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?

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 takesup 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 systemwhich 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 tothe menus and normal use of cursors to get to what you want.

Imagine alarge group of children getting onto a bus. If the bus is empty they can allsit together and where the teacher tells them. If though the bus is crowdedthe 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 oftheir 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 itin time, and then you get an error. A disk failure's a rotten experience. I've had a couple in my time, but Idon'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 itonce, and it may have just been coincidence that the disk failed at the sametime, 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.

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 toEngineers making mistakes that are too awful to explain meant I ddevelopeda 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----- Original Message ----- From: "john coley" <johncoley@xxxxxxxxxxxxxxxx>To: <jaws-uk@xxxxxxxxxxxxx> Sent: Thursday, October 16, 2008 12:44 PM Subject: [jaws-uk] computers running slowly 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.
