How do you defragment the swap and the MBR? Also the registry isn't
defragged I don't believe when you defragment your drive. I know the swap
and MBR isn't. Are there any undocumented commands that do this. I have
media center and x64.

you only defrag the HD. The swap file is on the drive as is the MBR.
 
To be precise, you actually only defrag "partitions" on the HD. The swap
file is just another file within a given partition (the one containing the
OS), so by extension, defragging the partition which contains it, defrags
the swap file. However, you normally need a boot-time defragging utility to
defrag such a file since the file remains "in-use" during defragging under
the active OS. The MBR (Master Boot Record) is not a partition, not even a
file, it's a specific area on the HD which contains information about where
those partitions are located, and which is the active partition (i.e.,
bootable), if any. Thus, the idea of "defragging the MBR" doesn't even make
sense.

This is what I've heard concerning win98. The swap file you need at the
beginning of the drive. Since the pager is in use and swapping to and from
the swap you rename win386.swp and defrag. Of course windows creates a swap
file somewhere else on the filesystem of than the beginning. Then after
defragging delete that new swap and rename the old swap back to win386.swp.
I've notice a real difference by doing this. I seem to get better
performance. But that's 98. I don't know about xp.

You dont need third party software for that.Simply open system,advanced,
performance,page file,uncheck the box for C: Then close out,run CHK disk

Sorry but that's rubbish.

The amount of free space is very important when running Disk
Defragmenter. A
minimum of 15% is required but sometimes 20% is desirable if the drive /
partition
contains one or more large files. You can run Disk Defragmenter a second
and third
time if files are still fragmented after the first run. You can put
files more prone to
fragment in their own partitions.

If you use Outlook Express regularly compacting Outlook Express before
running
Disk Defragmenter is helpful.

Disk Defragmenter provides a "Most fragmented files" list. When a
fragmented file is
larger than the largest pocket of free space available then the files is
not fragmented.
Running Disk Defragmenter a second or third time does move files around
and can
reduce / eliminate the contents of the "Most fragmented files" list. The
more free
space on the drive / partition, the more likely it is that all fragments
will be
eliminated.

Free space cannot be defragmented with the Windows XP Disk Defragmenter.
Neither can your pagefile be defragmented because the file is in use
whilst
Disk Defragmenter is running. You can purchase other Defragmenting
Utilities e.g.
Perfect Disk, which will defragment your pagefile and free space.
Another option is to
place your pagefile in it's own partition. A pagefile partition is best
located as the first
partition on a second hard drive. You should leave a small page file at
the original
location.

The swap file is just another file within a given partition (the one
containing the OS).

The section you put in brackets may be true but in some situations is
not. You can have your pagefile in any partition on the same drive or
another hard drive, except you would be well advised not to place it on
an external drive. It is also best to retain a nominal pagefile where
the operating system is located. Where you have a page file in it's own
partition the first partition on a second hard drive is favoured.


Hope this helps.

As long as the second hard drive is on a different controller from the
system. It would still work, but the benefit is from enabling asychronious
read/writes.

Get a good third party tool that has features to defrag all these and its worth it because the automatic defragmenters are faster than the built in tool and besides have some nice scheduling features which will make regular defragmentation hardly a bother.

"but the benefit is from enabling asychronious read/writes".

Please elaborate as I know nothing about asychronious read/writes and I
suspect it is something I should know more about.
