Hard Disk Data Recovery Still An Important Asset

Hard disks have evolved along the years to be a lot more reliable than their ancestors, but no matter how good they got to be, they are still open to damage and errors that could cause loss of data. If this happens, hard disk data recovery is the solution and a big problem solver if the information on the hard drive is important and not backed up.

A hard disk can crash because of a range of different reasons but the most encountered is an unstable power supply. A hard disk is quite open to attacks from sudden power surges or power outages. Such power problems can cause both physical damage and logical errors. Logical damages are possibly easy to fix with a HDD scan and fixing the disk file system.

In most cases, you can observe some signs or symptoms that the unit is about to crash. An imminent crash will cause frequent disk error messages. If the disk will not be shown during the startup of the operating system or the information provided is incorrect when the disk is analyzed are almost sure signs of hard disk damage. If you can hear your HDD make weird sounds, clicking or whirring, the problem is mechanical and you will need professional hard disk data recovery assistance.

Some regular clues that may suggest hard disk damage are:

* When files are accessed or the system is powered up you might head ticking, grinding or clunking noises
* Problems with the operating system booting process
* Problems reading files that exist on the hard drive

To have your data safe, in case you notice such signs, make sure you back up the drive or the most important information at least. This way you will have an easy solution if the worst happens.

There are software applications that you can use to recover hard disk data and correct logical errors but they are quite dangerous in the hands of unexperienced users. If the information present on the damaged hard drive is of an elevated importance you might want to use the services of hard disk data recovery company.

Laptop Data Recovery Explained

Some things in life are just unwanted, but still, can happen to anyone of us. A thing like this is loosing your data from your laptop hard drive, we don't want it, but can happen. All our important information got wiped out in a second, all of it. You can go to your tech friend or even to a computer store to ask what you can do about it but you will probably receive an answer that you can't do anything with it.

We can prevent this by backing up all our information from the laptop hard drive in time but sometimes we just don't think about it and the worst will happen. We know it's our fault for not backing up the files. The good news is that now, we can investigate and research some data recovery companies and ask them for help.

The process for data recovery from laptop hard drives is usually more succesful then normal desktop hard drives, that's good news also. This is because laptop hard drives were always built for mobility and are designed in such way to prevent severe hard drive crashes. The heads on a laptop hard drive are not likely to touch the platters, this can happen mostly on normal desktop hard drives. Because of this, the process of data recovery from laptop hard drives has a higher success rate compared with desktop hard drives.

Even if it has a higher success rate, the process is still difficult and expensive if done by an individual. If you would think about opening it up you will have to make sure to open it in a class 100 clean room. Bad news is that such a room costs about $50000 - $70000. Your best pick is to find a company that can handle the process for you for a cost.

If you don't want to remove the hard drive from the laptop yourself, most companies will do this for you with no extra cost, you will be able to send them the full system. Also, most companies will not charge you if they will not be able to recover your data after the data recovery process.

Any type of data lost is something nobody needs or want, if data lost happen for your laptop hard drive is good to know that the odds are in your favor. Take some time to research for a good company and with some money you will be able to get your data back soon. After this, make sure to always back up all your data.

Raid Data Recovery Explained

Raid data recovery is somehow different from all other types of data recovery. Most experts advise not to try to recover the data yourself before sending in the hard drives to a data recovery company. This is because most companies found that most of the times simple users try to recover the files all by themselves, they fail and not only. Their actions will make the recovery process even harder and if the lost information is important, someone will be in big trouble. If it's about raid data recovery better handle it quick to the professionals without touching anything.

You don't have to take chances with the recovery, it's advised to research for a data recovery company that can handle the recovery process for you. Sometimes, it can be expensive for a raid data recovery but usually the price you will have to pay for the recovery is way lower then the price you will have to pay in time and resources to have all your data recreated.

There are procedures that data recovery companies always follow when they have a recovery on the line. These procedures are followed exactly and even expand when it comes to raid data recovery. As a first step in any raid data recovery, experts have to make sure that all drives are working. For Raid 0 as an example, it is a must for all the drives to be 100% functional. When they are not functional, the drives will be taken in the clean room and will be repaired.

