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.

The term Notebook computers and laptop computer is often used interchangeably. However notebook computers are smaller, lighter and costlier than laptop computers. You can carry this computer with you when you are away on a business trip, can watch movies and access internet also.

The first notebook computer which was launched in the market in 1981 was expensive and was not as versatile like present day computers .Portable versions of laptops were launched in the market by IBM and Epsom in 1983.

With introduction of Windows 95, the world of notebook computers took a giant leap forward and was now able to compete with other personal computers because of the operating system and the advancement of technology. Prices of these computers started falling, attracting more consumers. Life of battery improved and acids were no longer required. The notebook computers now consumed less power and could hold more data.

Notebook computers come in various sizes. For a quick reference, have a look at the following figures (without power adaptors and accessories): Tablet PC - it weighs less that 3 lbs; Ultra Portable - it weighs less than 4 lbs and less than 1.3 inches thick with size between 10 and 11 inches; Thin and Light - it is between 1 and 1.4 inches thick and weighs between 5 to 7 lbs with size from 11 to 14 inches; Desktop replacements (Largest) - it is 1.5 inches thick and heavier than 7 lbs. Size between 11 and 13 inches.

Some important points are listed here which may help you to have an informed purchasing decision:

Size and Weight: The point to remember that while choosing a very lightweight and small size, you may have to sacrifice some items such as drives. So you have to decide what you want.

Processor: Note book processors perform like desktop processors. Dual core processors carry multitasking and are common. Notebook processors directly impact the battery life and performance of the computers. For Intel premier processor, higher the number, the faster it will process. The rotational speed of the disk also affects the performance of these computers.

Memory (RAM): For Windows XP and Mac OS X, at least 256 MB is required. However the capacity of RAM is increasing with new varieties of notebook computer and in some machines it is 2 GB even!

Displays and Video: In a notebook computer video consists of video processor and display. Again the display consists of native resolution and screen size. But portability will be reduced with larger display. These days the popularity for the wide screen displays is increasing. Performance of PC gaming and 3D graphics will be determined by graphic processor.

Drives: Optical drives play an important role in notebook computers. These may be simple CD ROM drives to the high definition DVD burners. Most notebook computers these days are equipped with a dual layer DVD burner.

Connections: Wireless Fidelity (Wi-Fi), 802.11a, 802.11b and 802.11g, Fujitsu lifebook N6010 having trimode of 802.11a/b/g, etc are different wireless system available with notebook computers. Transferring rate of data depend on the type of wireless connection chosen.

Battery Life: Notebook computers come with four cell, 6 cell, and 8 cell batteries. Normal battery life is 2 to 3 hours. However 5 or 6 hours battery life is also available these days. Generally, the bigger the notebook computer, the lower is the battery life.

Warranty Plans: Make sure that you get at least one year warranty from the manufacturer while choosing your notebook computer. A system having a three year warranty will be a better choice if you are going to use your computer extensively.

It is suggested that you should update your knowledge periodically by logging onto the net keeping in mind the factors which need to be checked as stated above.

Apart from the heatsink and the heatsink fan, your computer comes equipped with at least two internal fans. One fan draws in outside air to help cool off your internal computer components, the other fan ejects hot air outside of your computer case.

If your computer is running hotter, one of your internal computer fans may be malfunctioning. Another way to tell whether there is a problem with your computer fans is by the amount of noise that they make. A noisy fan may be as bad as it sounds.

Before you go all out and replace your computer fans in an on-the-spot PC upgrade, try cleaning the fan to fix the problem first. Sometimes, dirt prevents your fans from performing its cooling duties efficiently. If your overheating problem persists, then you really need to consider your available options of replacement fans.

If you are using high-end computer parts, you should seriously consider installing extra cooling fans inside your computer case. Fast-spinning hard disk drive, graphics cards and the processor all give off a lot of heat when you are running resource-draining programs and applications. These computer components will need more than the normal heatsink fan and two standard cooling fans to help them cool off.

