How to Treat Hard Drive Failure and Data Loss Circumstances

Data loss is something very critical and could occur any point of time. Data and information is the most important assets for any organization and it is required for proper functioning of the business. When data loss occurs, grave situations might take place and you need to go for Data Recovery solutions to retrieve lost data. It is the process of salvaging lost, missing or inaccessible data from a damaged, corrupted or unusable storage media that can not be accessed normally.

Data loss could occur from any sort of storage media and could be recovered from all of them including hard drive, storage tape, RAID (Redundant Array of Inexpensive Disks), SAN (Storage Area Network), NAS (Network Attached Storage), CD and DVD. The recovery is generally required when any storage media gets damaged either physically or its file system face logical damage or corruption.

The restoration or recovery results into proper accumulation of files by the operating system. Before the recovery process becomes difficult, you are recommended to create a valid backup of your mission critical data. The backup enables you to appreciate the concept of recovery.

Failures that require recovery:

• Operating system failure: It is a very common problem, which requires recovery using appropriate tools. It generally occurs due to improper system shutdown, virus infection like situations on single partition hard drives. This type of failures are put in logical failure category.

• Hard drive physical failure: Such type of failure and data loss situations occur due to damage to the internal components of hard drive. This kind of damage is quite difficult to handle and require advanced tools to be resolved.

• Hard drive logical failure: This type of failure occurs when the disk data structures like file system, partition table, boot record, boot loader and many alike. These cases are quite easy to be fixed as compared to physical failure.

Hard Drive Recovery in case of physical failure is possible with the help of recovery service. It is a personalized and sophisticated help, which is delivered through Clean Rooms by skilled and experienced recovery processionals.

On the other hand, logical data loss situations can easily be tackled with disk recovery software. These are easy to use and advanced applications, which are capable of handling most of the data loss situations. These Partition Recovery software are complete safe and easy to use.

Stellar Information Systems Limited offers superior recovery solutions to handle all sorts of data loss situations. The service is carried out for IDE, EIDE, SATA and SCSI hard drives in Class 100 Clean Rooms. Software are available for Windows, Mac OS, UNIX, Linux and Novell.

NiMH Batteries in a Nutshell

NiMH is the abbreviation for Nickel-metal hydride batteries. These are known as the secondary or the rechargeable type of electrochemical devices. They are very similar to Nickel hydrogen cell. The only difference between the two is that instead of cadmium, hydrogen is used as the active element in NiMH batteries at the negative electrode. NiMH batteries were first introduced in the market in 1989. A NiMH cell offers an operation value of two to three times higher than the equivalent size Nickel-cadmium battery. These cells provide an average output voltage of 1.2 Volts.

The working of the nickel-metal hydride cell is based on the simple concept developed in 1970s. It was observed that certain types of metallic alloys were capable of capturing and releasing Hydrogen in volumes thousand times their own. This research demonstrated that stored hydrogen could be used as an alternative source of energy. Further experiments were carried out using differing proportions of alloy constituents to balance the thermodynamic equation during the absorption and release process, under room temperatures and pressures.

The technology has greatly evolved since then and today the NiMH batteries have found its utility in high voltage automobile applications. These cells have an energy density twice that of Lead acid and nearly 40% higher than that of NiCads. Although the NiMH batteries are a little expensive, they are considered to be better for the environment.

Owing to the several advantages offered by the NiMH batteries almost every specialized automobile under production today makes use of them. In order to meet this increasing demand, many leading companies have a specialized R&D department devoted to the development of high-performance and superior quality NiMH batteries. Some brands of NiMH batteries have gained high reliability among the consumers and are widely used in EV/HEV and other places like the scooter, e-bike and motorcycle.

Steps to Ensure Successful Data Recovery

We store a lot of information on hard drives are other storage devices that is very important to us. We can have important work files, personal work that could take months to re-do and precious family photos and videos. So when data loss occurs it is understandable that many people will panic when they don't have a back up. It's not the end of the world though, data can be recovered.

