How to Clean Disk Data

Posted on 18. Dec, 2008 by Jason Biddle, MSCE Certified Tech.

When selling or throwing away your old PC, be cautious of just what you’re disposing of. There are increasing incidences of identify theft occurring from the data retrieved from the victims hard disk. Sometimes not much effort is even required to obtain this personal information. It’s not too difficult for the buyer of a second hand computer to get hold of data from the machine. Whilst most of the information contained might not be of much use, there have been occasions when the data retrieved has included credit card numbers, medical records, bank account details and other private and personal details.

Before getting rid of your old computer it’s important to wipe clean the contents of your hard drive. There are various ways of doing this; five of them are listed below.

1. Delete Files and Folders

Deleting all files and folders and emptying the recycle bin is one of the most common ways of wiping all data from the hard drive. It’s certainly the easiest; however, this method of data deletion is not completely effective. The file pointer will be deleted preventing the Operating System from detecting it; however it will still exist on the hard disk. Using data recovery software these files will easily be recovered.

2. Reformat the Hard Drive

A reformat of the hard disk will delete all the files held on it. However, this procedure only destroys the structure of the data and it will still be possible to recover any information stored on it.

3. Degaussing

Degaussing involves using a powerful electronic magnet to erase any contents held on magnetic media by reversing the magnetic field.

4. Overwriting the Data

Overwriting the data on your hard drive is another method of removing information. This isn’t considered an effective way of data wiping as it may still be possible to gather information. Also, some files may remain on the disk which have not been overwritten.

5. Destroy the Hard Drive

Destroying the hard drive is one sure fire way of eliminating all the data held on it. However it is a rather drastic measure to take.

How to Wipe the Data

The five methods listed above for data wiping are not sufficient enough to completely remove files from your hard drive or any storage media. However, there is a solution to this which involves using dedicated data wiping software which guarantees the complete deletion of all data held in various types of storage media. Using this software is easy, although the actual processes the program performs are quite complicated.

The program carries out several erasing processes on the hard disk. The first task it performs is replacing all the information on the disk with random patterns of zeros and ones. Next, this pattern will be re-arranged and finally all the ones and zeros will be distributed randomly all throughout the disk. These processes will completely erase all files from the system including admin data, registry information and Windows logs. The original information on the disk will now be unrecoverable. Some software of this type also offer low level formatting and this will wipe the disk totally clean. Using a file shredder program will also have similar results. It uses the same removal methods offered by specialized data wiping programs.

If you don’t want to spend lots of money on data wiping software, then have a look around the Internet as there are many programs of this type available for free. Most of them will be just as efficient as their costly rivals. One of the most popular programs for data wiping is Erasure and it can be downloaded free from the Internet.

Data wiping can be a dull and monotonous process but it is well worthwhile to ensure the complete removal of your personal information from your hard drive. Failure to do so can leave you wide open to becoming a victim of identity theft.

Scandisk – How To Do Your Own PC Maintenance

Posted on 18. Dec, 2008 by Jason Biddle, MSCE Certified Tech.

Computers have come a long way in recent years and are much more stable and reliable than they used to be. This however, doesn’t mean that they no longer need to be well cared for and a regular maintenance schedule is still necessary to keep your system performing well. Maintenance should be carried out frequently, at least once a week. Below are four recommended tasks you should perform to keep your PC in tip top condition.

1. Defragment Your Hard Drive

The hard drive is the principle storage device on any computer. As data gets removed and replaced, the files end up scattered all over the hard disk. This results in a poorer performance by your computer as it must locate all the information from the various segments of the hard drive. Defragmenting your hard drive will speed up the retrieving of this data, thereby making your system perform faster. This involves rearranging the files on the hard drive so that they can be retrieved easily.

Your Windows Operating System comes with a built in defragment application. Before using this, it is a good idea to run a scandisk check first which will test the drive for any errors. To perform a scandisk follow the steps below.

For Windows 95, 98, ME Users: Go to Start – Programs – Accessories – System Tools – Scandisk.

For Windows NT, 2000, XP Users: Right click on My Computer – Select Properties – Tools – Error Checking – Check Now. Select both options and press start to begin the scan.

