To stop thrashing hard drive in Windows XP, alter the setting of memory from the default (adjust for best performance of programs) to 'adjust for best performance of system cache'. There are no bad side effects.

All the above suggestions are 'over my head' so, I guess I will have to listen to the growling that is called thrashing by the literate above. I, too, wonder if this is taking up disk space which seems to be decreasing as time goes by and I do not add downloads or new programs. Defrag.,scanned often.

If your machine is tweaked to perfection, and you have not disabled optimise hard drive on idle, and you have smallish clusters and or lots of data on your drives, defrag hangs.

Norton 2006, Outlook cleanup, Outlook Express Cleanup, Scheduled Disk Doctor defragmenting, Viruses and Spyware also do create the same disk slow scenario.

Personally, I disable deframgenting when idle, format my drives with 64K clusters (lose a bit of space but pickup loads of disk speed), and defrag via bat file on startup.

It's a good idea to disable system restore on non essential drives. I actually don't use it, as my OS is installed on a partition, and Documents and Settings and data files are on another, that is backed up. On system failure, I reinstall the OS and programs, do some registry tweaks, and point my data files to certain folders, and I'm back in business.

I've had so many problems with Windows on our network the past month. Viruses have been on the increase. I'm moving some machines over to Linux and running Windows in a virtual machine for certain applications. I will still however need a single Windows dedicated machine for certain software.

I believe it is Norton Antivirus 2006 Autoupdate program that is stuck and is causing problems. Symantec who own the product won't help find the answer without a 39.95 Euro charge and suggested I contact a local engineer to get my problem sorted. Any help appreciated...

Hello Leo,
My laptop has been thrashing the HD, Also MS WORD won't open and after it tries it leaves a rectangle of screen that does not repaint on the desktop also Norton Internet security 2006 does not open. I have phoned Symantec and run SYMNRT.exe and reinstalled Norton Internet security 2006 and reinstalled Norton Ghost 10 and reinstalled Word 2003 pro but I am right back at the starting point. Ctl Alt Del does not shut the computer down so I have to manually shut it down. The last time I restarted the laptop the screen was black so I manually shutdown again, after leaving the laptop shutdown for an hour I restarted it and it opened fine but the above problems are still there any help appreciated.
My laptop specs are
990 Megabytes Installed Memory, Slot 'U5' has 512 MB, Slot 'U6' has 512, Windows XP Professional Service Pack 2 (build 2600), 2.67 gigahertz Intel Pentium 4, 8 kilobyte primary memory, cache, 512 kilobyte secondary memory cache, 40.00 Gigabytes Usable Hard Drive Capacity, 26.93 Gigabytes Hard Drive Free Space, SiS M650 [Display adapter]Default Monitor,

Actually, try letting it "thrash" for a while. Outlook compacts its PST file in the background at idle time. At some point the file will have been compacted, and the thrashing should stop. (And technically it's not thrashing ... unless it somehow impacts your ability to do other things.) Conversely you could force compaction and see if that makes the thrashing stop as well.

Hello Leo & Everyone

My hard disk has started thrashing whenever Outlook 2003 has been running on idle for a few minutes. If I close Outlook 2003 the disk stops thrashing.

I tried FileMon and captured the screen as soon as the thrashing started - it was full of the line "OUTLOOK.EXE:2144"

The machine is running Windows 2000 Pro with Service Pack 4. It has 1.5Gb of RAM and the hard drive is a 123Gb IBM. Can anyone help me?

Many thanks

Simon.

Nicely done Leo. Systm restore was using a LOT of resources. All is quiet now...

Thanks,

My Pc's hard disk is still 85% full after all cleaning and removal of non-necessities. After defrag. there is not very much free space leftover either. I removed a bunch of media files and it seemed like I had less space after I erased them. How can I clean it up without compromising the programs and files that I have(which isn't very many).Thanx for your help.

Only 128mb of ram under WinXP is likely to be one of your problems. Your swap file is consuming it all. Buy at least 512mb of ram, preferably 1gb to run XP. You likely have an onboard video card which is consuming 32mb of your system's ram which is why only 96mb appears under Windows. Does your motherboard have an AGP port? If so, I'd recommend buying a videocard for it. Check whether the motherboard supports AGP 1x / 2x / 4x / or 8x and buy a compatible video card.

Your hard drive will thrash because you've told it to have 784mb minimum swap file. The access time to your hard drive is magnitudes slower than for your ram. Hence your system runs like a dog.

PC very slow, upto 3 mins opening or closing progs prog seems to "wash" down the screen, icons disappear leaving only background pic for 5-10 secs, then reappear); hardisk access light almost continuously on, etc.(1)Resorted to original config. using System Restore, but initial improvement, then back to SLOW;(2)Configured WinXP for best performance, with virtual memory set at 754 MB (min) and 1024 MB (max) as per suggestions of HP customer support;(3) Virus checks (Norton, AVG) are clean;(4) SpybotS&D and Ad-Aware cleaned adware/spyware and now show clean;(5) Used a RegCleaner to clean the system without alteration;(6)installed and enabled firewall (successively by Norton, WinXP and ZoneAlarm Pro);(7) at HP customer support's suggestion, closed all startup progs except antivirus and firewall, used Disk Cleaner & Defrag, then restarted the pc. Even uninstalled some progs I didn't use frequently, all to no avail; (8)HD capacity shows drive C is 29% free (9.7 GB) and drive D 15% free at 6

A *new* common cause is Windows XP's System Restore. It monitors changes to a wide range of files and squirrels away restore information. This often looks like unexpected disk activity as it does so.
