Best practices for partitioning a hard disk

I'm often asked, "What's the best way to partition your hard drive?" Typically, I answer, "What do you mean by 'best'? Are you looking for the best performance? Best reliability? Best usability?" There's no single answer to how you should partition hard disks on a computer running Windows XP. What I can offer are some suggestions based on my personal experience.

Depending on your budget and goals, you can choose the solution that works best for your system. In this column, I'll focus on three areas where your partitioning scheme can really make a difference:

• Organizing your work

• Safeguarding your data

• Boosting your computer's performance


I'll describe the partitions I created for my computer and explain the benefits you can gain from dividing your hard disk into more than the single partition and hard drive that it originally came with. These benefits can help you be better organized, more productive, and ensure the integrity of your data.

Overview of my partitioning scheme

Partitioning helps me manage my work, especially on the computer that I use most for my writing. The figure below shows the two physical disks partitioned as follows:

• Disk 0 has a System partition (drive C) and a Data partition (drive D).

• Disk 1 has an Archive partition (drive E), a Research partition (drive F), an Other partition (drive G), and a Paging partition (drive H).

Here's how you might set up a partitioning scheme similar to mine. You can adapt these steps to meet your own needs:

1.
Install Windows on drive C on your first hard disk.

2.
Create a second partition on your first disk to store your active work files, and keep it fairly small so you can maintain it more easily. Unless your work is graphic design or video production, since your work files will be much larger.

3.
Install a second hard disk on your computer and create at least two partitions on it, one for your paging file and the other for archiving old work files and other important files like your Outlook PST file.

4.
Create additional partitions on your second disk only if they will contain files that are infrequently accessed to minimize contention with the paging file partition.


Organize your work
Whether you use your PC for work or play (or both), partitioning your hard drives appropriately can help you keep organized. Disk partitioning is invaluable to me, because I'm a notoriously disorganized person. My desk tells the tale—piles of paper all over the place, sticky notes attached to monitors and walls, stacks of open books, and leftover crumbs from snacking. You can imagine what my hard drives must look like.

What's the value of using my partitioning scheme? Installing the operating system and applications on a dedicated partition (System) provides these benefits:

• Makes my computer easier to maintain without worrying about losing work when things go wrong.

• Need to defragment this partition only after I install a new application, which is rarely because my computer is dedicated to writing and editing work, not fun and games (I have other computers for that).

• Can easily use System Restore if something goes wrong so I don't lose time from my work.


I store all my active work files on drive D and keep the folder structure on this drive simple: one main folder for each project I'm working on. My Data partition is fairly small at 2 GB. (This small size usually works unless you work in video production or graphic design, in which case your work files may be huge.) The small-sized partition and folder structure help me:

• Find my work quickly and keep it organized.

• Promptly move suspended or inactive projects to the Other partition until I need them or until they're ready to be archived to the Archive partition.

• Defragment the Data partition more quickly, which further reduces potential downtime.


This last item may not seem like a big issue since you can schedule defragmentation to occur during off hours. But as a writer, I often find myself getting out of bed in the middle of the night to outline an idea. It's painful to wait for your computer to finish a process before you can use it.

Tip: I also have a Research partition on my second disk. That's where I save copies of white papers and other background material I find while doing research for a writing project. Most writers are packrats and I'm no exception. Keeping such research separate from my own writing helps ensure I don't accidentally merge text someone else wrote with my own work.

I've tried other partitioning schemes to organize my work and found them wanting. For example, on a previous computer I had six partitions instead of four on the second hard disk. I found out the hard way however that these smaller partitions filled up faster, so I either had to save my work on partitions where it didn't belong or spend extra time moving whole volumes of data from one drive to another—not fun. So now I keep things simple with just enough partitions to help me stay organized.


Safeguard your data
The Archive partition on my second physical disk is a large partition that I use for backing up data quickly. This helps protect my work from disappearing should my first physical disk fail.

What I do to protect my work is simple. At the end of each day, whether my current writing project is finished or not, I do the following:

1.
Copy its subfolder (for example, D:\Expert Zone\January 2005) from my Data partition to a new subfolder I created in my Archive partition.

