How to Avoid Hard Drive Overheating

Even though the hard drive stores data, it isn’t perfect by any means. Hard drive failure is very common with all computers, with no real way to prevent it. Although there are several different reasons why a hard drive can fail, the most common is overheating. Viruses and crashes are common as well, along with theft and accidental deletion.

With the older style and mechanics of hard drives, the RPM speed was low, meaning that the drives wouldn’t overheat. The hard drives we use now days, have speeds between 7,200 and 10,000 RPM, meaning that they can get quite hot when they start working. Computers of this day and age come with fans to cool everything down, with most hard drives including temperature sensors as well, so you can keep track of just how hot your hard drive becomes.


With hard drives today, overheating is a very common problem. The faster hard drives come with speeds of 10,000 RPM, which can make the temperature soar above 70 degrees F, really heating things up inside the drive. The mechanics on the inside are built to withstand the heat, although if things become too hot, you’ll encounter problems. If a drive becomes too hot and ends up losing the data, it may be next to impossible to retrieve the information - no matter how good your data recovery specialists may be.

One area that suffers from the drive overheating is the platters, which are magnetic media. Platters are what carry the data throughout the hard drive. Platters are constructed from optical glass, aluminum, or ceramic and normally coated with a layer of magnetic material. Once the hard drive begins to heat up, the platters will start to expand, which changes their size. When this happens, the magnetic surface on the platters will get destroyed, which results in a loss of data. If the physical area of the platters are damaged, it will result in unreadable sectors.

Other areas of the hard drive that can be damaged due to overheating are the read and write heads, head actuator, and the controller chip. Hard drives are very sophisticated pieces of hardware, and can’t handle overheating. The read and write heads are a common example, as they can easily render the drive useless if they become damaged.

To prevent your hard drive from overheating, you should always make sure that it is cooled properly and well ventilated. You can always get additional fans and coolers, which will improve both ventilation and the flow of air in your computer. You can buy fans and coolers at very affordable prices, which makes them an ideal investment for keeping your hard drive or hard drives cool.

You can also get software that monitors the temperature of your hard drive as well. Whether it’s software, or additional fans, you should always ensure that your hard drives are kept cool. By keeping them cool, you’ll greatly reduce the amount of crashes. You’ll also increase the stability of your hard drive as well, which will make your entire computer perform much better.

Video conferencing allows people at two or more locations to interact through two-way transmission at the same time. Video conferencing is also known as video teleconferencing or visual collaboration. Users require a computer, web cam, microphone, and a broadband connection to participate in videoconference. They can generate natural conversations by seeing and hearing each other. Videoconference of two persons is known as point-to-point while the conference of more than two people is called multipoint conference.

Videoconferencing is very useful way of communication because it saves money as well as time. People can do several business activities or meetings with two or more persons while sitting at office table. They don’t need to go anywhere to meet someone. Basic requirements for video conferencing are guaranteed latency, synchronization and broadcast. It enables people to have face-to-face meetings from a wide distance. Prices of teleconferencing are generally less than costs of travel. It’s an easy way to hold meetings, conduct interviews, give lectures and address employees.

Video conferencing is the best way of communication in medical, legal and educational fields. Normally there are three ways such as computer-based system, desktop system and studio-based system to set up a videoconference. There is a limited field of vision in Computer-based system that is why it is the cheapest way of video conferencing. Desktop system improves the quality of audio and video transmission due to dedicated hardware installed on the computer. Most expensive method of video conferencing is studio-based system that offers best quality conferencing. It is mostly used in large-scale companies and universities. Studio-based system is just like a room that is fully equipped with control systems, document viewers, overhead cameras, vision switchers and slide viewers.

An organization, company, educational facility or individual requires some basic components to take complete advantages of video conferencing. Necessary equipment for videoconferencing is camera that lets user to capture video information at his or her site and transmit to someone on the other site. Video display is used to display video at their site and a microphone to hear the audio material.

