Hi Wendy, Diskeeper's good. I used to run it but I now use perfect disk. Do you ever do an offline defrag, or does background defragging do the trick? 

                    John.

I use Diskeeper from

www.diskeepereurope.com

This works away in the background defragging all the time, so you don't
have to worry about it.
I do wonder whether other things might be making computers run slow. I was recently recommended to change from AVG to Avast anti-virus, as Avast takes 
up much less memory and computer performance improves, but I found I could
not access the free home edition, as it didn't have a proper menu system
which JAWS could access, so I gave up on it and returned to AVG. I have AVG Pro, which is completely accessible in the normal way with alt taking you to 
the menus and normal use of cursors to get to what you want.

Wendy

Hi Dorothy, I think the best way I could explain a defrag is this. Imagine a
large group of children getting onto a bus. If the bus is empty they can all
sit together and where the teacher tells them. If though the bus is crowded 
the group is split up and can't go where the teacher wants them, and when
it's time for them to get off the teacher has to spend time looking for
them.
 Windows knows where it wants files to be on the disk, and has indexes of
their positions and their details, so it can find them when they're needed. If a file's fragmented into little pieces it takes windows time to find all the bits, and sometimes one of the bits gets lost, or windows can't find it 
in time, and then you get an error.
 A disk failure's a rotten experience. I've had a couple in my time, but I
don't think for a minute that defrag could have been to blame at all for it. 

A disk is hardware, and windows is software. Windows errors could cause a
software failure, but not a hardware failure.
I've had a situation where a virus destroys a disk, but I've only known it
once, and it may have just been coincidence that the disk failed at the same 

time, but it was certainly a nasty experience.
 I would hope that it hasn't totally put you off defragging. Without it
your computer's going to be in a total mess in no time.
                   John.

John I read with interest and hope andrew will read this 2 years ago  on
my
Desktop  Viglen Geni I did my first Defrag ever and with great care. The
following day I had a HD failure, now andrew suspected the 2 may be
connected and tried to explain about Indexes whirling around fast and
suppose I may have stopped a few seconds  too early I do not think I did
but
I did have the Hd failure it and its  repercussions,which were due to
Engineers making mistakes that are too awful to explain meant I ddeveloped 


a
Phobia about ever doing a Defrag. Ps I hope andrew doesnot read this but
this year I plucked up courage to do them again with  very great caution
leaving on for hours to be sure. So perhaps John you can explain about
these
things called Indexes whirling around the Pc so the rest can better
understand there risks Thanks Dorothy

Hi everybody, another couple of tips that will help your computer to keep
running as it should.
 Firstly don't let cookies build up. If left to bild up they will have an
effect on your computer's performance. Some of them can also be harmful.
 Secondly do a defrag once a day. The less fragmented you let windows get
the better. It's an obvious thing, but it's amazing how many times I've
heard of people never defragmenting and wondering why they have errors,
and
why their computer runs increasingly slower.
 Lastly for now SFC. If you get error messages it's a good idea to run
SFC,
just in case system files have been altered badly or corrupted.
 To do this, put your windows cd in the drive. Shut down the welcome
screen
when it appears. Go to start and then run, and type:
sfc /scannow
 You'll hear the cd power up. Windows will scan all its system files and
replace where necessary. Jaws still works during it, so don't be worried
about lack of speech feedback.
                   John.