2.
Name the new subfolder in Archive by date and project, for example E:\050109 Expert Zone, which indicates a backup of writing I did for Expert Zone on January 9, 2005. Keeping the date first in subfolder names helps me more easily find something I was working on a few days ago in case I need to restore an earlier version of a document.


3.
If I've been working on multiple projects that day, I copy each project's subfolder from Data to a separate new subfolder on Archive, with each of these new subfolders having the same YYMMDD but a different project name appended.


But instead of manually copying files like this, why don't I just run the Backup or Restore Wizard to save incremental or differential backups on my Archive partition? Basically, because I'm impatient—if I need access to old files from a project I'm working on, I don't want to have to have to restore the data from backup first. I can also usually find what I want faster by browsing for it by YYMMDD-dated folder than by searching through a backup catalog for the right file.

Tip: I do use Archive for one standard backup though. I back up my System partition using Automated System Recovery (ASR) and store this backup on the Archive partition.

My Archive partition tends to fill up pretty fast however because I am always saving temporary versions of my work as I go along. So in addition to having two physical disks on my computer, I also have a CD-R drive that I use to burn CDs for two purposes:

• At the end of each month I copy last month's Archive subfolders to CD, label it by date, and put it somewhere safe. That way I have last month's backup ready if both my hard disks fail from a lightning bolt hitting my office, or my computer is infected with a virus, or a thief steals my computer.

• When my Archive partition is approximately 80 percent full, I copy several months of the oldest backup files to CD and then delete them from the Archive folder to reclaim space.


I also copy my Outlook .pst file to my Archive partition once a month. Like most writers, I depend heavily on e-mail and can't afford to lose old e-mail messages or contacts. Since .pst files can be fairly big, I usually keep only a few months of them archived this way. And I copy my current .pst file to CD every few months and delete older .pst files from drive E to reclaim space for other backups. Once I've safely saved my current .pst file, I go through Outlook mercilessly deleting folders for projects I'm no longer working on.

Boost performance
Although a PC used for writing doesn't need to be a high-performance computer, its performance can be improved by a good partitioning scheme. The biggest boost comes from my Paging partition on drive H, which is found on my second physical disk. I use this partition to boost performance in the following ways:

• Move the paging file there. A well-known method for improving performance on a Windows-based computer is to move the paging file (pagefile.sys) from its usual location on drive C to its own separate partition on a separate physical drive.

• Keep the Paging partition small (4 GB). By default the initial size of your paging file is 1.5 × RAM and its maximum size is 3 × RAM. So if your computer has 1 GB of RAM, which is pretty good for a desktop productivity computer, then setting your Paging partition to 4 GB gives you more than enough room for your paging file without wasting disk space that could be used for other purposes like storing data.

• Format it using the FAT32 file system. Although the version of NTFS in Windows XP has features that make it perform better than earlier versions of NTFS, you can still eek out some performance gains for small volumes by formatting them as FAT32 instead of NTFS. I'm not overly concerned about the lack of security from not having pagefile.sys protected by NTFS permissions since it's an unreadable binary file. If someone hacked into my system, they wouldn't need to bother with the paging file anyway.

• Replace old 5400 rpm drives with newer 7200 or 10000 rpm drives. If you have the budget, you can speed performance of disk activity by installing one of these faster drives.


If you have IDE drives, you can also boost file system performance by setting both physical disks as masters on separate channels. That way data can flow freely and simultaneously between both disks and the system bus. This setup allows Windows to access and load system files while simultaneously paging to disk. The end result—increased performance. Of course, Paging isn't the only partition I have on my second disk. But since I only access the Archive and Other partitions only a few times per day, the disk is pretty much dedicated to paging activity. But overall the biggest performance gain is usually achieved by moving your paging file to a partition on a separate drive as described above, especially on a system that has limited physical memory. Buying more RAM is of course another way to boost performance.

Tip: NTFS tweaks can also help squeeze some additional performance as I describe in NTFS Performance Hacks.


