close to the start of
the hard drive as it can, thus it constantly fragments files when they
grow larger and there's no free space available.
The second scatters files all over the disk so there's plenty of free
space if the file's size changes. It can also re-arrange files
on-the-fly, since it has plenty of empty space to shuffle around.
Defragging the first type of filesystem is a more intensive process
and not really practical to run during normal use.
Fragmentation thus only becomes an issue on this latter type of system
when a disk is so full that there just aren't any gaps a large file
can be put into without splitting it up. So long as the disk is less
than about 80% full, this is unlikely to happen.
-----------------------------------------
If you had bothered to read what you referenced you would have seen
that the author states that a Linux disk will remain unfragmented
UNTIL ABOUT 80% OF THE DISK IS FILLED.
( although that is very dependant on the size of files being stored)
So, your assertion that Linux disks don't require defragging is
technically false although probably true, in practice, except in large
file servers.
However, that was not the point of the exercise. The point of the
exercise was to discover whether you really were as un-knowledgeable
about computers as had been suspected and you certainly removed any
doubt about the matter.
And you are lazy too. You didn't even read the references that you
provided.
You have the audacity to "help" people with their computers? Amazing!
It certainly says something about the gullibility of the people you
associate with, doesn't it?