A fast-spinning fan naturally makes a lot of noise. If you are concerned about the noise that your computer fans make, buy a larger fan that spins at a slower speed.

After you get your replacement fans, make sure that you set them up properly. The fans should efficiently guide air around your case. Cool air needs to come inside at one point, be swirled around the case by your extra fans, and finally, be guided outside one side of your case. You may have to do some case modding to make room for the extra cooling fans, but their benefits will make it worth your while!

Refurbished laptops are becoming popular among consumers as the savings over purchasing new laptops continues to become a bigger factor in today’s economy.

As a recent article shows, virtualization is taking over in a big way. This technology allows better use of system resources by allowing multiple operating environments on a single physical hardware platform. More specifically, it is the creation of one or more virtual instances of a “guest” operating system on top of a “host” operating system, or in some cases directly on top of a specialized software layer. It allows numerous virtual machines, either standard PCs or servers, to operate and appear as independent machines when in fact they’re operating off of a single hardware platform.

Many software providers from large to small are in the race to offer virtualization solutions, and many enterprises are taking advantage. While this futuristic technology certainly offers many benefits, it has one critical challenge to its overall performance–disk file fragmentation.

File fragmentation–the splitting of files into pieces (fragments) in order to better utilize disk space–is a performance challenge in non-virtual environments, and has been for many years. But virtualization brings with it even more critical fragmentation issues, requiring solutions like never before.

The key to understanding fragmentation’s impact on virtualization lies within the word “virtual” itself. For storage, virtual machines are making use of hard drive partitions which appear as entire drives dedicated to the virtual machines. But underneath the “virtual” layer, the hardware is storing files the way it always has, utilizing an entire disk and fragmenting files from all partitions across the whole disk.

Virtual machines have their own I/O requests which are passed along to the host system. Hence, multiple I/O requests are occurring for each file request–minimally, one request for the guest system, then another for the host system. But in a common fragmentation scenario, especially with virtual servers creating high amounts of disk activity, files will be fragmented in to tens, hundreds or even thousands of fragments. Imagine the frantic activity with multiple I/Os for each fragment of each and every file requested. The impact on performance is horrendous.

With virtualization, regular defragmentation is vital–but so is the fragmentation technology utilized. Basic defragmentation, even scheduled defragmentation, cannot possibly keep up with the fragmentation rates of virtualization. The best possible solution, one which is only now becoming available, is a constant background defragmentation solution which has no impact on system resources.

Additionally, defragmenters exist which offer additional technologies which add benefit specifically to virtualization.

The moral: when implementing virtualization, make sure you also implement a robust defragmentation solution which will keep up and allow virtualization to deliver the intended performance gain and resource savings.

Fiber optic pulling eye is also called cable pulling eye. It is a device that is fastened to a fiber cable. The hook can then be attached to the fiber pulling eye to pull the fiber cable through a innerduct, duct or small space.

Alternatively, it is possible to simply tie the pulling rope to the strength member in a fiber cable. This is enough for very simple pulls with very low resistance. But for conduit runs, this is a dangerous practice since the knot may catch along the path and fiber may be broken.

 

The cable pulling eye approach is a common and recommended practice for most fiber pulling jobs. Here are the general steps with this method.

 

1. Strip the cable to expose about 15cm of cable strength member only

2. Cover the strength members with epoxy glue

3. Fill the pipe section of a pulling eye with epoxy glue and fit it to the strength member. Allow the epoxy to set before starting pulling

4. Cover the end of the fiber cable with tape to ease the transition between strength member and cable. This protects the fiber cable and also stops ingress of dirt or water

5. For long cable runs, use intermediate pulling points where the cable is pulled through and coiled up in a figure “8″ pattern on the ground and then fed into the next conduit section

6. At intermediate pulling points, reapply cable pulling lubricant to the cable before pulling through the next conduit section

 

Another popular method of attaching a pulling rope to a fiber optic cable is the “Chinese Basket” or “Kellems Grip”. This is most effective with larger diameter cables.