Whether you spend most of your time working or playing on your system, partitioning your disks appropriately can help you keep your work organized, your data safe, and your system humming along. Of course, don't forget to back up all your data before you start partitioning your disks!

Sure-Fire Fixes for a Problem PC

Is your PC troubled? Maybe it has the blues (it wants to be a Mac). More likely, it's suffering from any of a dozen things, such as a corrupt file, a bad app, or even a moribund CMOS battery. Read on for PC therapy.

The Hassle: My PC freezes periodically. How do I unfreeze it without losing my work or having to reboot?

The Fix: In Task Manager, select the Processes tab, choose Explorer.exe, and click End Process. (Just ignore the scary message.) Select File, New Task (Run...), type explorer, and click OK.

The Hassle: Your advice helped me unfreeze my system--but it keeps happening, and I can't go on like this. What now?

The Fixes: Start with the usual suspects: Scrub your Temp and Internet cache folders. First, use CleanCache 3.0 (see Tool of the Month on the next page of this article). Then run Windows' Check Disk utility with Automatically fix file system errors and Scan for and attempt recovery of bad sectors checked. (Open My Computer, right-click the drive, select Properties, choose the Tools tab, and click the Check Now button under 'Error-checking'.) Also, send your antispyware and antivirus tools into action.

No luck? Try getting rid of damaged ActiveX programs. From Control Panel, choose Internet Options, the General tab, Settings, and View Objects. Right-click to delete any items marked 'Damaged' in the Status column. You might have a corrupted file, so run System File Checker to verify (and, if necessary, reinstall) those files on your system: Click Start, Run, and then type CMD. In the command window, type sfc /scannow and wait awhile; the scan seems to take forever to complete.

If your PC is still having problems, they may be more deep-rooted. You'll have to try a few techniques to figure out which program or process is causing the freezing. Sysinternals has three superb free diagnostic tools. FileMon gives you a real-time view of every running program and lets you know what it's doing, recording and time-stamping each action an app takes; watch for a specific program's behavior just before a freeze. RegMon does the same for the Registry, while Process Explorer does the dirty work on Windows processes.

Boost your computer's performance by clearing the tray of useless icons

Want to see the winner of the most bloated system tray award? It weighs in with 30 icons and counting. This month I'll tell you how to shake the system tray free of worthless items while retaining the essential ones.

The Hassle: Every time I boot up my Windows XP Home system (which takes forever), heaps of icons appear in my system tray. I checked my Startup folder and, except for two items, it's empty. Where are these programs coming from, and do I need to keep them all?


The Fix: Your computer's definitely stressed. There are two issues. First, every time you boot, Windows has to load the programs or processes represented by some of those icons. Second, and more significantly, they're gobbling up resources and CPU cycles, slowing down your system. It's a safe bet (I'll even give you odds) that plenty of the items are useless, can be dumped, and won't be missed.

Removing the junk from your system tray can be an exciting adventure. (Stop laughing. It's better than emptying the dishwasher, right?) Determining what applications are loading behind the scenes is the easy part; figuring out which ones you can safely remove is harder.

My cohort, Woody Leonhard, scratched the surface of the system tray in January's "Gunk Busters" feature. I've got more to say, and it's summed up in two words: WinPatrol Pro. The latest version, 9.8, is a must-have tool.

WinPatrol works in two ways. First, when you install a program and it tries to add an icon to the tray at boot-up, you'll get a WinPatrol warning--and a way to nip it in the bud (or kill and remove it afterward). That's important for programs such as AOL, Apple's QuickTime, and RealPlayer, all notorious for adding junk icons. WinPatrol also enables you to stop programs such as Adobe Acrobat that insist on running useless, daily version-update checks; and it prevents programs from changing file extensions willy-nilly.

Second, WinPatrol gives you an easy way to comb through existing background-loading programs; its 'info' button provides basic details, including the company name, version, and startup location--enough to help you figure out which entries are removable. The free version is good, but I strongly urge you to spend $25 for the Pro version. Its comprehensive database gives you more details and specific recommendations for which programs to keep and which to remove. I promise you'll get that money back by eliminating your system tray headaches.