Take the following steps to ensure that you are able recover your important data. To avoid permanent data loss it is important you follow these guidelines:

1 If you hear strange whirring, grinding or clicking sounds, shut down your computer immediately. Severe or complete data loss could occur as the heads in the drive could be hitting the platters that store the data.

2 Take care and unplug the computer before removing the hard drive. You have to be very careful when handling the hard drive as physical jolts can cause damage and are sensitive to static electricity.

3 If your have critical data you want to recover then make sure you choose a well known recovery firm or one recommended from a friend or colleague. Even simple attempts to recover a physically damaged drive can end in making it completely impossible to recover data anymore.

Remember the first recovery attempt offers the best chance of recovery. If you have very important information, don't take the risk, pay a professional so if there is a chance to recover the data; they will be able to do so.

When problems happen:

1 If it is possible, back up the data straight away

2 Don't power up any device that has been making strange noises or clearly has physical damage

3 Don't use utility software if the hard drive is making clicking, humming or tapping noises.

4 As soon as you notice any symptoms of hard drive damage shut down the computer immediately to avoid further damage.

5 Finally don't attempt to recover the data yourself for severely damaged machines as the system will be very vulnerable, any attempts to recover can spell permanent data loss. Seek professional advice for data recovery

Apple Tablet how it look like in your workstation

There's a lot of speculation about the Apple tablet, but coming November, this is how my desk is going to look. Or at least, this is what I want. Check it in super high definition after the jump.

Click on the image to enlarge. Yes, this makes me wet.

That, my friends, is what I think we are getting.

The Apple tablet I want will run the same basic hardware as the iPhone, with extended video and system RAM to accommodate larger computing needs, perhaps with some limited multitasking for some applications. System RAM is a big system bottleneck right now, and it won't cost much to add enough to make things flow smoother. The video RAM will be necessary for the higher res of the 10 inch screen. The current iPhone CPU and graphic processor can handle all this well as they are. No need for changes. It will also be very thin. As thin as the iPod touch. Since its guts will be the same, but it will be a device with a larger surface, you also have more space for a larger battery.

Why do I think it will be this way? I believe the hardware will be dictated by economies of scale, which has been the norm since Jobs returned to Apple: Reusable components across each product family to keep costs down. In this case, the product family—which Jobs already alluded to in the past—is the iPhone OS-based product family. Right now, there are two products, as you know: iPhone and iPod touch. My wish is that iTablet or whatever it's called will be the third. That way, Apple would be able to build this cheaper—and keep the cost of the iPhone and iPod touch down if the tablet is successful.

Logically, the iTablet I want will run exactly the same OS as the rest of the product family. The OS will have the same kernel, the same classes, the same subsystems, the same database organization and the same file system. It will also have some new extra apps, and perhaps a few new gestures—which will trickle down the product line—but that's about it.

It will run the same applications, changed to accommodate more information thanks to the higher resolution in the screen. Some Apple and third-party ones will be tailored to the higher res, distributed in a package that will have both iPod-sized and tablet-sized graphic assets. Others—like Safari or games—will just enjoy the instant boost in resolution.

And that will be the beauty of it.

First, people who are afraid of computers—probably not you, the typical Giz reader, but most consumers out there—will love this device as much as they love their iPhones or iPod touches. Apple will keep mining the gold, and offering consumers this extremely easy-to-use interface that doesn't require any mental abstraction. Just click, touch and access the information, media or games you want, mixed with the occasional short mail or chat.

For developers, it's also a win-win situation. Same code, just add new assets. Same store, same distribution, more development opportunities.

The way I see it, the tablet will open the way to a new kind of computing, after the ages of computing for hobbyist, the age of the command line, and the age of the desktop user interface metaphor.

To me, this is where Star Trek starts, and War Games ends.