For Windows Vista Users:

Hit the "Start" button, and in the "Start Search" box, type "scan disk". This should give you the menu option for the ScanDisk.

Once you have run a scandisk check, you may now run a disk defragment. To start this, go to Start – Programs – Accessories – System Tools – Defragmenter. Choose which drive you wish to defrag and the scan will run automatically.

Always close down any other running applications before doing a disk defrag as this will interfere with its operation.

2. Back Up Your Data

It’s likely that most computer users will experience a system crash at some time or another. Unless you have a back up made of any important files, valuable data could be lost forever. Always back up your files.

3. Keep Security Software Updated

Any antivirus or spyware applications installed on your PC need to be kept up to date with the latest definitions. New threats are released to the Internet daily so it is vital to download the latest updates to prevent breaches of security. Set up your security software to update automatically and you will always keep abreast of the most recent threats.

4. Delete Any Unnecessary Files

Clear out your temporary folders regularly to free up space on your hard drive and keep your computer clean and tidy. On your Internet Explorer browser open the Tools tab – Internet Options – General. Choose which files you want to delete.

Perform these four general maintenance tasks regularly to keep your hard drive free from unnecessary information and free up space. This will result in your PC performing in a fast and efficient manner.

5 Ways to Silence Your PC

Posted on 10. Dec, 2008 by Jason Biddle, MSCE Certified Tech.

Computers play an ever more essential role in our daily lives, helping us carry out a variety of tasks that make life easier and more convenient for us. Home computers have developed over the years into fast and powerful machines capable of running at incredibly high speeds. However, along with the impressive performance levels some users may find their PC emitting an equally amazing noise. If you’d like your computer experience to be a noise free event then it’s important you know how to silence that PC.

Cut the Cost of a Noise Free PC

Almost all the cures for a noisy computer are relatively inexpensive or even better – free. Below is a guide to enjoying a silent computer.

1. Place your PC on a flat surface. To avoid any unnecessary vibrations, it’s important to ensure your computer case is situated on a flat surface. You can use mats or other similar materials if needed to keep it firmly in place.

2. Secure internal components. To prevent rattling noises emitting form your PC, make sure all internal parts are held securely in place. Check the hard drive, fan and any other movable parts. Use a screwdriver to tighten firmly if necessary.

3. Check for dust. Using a screwdriver, carefully remove the outer casing of the CPU unit. Inside you will see the motherboard and other items of hardware necessary to run your PC. It’s quite usual for large amounts of dust to accumulate around these areas.

4. Check your screen. Examine your monitor for any signs of noise. Even a barely audible sound now can get serious if not attended to.

5. Eliminate any grime. One common cause of noise is the accumulation of dirt and dust around the fan. Using a can of compressed air, blast away any grime gathered around the internal components.

If the above helpful tips fail to resolve your noise issues, you may choose to replace some of your PC hardware. Usually you will find it is the fan causing the problem so it may be worthwhile investing in a new one

Normally the fan will be situated inside the CPU unit and occasionally a PC may have more than one. There are many types and designs available to purchase although the more silent the fan, the more expensive it usually is in price. However if its silence you’re after, it’s definitely worth the investment.

5 Tips on How to Clean My PC

Posted on 10. Dec, 2008 by Jason Biddle, MSCE Certified Tech.

It’s important to maintain the software on your PC by performing regular checks and scans to resolve any problems which may occur and also to stop any glitches from happening in the first place. Disk cleanup, defrag the hard drive, spyware and adware removal, virus scans and Windows registry checks are all imperative to having a computer running at its optimal performance levels.

What happens if you perform these activities on a regular basis and still find your PC running slowly or crashing? The most probable reason for this and one overlooked by many people is a dirty computer. The build up of dust that gathers around the CPU unit, the processor, the power supply and the ventilation area can seriously inhibit the performance of your PC.

Not only is dust and dirt a menace but cigarette smoke, pet hair and various other substances can all contribute to the performance issues you may be experiencing with your computer. It’s just as essential to have a regular hardware cleaning schedule as it is to have a software clean up.

