<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I agree that running a disk defrag on a running Exchange store
is not the best idea. However, I think I need to clarify something.
Disk defrag and eseutil are serving two different purposes. Eseutil moves
data around inside the database file to make sure it is all contiguous IN the
file, and disk defrag makes sure that the sectors containing the files are all
contiguous ON the disk. As an Exchange database file grows, it can get
spread all over the disk just like any other file. Running eseutil for a
database on a fairly full disk actually has the potential to make the database
files significantly more fragmented, even if the data inside those files is
made more contiguous. Windows has to find a place to put those files when
it makes them or expands them, and that may mean filling gaps on the hard
drive. If the drive is dedicated to Exchange databases you are less likely
to find fragmented DBs, since the only thing on there will be DBs, but it is
still possible. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>A disk defrag will almost certainly not be able to defrag the
Exchange DB files while the DB is mounted, and if it could that could result in
a damaged DB. So if you want to run a disk defrag, I would suggest you
dismount the DB or stop the services. <o:p></o:p></span></p>

color:blue'>I would not try a defrag on a volume with the exchange store on it
while in production. The store is just a couple of large database files
and are not defragmentable except for what you mentioned, eseutil. As for
the other files, surely they are not causing performance problems for Exchange.</span><o:p></o:p></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:blue'>JKDefrag works well and I have used it on file servers and
workstations with success. Since it runs as a command-line utility it
works very well and is easy to schedule via the Task Scheduler.</span><o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:blue'>Defragmenting can help in situations where the drive is being used
to do lots of read/write access to the files stored on it like a File server but
since Exchange is like any other database system it houses it's files in
'containers' and therefore doesn't really benefit from the rest of the drive
being defragmented.</span><o:p></o:p></p>