Videoconferencing terminals require a compressor/decompressor interface that helps in compressing the information while passing from audio to video to make transmission of materials sufficient over net. It is useful in sending the large files from one computer to another. Codec machine also works for decoding and encoding the useful information. A computer and high-speed Internet connection are essential for a successful video conferencing. High-speed Internet connection makes your video conferencing effective and interesting.

Video conferencing is reliable and an excellent method of communication. Videoconference can easily connect you with other companies. You can generate your business from one place and give instructions to your subordinates. It makes bright future for your business and institution. This pioneering technology keeps your company up to date.

Video conferencing is currently an affordable way of communication. A large range of videoconference units is available in the market. Buyers should check company expansion and system compatibility while choosing the best video conferencing unit.

Most people are aware that there are continuous security issues with Microsoft’s Windows operating system and other programs. However, what most people do not realize is how easy it is to significantly improve your computer’s security and reduce the likelihood of becoming a victim to ever increasingly sophisticated threats that lurk on the internet. These steps should take less than a couple of hours to complete and should not clean out your wallet.


1) Windows Update – the first crucial step you need to take to make sure that all your Microsoft applications have all the latest product updates installed. These updates or “patches” address security vulnerabilities and other issues. Microsoft usually issues these updates on a monthly cycle. Visit the Microsoft website or switch on automatic updates from the Windows Control panel. Even if your “new” computer is second hand this is still a critical first step. If you buy a used computer with Windows XP make sure Service Pack 3 or SP3 is installed.

2) Strong Passwords - people often overlook this but having well thought through passwords is an important element of your computer security. A strong password should include at least 8 characters with a mixture of text, symbols and numbers. As a minimum you need to make sure the services most at risk have a strong log-in password. These services include your bank, credit card, other financial services like PayPal, your email address and any other services like Ebay which hackers can use to generate profit.

3) Anti Virus Protection – while it is fair to say the threat of the computer virus has receded during the last couple of years they can still inflict serious damage on your computer. Part of the reason why the threat has reduced is because PC manufactures are now more frequently bundling anti virus packages with their new computers. For example last year my new Dell shipped with a 90-day trial of McAfee's Internet Security Suite. The best bet here is to purchase a security package which includes firewall and anti virus software as a minimum. Top brands include McAfee and Symantec Norton products. However, Microsoft has recently entered the market with their "OneCare" offering which is very aggressively priced.

4) Firewall - if you are using a broadband connection then a firewall is definite requirement to manage the traffic flowing between your computer and the internet. A firewall monitors the inbound internet traffic passing through the ports of your computer. Better products also monitor outbound traffic from your computer to the internet. As per above the best bet here is buy a firewall application as part of a security package which most vendors offer as standard. If a hardware firewall is included as part of your router package then you do not need anything else. A company called Zone Labs offer a great free firewall product called Zone Alarm which should be used as a minimum. Windows XP does now ship with a free firewall but the product does not monitor outbound communication and therefore I believe does not offer adequate protection.

5) Anti Spyware Tool - this software is the last piece in your basic internet security set up. This tool helps combat spyware and adware. There is a good mixture of free and paid versions on offer. Good free software include Microsoft's Windows Defender, Spybot S&D or Ewido Anti-Malware. Ewido Anti-Malware is frequently recommended in computer help forums. Be careful if you decide to purchase a solution. There are a number of rogue vendors out there which aggressively push products which offer you little value. Stick to trusted names like Webroot's Spy Sweeper or PC Tool's Spyware Doctor. These products always come out well on independent tests.

Cheap and inexpensive laptops are available plenty in number in the market. While buying laptops, price factor alone should not limit the purchase. Cheap laptops are made available to the consumer to suit the budget as well as specific requirements. The person buying a laptop should be very clear regarding the required features, options and then conduct a search to match his needs. The place of purchasing cheap laptops is also important. There are various sources from which a person can buy cheap laptops. Out of all the sources, Internet is considered to be the best place to purchase laptops. A same laptop model can be sold at different prices in different websites. The purchaser can easily select the one with a lesser price easily. Also it is better to avoid impulse purchase as far as laptops are concerned, since it is impossible for a lay man to comprehend the hi-tech lingo associated with laptop computers like the flat panel TFT, WiFi connectivity, wireless and many more features.

