How to Install a New Hard-disk

Running out of hard disk space, yet also want to keep all the files that are currently on the system in perfect order? Install an extra hard disk, and see your available space rise!

Firstly, make backups of your existing system files. You may never know when these may come in handy. If your current hard disk may go down the pan, you'll be glad to have something to start with again. Also, if you want to use all your data that is on this drive, back it up anyway; ready to be transferred to the new drive. Also, create a system disk for your PC. This can be created by going to Control Panel > Add/Remove Programs, and then the "System Disk" tab. The instructions should be there for you. "WHEN I INSTALLED MY EXTRA HDD I DiDNT FOLLOW ANY OF THE ABOVE MENTIONED....INSTEAD JUST OPENED THE CABINET AND LOOKED FOR THE WIRES AND CONNECTED THEM ...ANY ONE CAN TELL WHERE THE CORRECT WIRE GOES ..... THE MAIN THING IS TO MAKE SURE THAT THE BROAD THIN GRAY WIRE OR DATA CABLE SLOT WITH THE WORD 'P2' IS CONNECTED TO THE EXTRA HDD"

Once you are prepared on the software side, turn off your PC and open the case to your PC (Please take proper precautions at this point. Anti-static wristbands and other such devices should be used. If you don't have these, just make sure you are properly earthed, and know what you are going to do. Oh, and please turn off the PC properly. I don't want you dying on me, literally!). The hard disk is the metal box shaped thing that is either the size of the floppy drive or it could be the size of the CD-Rom drive. It should be easy to spot, because it might even say "Hard Disk" on it. At this point, look and see where you can put the new drive, and how you are going to connect it up. If there is no hard drive in there, then don't worry; I'll explain how to connect it up as well.

Look at the end of the HDD. It should have a load of sockets and pins for you to play around with. At one point, you should be able to see some pins with some jumpers attached, and a sticker on another side telling you what configuration of jumper positions means what to the computer. If you are attaching it to the same IDE cable as your existing drive, then set it to "Slave", otherwise, select "Master" and fit it as close to the start of the cable as possible (The start of the cable being where it's connected to the motherboard). This cable is an "IDE" cable, and can only be fitted two ways to the drive itself. Look for an indication as to which side pin number 1 is (Look for stickers again!) and insert the IDE cable in that socket and pins, with the red side as close to pin 1 as possible. Then, just fit it into the computer, as you would do any other drive (For the thickies, which means attaching it to the case using the mounting screws that should come with the PC. Before you do this though, note down the extra information on the top of the drive, usually the number of cylinders, heads, sectors, and any other information. Next, connect one of the power cables to the HDD (These are the 4 cable collections with connectors attached, which leads from the power supply unit), and close the PC case.

Next, you will have to mess with CMOS. Turn on the PC, and hit whatever key you are told to at the bootup to get to the CMOS menus. When in there, choose the relevant section (We can't say exactly, because there are many different CMOS set-ups around) and select "IDE Auto-detection". If the hard disk does not appear on it, then you will have to enter the information manually. Use the notes you collected from the top of the hard disk earlier to tell the computer what the hard disk is.

IMPORTANT:
Afterwards, insert the system disk("THE BACKUP DISK THAT CAN BE CREATED BY RIGHT CLICKING A DRIVE4R AND SELECTING FORMAT AND THEN THE CREATE BACKUP DISK OPT") prepared earlier and "Save" your editing of the CMOS and exit. The system disk should work instead of the original hard disk (Or if you are installing from scratch, then it will boot from the A: anyway).
Type "fdisk" at the dos prompt. This runs a program called, surprisingly, FDISK. Tell the computer which drive ie the harddisk is the new one (Please choose the correct one at this point. Make a mistake, and you really could be using those backups!), and then tell it what partitions you want (Don't worry about it, as there are full instructions while you are running the program). Once this is done, you can reset your PC (Except if this drive is being installed from scratch and is on it's own. If this is the case, then you can format the drive by typing "format c:" This will format the drive for you, but what's really good is if you type "format c: /s" instead, as this installs some important files at the same time. Then, just follow the instructions to install whatever OS you are going to use.)
If you are adding this drive as a second HDD, Go into Windows (Or any other OS, but the instructions may be different!) and then format from "My Computer" like you would a floppy disk. There you go: A newly installed hard disk, with minimum effort!....and dont take the risk of formatting any of the drives u know!!!! if in doubt contact me here or don't do at all........."SOD will not be held responsible for any data lost in this process"

How to use the Google calculator

Google’s calculator tries to understand the problem you are attempting to solve without requiring you to use special syntax. However, it may be helpful to know the most direct way to pose a question to get the best results. Listed below are a few suggestions for the most common type of expressions (and a few more esoteric ones).

Most operators come between the two numbers they combine, such as the plus sign in the expression 1+1.

Operator Function Example
+ addition 3+44
- subtraction 13-5
* multiplication 7*8
/ division 12/3
^ exponentiation (raise to a power of) 8^2
% modulo (finds the remainder after division) 8%7
choose X choose Y determines the number of ways of choosing a set of Y elements from a set of X elements 18 choose 4
th root of calculates the nth root of a number 5th root of 32
% of X % of Y computes X percent of Y 20% of 150


Some operators work on only one number and should come before that number. In these cases, it often helps to put the number in parentheses.

Operator Function Example
sqrt square root sqrt(9)
sin, cos, etc. trigonometric functions (numbers are assumed to be radians) sin(pi/3)
tan(45 degrees)
ln logarithm base e ln(17)
log logarithm base 10 log(1,000)


A few operators come after the number.

Operator Function Example
! factorial 5!


Other good things to know

You can force the calculator to try and evaluate an expression by putting an equals sign (=) after it. This only works if the expression is mathematically resolvable. For example, 1-800-555-1234= will return a result, but 1/0= will not.

Parentheses can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3 causes the addition to happen before the multiplication.

The in operator is used to specify what units you want used to express the answer. Put the word in followed by the name of a unit at the end of your expression. This works well for unit conversions such as: 5 kilometers in miles.

You can use hexadecimal, octal and binary numbers. Prefix hexadecimal numbers with 0x, octal numbers with 0o and binary numbers with 0b. For example: 0x7f + 0b10010101.

The calculator understands many different units, as well as many physical and mathematical constants. These can be used in your expression. Many of these constants and units have both long and short names. You can use either name in most cases. For example, km and kilometer both work, as do c and the speed of light.

Feel free to experiment with the calculator as not all of its capabilities are listed here. To get you started, we’ve included a few expressions linked to their results.

1 a.u./c
56*78
1.21 GW / 88 mph
e^(i pi)+1
100 miles in kilometers
sine(30 degrees)
G*(6e24 kg)/(4000 miles)^2
0x7d3 in roman numerals
0b1100101*0b1001

23 Ways To Speed WinXP, Not only Defragment

Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.

1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.


Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.