When all the drives will function normally, clones of all the drives will be made. During this process, your drive will be placed in a write protect mode to make sure the data will not be altered in any way. The normal recovery process will be performed on the cloned drives, again, for increased safety.

When researching for a data recovery company you will notice some of them will offer a service full guarantee, if they don't get your data back, you don't pay. A phone consultation is something that could help you also. They will also offer you absolute 100% confidentiality on your data.

Even if raid data recovery sometimes can become expensive, most companies will not charge you for an evaluation of a complex raid system. If you need the help of the experts, get it, it's the best way. After getting all your data back, make sure to always backup your information from now on.

Choosing a new graphic card is not rocket science

As computers become faster and faster, many of us fail to see that technology has been moving steadily away from the CPU and more into the video card industry. Someone looking for a gaming monster should reevaluate the budget and spend less on the CPU and look more at the RAM (Random Access Memory) and the GPU (Graphics Processing Unit). In a gaming machine, most of the processing is done by the graphic card... and not so much the CPU as one would think. But think about it.... those photo realistic graphics portrayed by most of the new games require a LOT of processing power - 90% of which is handled by the graphics card.

Choosing a new graphic card is not rocket science, but you still have to know what to look for. More video memory does not necessarily mean higher performance. One can purchase an ATI 1300 with 512 Megs of ram on it or a previous generation ATI X800 with 256megs. Most people would think that the newer generation graphic card with the more memory would be faster right? Let's put it this way. Would a 2007 Ford Focus be faster than a 1999 Porche 911 even though it is newer and bigger? No, because the Porsche has a much more powerful engine. Just like the X800 has a much more powerful "Engine" than the X1300.

It is always wise to check minimum requirements on games, before proceeding to buy, to ensure that your graphic card will perform to the required specifications for an enjoyable gaming experience. Always look at the Recommended specifications as opposed the the Minimum Specifications. Minimum specifications are just that. Minimum required making the game work. It won't necessarily be pretty to look at, but it will work. Whereas with the recommended specifications, now it may start to look pretty and smooth.

Points to consider for gaming
Push more towards higher end video cards to enhance your experience
Double check video card performance before your purchase
Look at previous generation cards
Always check the minimum requirements for the game

Wireless Network Basics

If you've got more than one computer at home, you may be thinking about setting up a wireless network. It can make file-sharing a breeze, with no more having to burn data onto a CD-ROM or trying to fit it all into a memory stick (or -shudder- a floppy disc!) to get it across the room. And going wireless lets you position the router in a convenient central location, without having to run wires along the baseboards or under carpets.

But setting up a wireless (or 'wi-fi') system can be a daunting task if you've never done it. Or is it? With technology today, firing up a wireless router and adding a few access points has never been easier. Many of the setup routines are automated, with your input limited to thinking up a few passwords, or typing in some information off the label on a piece of hardware. Let's take a quick look at some of the hardware common to any wireless setup.

The core of any network is the router. If you already have a broadband/ADSL/cable modem, it's best to get one with the modem function built-in, and replace your existing one. If you don't want to do that, make sure the router you decide upon can be plugged into your modem. The router transmits and receives the signal to your computers. Almost all of them have several Ethernet ports to connect devices with a cable.

This is handy if you have a computer or network-accessible printer nearby, and don't need a wireless connection. The important thing to remember when purchasing a router is to make sure it's 802.11g compatible. The 'g' means it's faster than the older 'b' standard. You may see references to an upcoming 'n' standard as well. The final requirements for this standard have not been fully decided as of yet, so if you get a 'pre-n' piece of hardware, the standards may change, leaving your device unable to function properly.

Your computer will need a wireless access point to communicate with the router. There are two main types. The first is the PCI wireless network card. This is an internal card, like many modems, and must be installed inside the computer in an empty card slot. These will have an antenna that sticks out of the back of your PC, which may not give you the best signal if the antenna is hidden away. Some models have a short cable for the aerial, so you can mount it somewhere to improve reception.