Features to be considered before buying cheap laptops:

Processor of the laptop: A processor is very important to run applications and to perform on-screen tasks. The processor should not be less than 3.0 GHz as it may affect the quick performance of the laptop. For day today operation using word processing, e-mail, spread sheets etc the above processor speed is enough. When Pentium processors are bought they assure a longer battery life and at the same time they are quick.

Screen size of the cheap laptops should not be less than 12.1 inches. The screen size of laptops is measured diagonally. The larger the screen size, the higher the resolution, making it easy for viewing more information all at once.

Laptops should have a good battery life as they are carried with the operator for presentations, or for calculations whenever and wherever they are required. A laptop with a good battery life should be able to perform jobs ranging from 3 to 7 hours of non stop work without any electrical charge required in between. Lithium ion rechargeable batteries are an ideal choice.

The hard drive capacity is very important to store large amount of data on to the laptops. A cheap laptop can be chosen with a hard drive capacity ranging from 120 GB to 320 GB depending on the person’s usage.

The keyboards of laptops are different from those of the desktop computers. The keys on the keypad are relatively smaller and are packed closely with each other. Hence, it is very important to see if it can be handled comfortably before purchasing a cheap laptop.

Touchpad or pointing stick inbuilt with a laptop can be more very useful than a mouse connected via USB port. Two USB ports are more than enough for a cheap laptop; in case more ports are required the user can use an external USB hub.

The ideal weight of the laptops should be between 4 – 10 pounds, never go for a more weighing laptop even if it comes for a very cheap amount. In order to reduce the weight of the laptops, external CD drives can be used. For communications a built in Ethernet port is more ideal than the serial ports or infrared ports.

5 Tips To Buying Ink Cartridges For Printers


As a general rule, black ink cartridges are more affordable than color toner. When considering which to purchase, take a moment to think about how you will be using your printer. Will your printouts require color or will they work just as well in black & white? If the answer is ‘yes,’ you will save a considerable amount of money in purchasing the black ink cartridges.

If you are cost conscious and also have a great concern for the environment, purchasing recycled ink cartridges may be your best bet. Not only are these more affordable, but they are also better for the environment as are other recycled products. One of the best places for purchasing quality recycled ink cartridges is Viking Office Products and Staples.


When you purchase any type of ink cartridge, make sure that it is compatible with your printer. Many people are surprised to learn that ink cartridges are designed to be used with a specific model and manufacturer of printers, which should be clearly explained on the outside packaging. If you have trouble remembering the model number on your printer, simply write it down on a piece of paper and take it to the store with you. This will be the single most important information to have on hand when selecting ink cartridges for printers because without the right printer model number, you are not likely to get the right product.

Because ink cartridges are sometimes very expensive, it is often possible to find a real bargain on a printer/ink cartridge combo. A recent visit to a local retail store revealed a single ink cartridge for 29.97. Just beside the ink cartridge selection were several boxed printers. Among them, a new printer and color ink cartridge combo, which was priced at just 34.95. When you consider the difference of only 5.00 and the fact that you could purchase a brand new printer and ink for almost the same price as a single ink cartridge, the better deal was obvious. In this scenario, you could simply resale your former printer on eBay and replace it with the new printer. This just goes to show that a little smart shopping can go a long way in terms of getting the best value for your dollar.

The majority of ink cartridges for printers carry a manufacturer’s warranty guaranteeing your satisfaction. The only way to receive coverage as promised is to retain the original purchase receipt, ink cartridge packaging and warranty information. If your new ink cartridge should fail to work as promised, most manufacturer’s will either replace the cartridge at no cost to you or refund the original purchase price in it’s entirety.
