Before You Need Data Recovery - Virus Protection Key to Healthy Computing
Tuesday, October 2, 2007
Computer viruses are proving to be highly complex but preventing viruses from infecting your computer systems is simple. Use two well-known brands of anti-virus software and keep them as current as possible.
Beyond that, there are some simple, common sense procedures that everyone should use, whether at work or in the home computing environment. Never open a file whose origins are unknown. In a simpler day, that wisdom only applied to executable files, or files that did something. They have the suffixes .exe, .com and .bat and each can start a program on your computer. These viruses spread through games downloaded from the Internet, on borrowed diskettes and through the old 'bulletin board' services.
Today, unfortunately, a whole new wave of viruses has been unleashed on unsuspecting computer users because software manufacturers introduced feature-rich new programs without considering how vulnerable they are to viruses. Now, almost any document and many email messages can carry and spread 'macro' viruses at lightning speed. That's why it is so important never to open messages or documents from unknown sources. Viruses can delete data, change file names or even damage the physical media the data where the data is stored.
How important is virus protection? If your data is critical to your business operations, there is nothing more important. Even though about 75 per cent of all data loss incidents are caused by human error or system malfunctions, a virus attack can still cripple your data center. A combination of regular, verified backups and constantly updated virus protection are absolutely essential to protect your data - and your organization.

Data Recovery Tips
Tuesday, August 7, 2007
When it come to computer blow problem, data recovery is a must to secure the important files and folders, movies and the pictures of beloved one and etc. Nowadays there are plenty of free data recovery software the paid one on the internet. We also can find the way how to DIY this data recovery from the internet. There are many guides and easy data recovery step and trick to do it so. The main problem for computer data recovery and laptop data recovery is data recovery from hard drive and external hard drive data recovery. Hard disk data recovery or hard drive failure data recovery can be done using some data recovery tools and technics.
Caution should always be used when dealing with hard drive failure or any other type of computer problem. Reacting with panic will usually make the problem worse.
Here are several tips:
Do's
- Backup your data frequently.
- If you believe there is something wrong with your computer shut it down, do not continue to power up because you may do more damage.
- If you here a clunk, clunk sound when you power up the drive, shut down! Do not panic nor turn the power button on and off.
- Package the drive properly when you send it in to a data recovery specialist. You can cause additional damage to the hard drive if it is poorly packaged.
Don'ts
- Do not ever assume that data recovery is impossible; even in the worst cases, such as natural disasters data recovery specialists have been able to retrieve valuable data.
- Never remove the cover from the hard drive; this will only cause further damage.
- Do not attempt data recovery with commonly available software utility programs.
- Do not rest your computer on a moveable object or piece of furniture. Shock and vibration can result in serious damage to the hard drive.
- Do not subject the drive to extreme temperatures changes both hot and cold.
- In the case where a drive has been exposed to water, fire or even smoke do not try to power up, the situation calls for a professional.
When travel the hard disk, the packaging method also important. The best packaging material to use when sending out a drive is the original box it came in. If the drive came in an anti-static bag only, or was part of a desktop system, then using foam rubber would be your next logical choice. Remember to wrap the drive in an anti-static bag before packaging.
Too many times people use packaging materials that are not successful in keeping the drive safe such as bubble wrap, foam peanuts or paper. Bubble wrap can be used if you absolutely cannot get your hands on foam rubber. Just make sure that the drive is packaged in such a way that it cannot move around inside the box.

Hard Drive History – 50 years in the making
Friday, August 3, 2007
Today marks the 50th anniversary of hard drive storage. When IBM delivered its first hard drive on September 13th, 1956, few could have imagined the impact it would have on our everyday lives. The RAMAC (also known as 'Random Access Method of Accounting and Control') was the size of two refrigerators and weighed a ton. It required a separate air compressor to protect the heads, had pizza-sized platters and was able to store a then whopping 5 megabytes of data. Now you can do all that with a mere pocket drive! What's more - the RAMAC was available to lease for $35,000 USD, the equivalent of $254,275 in today's dollars.
25 years later, the first hard drive for personal computers was invented. Using the MFM encoding method, it held a 40MB capacity and 625 KBps data transfer rate. A later version of the ST506 interface switched to the RLL encoding method, allowing for increased storage capacity and processing speed.
IBM made technological history on August 12, 1981, with the launch of their first personal computer - the IBM 5150. At a cost of $1,565, the 5150 had just 16K of memory- just enough for a small amount of emails. It's difficult to conceive that as recently as the late 1980s 100MB of hard disk space was considered ample. In today's era, this would be totally insufficient, hardly enough to install the operating system, not to mention a large application such as Microsoft Office.
When asked about the limitations of the early PC, Tom Standage, the Economist magazine's business editor says: "It's hard to imagine what people used to do with computers in those days because by modern standards they really couldn't do anything."
As a result of these major breakthroughs, the industry has grown from several thousand disk drives per year in the 1950s to over 260 million drives per year in 2003. During this period, the cost of magnetic disk storage has decreased from $2,057 per megabyte in the 1960s to $.005 today.
The future is bright
At present, the standard 3.5 inch desktop drive can store up to 750 gigabytes (GB) in data. But disk drives are set to become even smaller, more powerful and less costly. According to Bill Healy, an executive at Hitachi, drives containing hundreds of gigabytes will be small enough to wear as jewelry. "You'll have with you every album and tune you've ever bought, every picture you've ever taken, every tax record."
Having five disk drives in your household is becoming increasingly commonplace: PCs, laptops, game systems, TiVo® video recorders, iPod® - just to mention a few. Experts believe that someday households will have up to 15 disk drives, some of which may appear in your TV set, cell phone or car.
In fact, the industry is expected to deliver as many drives in the next five years as it did in the last 50 years. Industry analysts such as Gartner, IDC and TrendFOCUS believe that the global hard drive market will continue to experience impressive unit and revenue growth.