The second type of network connection is a USB adapter. This attaches to an open USB port on your computer, and has either a built-in antenna, or a cable to a separate aerial, like the PCI card. These are portable between computers, but may not receive as well as a built-in card. Also, they can be bumped if they stick out of your computer.

If you have a notebook computer, many of them now have wireless access built in. Older models can use a notebook card, which slides into the PCIMCA slot.

With this basic knowledge, you may find that configuring your own wireless network is amazingly easy. In no time, you can be surfing from anywhere in your house, or passing files back and forth effortlessly from one computer to another. Many other devices can now also access your home network, such as game consoles, cameras and cell phones. Unplug yourself, and see how much fun it can be to go without a wire.

Notebook As A Tool Of Time Management

Notebooks have emerged as a bare essential for the business executives who carry their work along with themselves. Notebooks which are also known as laptops can facilitate the work process thereby saving substantial and valuable time. In short, it is used as tool of time management.

Owning a notebook is a dream of many, but since it is very expensive nobody buys it unless it is indispensable to them. However, some people having shoe-string budget look for a good notebook. They are the ones who need detailed and comprehensive information on notebooks and laptops before they settle for one.

Basically, buying a notebook or laptop largely depends upon the personal choice, specific requirement and social status of a person. Besides, different manufacturers are introducing notebooks of different look with a wide-range of features. However, some notebooks are launched in the market to cater to a particular segment of buyers keeping in mind of their specific needs. Accordingly, these laptops differ in flavor, class and quality.

Let`s take a look at the various types of notebooks that are available in the market today. Keeping various factors in consideration the notebooks can be broadly divided into four major categories, such as:

Budget laptops - Typically, these laptops cost around US$ 1000 to $ 1200.

Mid-range laptops - Notebooks of this category can be found with a price-tag of about US$1200 to $1600.

Ultra-portable laptops - These light-weight laptops ranges from US$1600 to $2200.

Laptops for the people with a class apart. With all the standard and advanced features in these notebooks, they cost above US$2200.

Performance test of laptops:

Notebooks can be tested on the basis of certain benchmarks such as Multimedia content creation 2003 and Business Winston 2002. These tests determine the performance ability of different notebooks with regard to regular productivity applications and multimedia content application.

Similarly, 3D Mark05 and 3D Mark06 are used as standards to measure the gaming and graphic potential of different notebooks.

Likewise, PC Mark05 is taken as a yardstick to test various components of notebooks such as hard-disk general usage, multithreading, web-page rendering, file decryption and 3D pixel shader.

Moreover, the battery back-up and wireless connectivity can be tested using Battery Mark02 and QCheck as the benchmark.

Finally, Vista Compatibility Check can be undertaken to test if the notebooks have Vista-readiness. Under this test, the performance of the laptops is assessed on the basis of Vista drivers and Vista upgradeability.


When it comes to features, the list seems endless. Some expensive notebooks have the most advanced features such as built-in webcams, fingerprint readers, TPM and so on. So far as the features go, they can be divided into five different categories, such as:

Physical - Screen size and weight of the notebook

Connectivity - Bluetooth version 1/2, infrared, MMC reader, S-Video, DVI port, FireWire. The number and type of USB ports and PCMCIA slots.

Components - Type of optical drives, whether the notebook has a DVD combo, a CD-RW or a multi-recorder DVD-RW. The hard-drive capacity and any additional component such as wireless optical mouse or an MMC adapter.

Software - Software have always been an essential part of the package. These include recovery CDs, driver CDs, OSes, etc.

Protection - All types of protection available in a notebook, be it a finger-print reader, BIOS level HDD protection, touch-pad lock, TPM, or even rescue option available at the time of boot up.

Pricing and Warranty:

All notebooks ranging from $1200 to $4500 offer warranty of 1 year and some laptops have the option of additional extendable warranty.

So, the above discussed comprehensive analysis and performance tests will definitely help those who are planning to buy a laptop.