Quick tip: Rather than remove an entry, I use WinPatrol's Disable feature until I am sure the entry is unnecessary.

WinPatrol also removes tracking cookies, monitors services, watches Internet Explorer helpers, and blocks Sony's annoying rootkit-like DRM scheme.

By the way, if you want lots of programs running from the system tray, don't mind the clutter, and are willing to spend some bucks, you can improve your PC's startup speed simply by adding more RAM. I maxed out my computer with 2GB and rarely experience resource issues.

Tool of the Month: Unclutter Your Desktop

I preach neatness, but my notebook's desktop is an unholy mess, with icons everywhere. That's fine with me--until I have to do a presentation and everyone gets a look at my disorderly desktop. My trick is to use an obscure feature built right into Windows to temporarily hide my desktop icons. Right-click your desktop and uncheck Show Desktop Icons under Arrange Icons By. This tactic is also ideal when I need to capture a screen shot of a dialog box and want a blank background.

Website's Back Door

Ever experienced this? You ask Google to look something up; the engine returns with a number of finds, but if you try to open the ones with the most promising content, you are confronted with a registration page instead, and the stuff you were looking for will not be revealed to you unless you agree to a credit card transaction first....
The lesson you should have learned here is: Obviously Google can go where you can't.

Can we solve this problem? Yes, we can. We merely have to convince the site we want to enter, that WE ARE GOOGLE.
In fact, many sites that force users to register or even pay in order to search and use their content, leave a backdoor open for the Googlebot, because a prominent presence in Google searches is known to generate sales leads, site hits and exposure.
Examples of such sites are Windows Magazine, .Net Magazine, Nature, and many, many newspapers around the globe.
How then, can you disguise yourself as a Googlebot? Quite simple: by changing your browser's User Agent. Copy the following code segment and paste it into a fresh notepad file. Save it as Useragent.reg and merge it into your registry.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Micro$oft\Windows\CurrentVersion\Internet Settings\5.0\User Agent]
@="Googlebot/2.1"
"Compatible"="+http://www.googlebot.com/bot.html"

[Replace '$' to 's' from registry address line of above code] Voila! You're done!

You may always change it back again.... I know only one site that uses you User Agent to establish your eligability to use its services, and that's the Windows Update site...
To restore the IE6 User Agent, save the following code to NormalAgent.reg and merge with your registry:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Micro$oft\Windows\CurrentVersion\Internet Settings\5.0\User Agent]
@="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"

[Replace '$' to 's' from registry address line of above code]

Windows XP System Properties logo

The Windows XP System Properties logo is often changed by computer manufacturers. Hardware vendors use this general system information dialog to brand your computer with their own logo and support contact information.

In this tip you can learn how you can insert your own logo in the system properties dialog and complete it with your own contact information.

To invoke the system properties dialog, click the Start button, right-click "My Computer" and select "Properties".

This will open up your general system information dialog. On our Fujitsu-Siemens Amilo Pro laptop, the Windows XP System Properties logo looks like this :



If you want to put your own graphic in there, you should create your image in a .bmp graphic file. It's also a good idea to create this bitmap image with the same background shade of gray (RGB: 192, 192, 192) used in the Properties dialog. Otherwise, you risk letting Windows make its own judgments regarding color contrast and background shading.

The next thing to consider is the image size. The system properties dialog only offers enough real estate for an image of about 180 (wide) x120 (high) pixels. Make sure that you can fit your logo in this area.

Once you have created your logo and saved it as a .bmp file, copy it over to the system32 subfolder of your Windows system folder. If you don't know where your system folder is :

**Click the Start button and select "Run"

**In the "open" field, enter "cmd" (without the quotes) and click ok

**Windows will open up a dos command window

**In the command window, type "set system" (without the quotes)

**Look for the line that contains "SystemRoot", this is where your system directory is (generally, the Windows XP system folder is c:\windows)

Now that you know where your system folder is, copy your logo image file over to the system32 subfolder of your system folder. Then rename your logo image file to oemlogo.bmp