Before you start cleaning your PC it is important to use the correct tools and know how to carry out the work safely, avoiding damage to the components of your computer. Below is a list of what you will need:

1. Screwdrivers of various sizes

2. Cotton cloth

3. Glass Cleaner

4. Anti static wristbands

5. Rubbing Alcohol

6. Tweezers

7. Compressed Air

8. Lint free cloth or rag

The following steps should be used as a guide to cleaning your PC:

1. Read the owners manual. This will provide the correct instructions on how to clean your computer. Check to see if it gives any helpful tips.

2. Switch off the computer and disconnect power supplies for safety reasons.

3. Remove the CPU casing. You will need to use the screwdrivers to do this. Carefully remove the screws which hold the cover to the casing. Inside are the motherboard and other important hardware. There will most likely be a large amount of dust and dirt gathered here.

4. Clean the CPU. Use the can of compressed air to blast away any dust which has accumulated on and around the motherboard. It may be necessary to remove any cards installed to give the area a thorough clean. Don’t forget about the slots in the motherboard.

5. Clean any grime from the fan. Blast the compressed air into the PCs fan dislodging any debris found there. Check around the heat sink too for any additional grime.

Don’t forget to clean other exterior parts of your computer as well. This will keep it fresh and looking like new. Wipe your monitor regularly as the static generated by the power supply will attract a lot of dust. Use glass cleaner and a lint free cloth or rag to wipe the monitor in a circular motion.

It’s important to place your PC in an area which is well ventilated. Keep it away from direct sunlight and never expose it to dangerous pollutants such as smoke. Carry out a regular cleaning schedule – every three to four months should be sufficient to ensure a spotless and well maintained computer.

4 Ways To Prevent Expensive PC Repairs

Posted on 09. Dec, 2008 by Jason Biddle, MSCE Certified Tech.

Early detection of any problems your PC may be having is vital to prevent further damage from occurring. Therefore it’s important for every computer user to spend some time looking for any signs of trouble. It’s highly recommended that you keep your PC in good health and you will be rewarded with a fast, smoothly running machine.

Carrying out regular maintenance will alert you to any sign of trouble ahead. Catching any problems early can mean the difference between a simple clean up or a costly repair job.

1. Run Disk Defragmenter

Over time, the data stored on your PCs hard drive will scatter as information is stored randomly according to what free space is available. This will result in your computer taking longer periods to access the necessary files and therefore a slower performing PC. Defragging will shift these blocks of data so they sit simultaneously as much as possible, making your computer locate data much quicker.

How to defrag your PC:

1. Click on Start
2. Choose Programs
3. Select Accessories
4. Click on System Tools
5. Select Disk Defragmenter
6. Choose the drive you want defragmented

Defragmenting the hard drive can take quite a considerable amount of time. Always close down any programs that are running as these may cause the tool to restart every so often.

2. Use Disk Cleanup

The Windows Operating System has an in-built system tool which will remove unneeded files safely from the hard disk. A hard disk which is cluttered with data can cause a slow performing PC. The Disk Cleanup tool is used for the following maintenance tasks:

1. To empty the recycle bin
2. To delete temporary Windows and Internet files
3. To delete unused programs and applications
4. To delete downloaded program files
5. To remove obsolete Windows components

3. Remove Spyware and Adware

Whilst surfing the Internet or downloading files and programs, these malicious pieces of software can be installed on your PC unintentionally. They can cause severe performance problems and can pose a security threat so need to be dealt with properly. Running regular Spyware and Adware scans will remove these unwanted programs and restore your PC to optimal performance levels.

4. Scan Your Registry

With regular installation and removal of programs and even general day to day tasks, lots of information gets placed in the Windows Registry, some of which will no longer be needed. This redundant data overloads the registry, making the PC take longer in locating required information, which in turn slows up your computers speed and can cause your system to stall or crash. By running a registry scan regularly this unnecessary data can be located and removed resulting in a much more efficient registry system and therefore a fast smooth running PC. We highly recommend the newest version of RegCure 2008.

Performing regular maintenance tasks on your PC will root out any problems before damage can be caused.