Additionally you can create a new file in this same folder and name the new file oeminfo.ini

In this file you can enter your contact information like in the example below :

[General]
Manufacturer=Windows Help Central
Model=ShowCase

[Support Information]
Line1=" "
Line2=" For support, sales, upgrades or questions:"
Line3=""
Line4=" Some text to demonstrate the XP System Properties logo"
Line5=" Windows XP Tips and Tricks "
Line6=" yadayada"
Line7=""
Line8=" +1 (888) 888-888 (voice)"
Line9=" +1 (888) 888-889 (fax)"
Line10=""
Line11=""
Line12=" http://windows-help-central.com/"

Save and close the file and you are ready. From now on, if someone opens up the system properties dialog, your own Windows XP System Properties logo is in there.



And if someone clicks the "Support Information" button :

Increase broadband connection speed in Windows XP/2003

This tip is designed for increased BROADBAND speed in Windows XP while using standard Network Interface cards (NIC) that are connected to ADSL modems, or when using any directly-connected USB ADSL modem.

To speed up the Internet connection speed we need to configure a special buffer in the computer's memory in order to enable it to better deal with interrupts made from the NIC or the USB modem.

This tip is only recommended if you have 256MB RAM or higher.

Step #1 - Identify the IRQ used by the NIC/USB modem

Follow these steps:

1. Open the System Information tool by running MSINFO32.EXE from the Run command.

2. Expand System Summary > Hardware Resources > IRQs.

3. Look for the listing made for your NIC (in my case - a Intel(R) PRO/100+ Management Adapter). Note the IRQ next to the specified line (in my case - IRQ21).

In case of USB modems you will first need to find the right USB device used by your modem. Follow these steps:

1. Open the Device Manager tool by running DEVMGMT.MSC from the Run command (or by right-clicking My Computer > Hardware tab > Device Manager button).

2. Scroll down to Universal Serial Bus controllers and expand it.

3. Right-click the USB Root Hub and select Properties. Note that you might need to do so for all listed USB Root hubs (if there are more than one) in order to find the right one.

4. In the Power tab, look for your USB ADSL modem.

5. In the Resources tab look for the assigned IRQ (in this case - IRQ21).

6. This is the IRQ we're looking for.

Note: IRQs and modem names might vary...

Step #2 - Modify the system.ini file

Follow these steps:

1. Run SYSEDIT.EXE from the Run command.

2. Expand the system.ini file window.

3. Scroll down almost to the end of the file till you find a line called [386enh].

4. Press Enter to make one blank line, and in that line type

IrqX=4096

where X is the designated IRQ number we found in step #1, in my case it's IRQ21.

Note: This line IS CASE SENSITIVE!!!

5. Click on the File menu, then choose Save.

6. Close SYSEDIT and reboot your computer.

Done. Speed improvement will be noticed after the computer reboots.

The most speed improvement is visible with USB A/DSL modems, however there are reports that this tweak also does good for regular NICs. In any case, it won't harm your system, so why not try it yourself and let me know what you find.

To Increase Your Internet Speed On Windows XP Professional

TCP/IP Settings for Increasing Internet Speed

I've found that Windows XP is largely self-tuning. Currently I'm running XP Pro and I get 600K download speeds box stock. So you might not wish to modify the RWIN size if your speed is acceptable.


However, If you do want to change your RWIN setting, I have found that the best starting modification to make is to add an entry in the registry that creates a receive window size of 64240.


To install this modification, Right-Click on this file

WindowsNT2000XP-64240 RWIN.reg

and select 'Open'.


Select 'Open' again and you will be asked if your are sure you want to install this information in the registry. Select 'Yes' and than re-boot your system at your convenience.


This file adds the TcpWindowSize entry to the registry and sets a value of 64240. It also adds the Tcp1323Opts entry and sets it to 0. Neither of these entries exist in the unmodified operating system.


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpWindowSize\64240

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Tcp1323Opts=0

To return your Windows XP computer back to the original settings

Save This File

to your desktop and than right-click on it and select install. This will remove both of the entries and it will be as if you never changed it - once you've re-booted your machine.
