Little-known Strategies to Maximize the Life of Your Hard Drive

If I asked you the question: which part of your computer is the most fragile, what would you say? What if I asked: which part is most important to you?

Often, the answer to both of these questions is your Hard Drive. Your hard drive is likely one the most important things you own. It contains work data, school data, emails, photos, music, movies, tax information, etc… Incidentally, the hard drive is also one of only two moving components in your computer (the other being your optical drive). The following is a list of important maintenance and monitoring techniques you can use to maximize the life of your hard drive and prevent data loss.

Hard drives are physically fragile – handle with care. Statistics show that 25% of lost data is due to a failure of a portable drive. (Source: 2001 Cost of Downtime Survey Results)

Contrary to its seemingly rugged appearance, your hard disk is a very delicate device that writes and reads data using microscopic magnetic particles. Any vibration, shock, and other careless operation may damage your drive and cause or contribute to the possibility of a failure. This is especially relevant for notebook users, as they are most at risk of drive failure due to physical damage, theft, and other causes beyond their control. That’s why we recommend regular backup of notebook hard drives, as often as possible.

Possible solutions include external USB or Firewire drives (although these are prone to the same risks), desktop synchronization, or backup at a data center through the web.

Hard drives write data in a non-linear way forcing it to become fragmented. When files accumulate on your hard drive, they do not just get written in a linear fashion. A hard drive writes files in small pieces and scatters them over the surface. The fuller your hard drive becomes and the more files you save and delete the worse file fragmentation can be. Hard drive access times increase with fragmentation since your drive must work harder to find all the pieces of the files. The more fragmented your data is, the harder the actuator arm has to work to find each piece of a file.

A case in point: Disk fragmentation is a common problem for users of Outlook Express and database software. Each time outlook saves new mail, it does so in a different physical location from the previous time. This results in extreme fragmentation, causing longer hard drive access times and forcing more strain on the heads. This strain can eventually lead to a head crash, and often that means a virtually unrecoverable drive. Finally, in the event of a total crash, a fragmented drive is much more difficult to recover then a healthy defragged drive.

Luckily, Windows makes it remarkably easy to defrag your hard drive, simply launch the Disk Defragmenter utility (Start > Programs > Accessories > System Tools), choose which disk or partition you’d like to defragment and set it to work overnight or while you are not actively using your computer. Defragmentation will speed up your computer and ensure a longer life for your hard drive.

A very small power surge can fry a hard drive – use a UPS and turn off your computer when you can. Another little-known fact about the fragility of your hard drive is its susceptibility to electrical failure. An electrical failure can be caused by a power surge, lightening strikes, power brown-outs, incorrect wiring, a faulty or old power supply, and many other factors. If a power surge enters your computer, it may do an unpredictable amount of damage, including destroying your hard drive’s electronics or crashing the heads and possibly resulting in total data loss.

The best way to protect your computer from such dangers is to use a highly rated protected power bar or an Uninterruptible Power Supply (UPS). Although these devices won’t eliminate the chances of a crash, they will serve as effective protection in most cases. Also, you can minimize the danger of an electrical problem and reduce wear of your hard drive by turning off your computer or using power-save modes whenever possible. It’s a known fact that 100% of drives fail, the question is when will it happen and will you be prepared? Make sure to check out the knowledgebase section of our website for more detailed information on how electrical power affects your computer. Be SMART, monitor the health of your drive to prevent unexpected crashes.

All modern hard drives have a self-monitoring technology called SMART (Self Monitoring Analysis & Reporting Technology). What most people don’t realize is that the majority of hard drive failures do not have to be unexpected. Most failures occur as a result of long-term problems which can be predicted. By regularly monitoring disk health and performance, you can know about potential hard drive problems before you lose any of your data.

Several excellent utilities are available, including DiskView and Stellar SMART for standard IDE and SATA desktop drives. Also available are tools that monitor the health of SCSI drives and full RAID Array systems. Ariolic Software offers a great utility called ActiveSMART.

The only fool-proof way to prevent data loss is... Backup! If you only take one of the suggestions here to heart, let it be this one: always back up your important data. After all the monitoring and all the prevention measures are in place, one fact still remains: all hard drives fail. Backing up regularly will ensure that you’re never caught without your critical data. For individuals, the simplest solutions include external portable hard drives, dvd’s, and online storage. For businesses, we recommend renting space at a secure data centre and implementing a disaster recovery plan, regardless of the size of your business.

I hope that the above techniques give you some idea of the importance of hard drive maintenance and provide some insights in how you can protect yourself from data loss.

If your hard disk crashes, is your data covered by any warranty?

This was a question that was recently put by forward on a TV consumer show. One guy had his hard disk crashed and lost all data. He was able to get his hard disk replaced because of a warranty.

To retrieve the data he had it sent to a data recovery company to get it recovered. The price tag was about $ 1500. But, he also wanted to have that extra cost covered by the same warranty.

I’m not a lawyer, but I believe it is quite clear that any warranty from any hard disk manufacturer doesn’t include restoration of data. That said, with the long life time and high durability of today’s hard disks they could very well afford this when it is caused by a hard disk failure.

As long as the hard disk only have a mechanical or electronic fault and it have not been exposed to water or fire the track record for restoring the data by a professional data recovery company is quite good. However, you have to expect to pay a chunk of money to have it restored. And you can never be 100 % sure they will succeed.

It’s always worthwhile to backup all your data or at least backup the data that is most important for you. This is the best warranty against data loss.

If you use the computer for leisure, playing games or surfing the Internet you may not need to take any backup at all. But today, more and more people store important document and information on their computers. Some store data vital to their professional life. This can be years of work such as academic thesis or it can be the content for a new book they are writing. Most people store at least some important information such as address books, emails, text documents, family pictures, music or company records.

Should you take backup? If so, what type of backup is best for you?

This all depends on:  The value of the data if it becomes lost. The time it will take to recreate lost data. The cost to make the backup.

In most cases the data you need to backup are limited to specific files or folders. If that is the case you don’t need to backup the complete hard drive and the cost to make backup is reduced. If you only need to backup documents, emails and address books then there are many cheaper alternatives including USB flash memory keys, online backup or backup to CD’s/DVD’s.

If you install important software from Internet then you need to take a full backup of the hard disk at least once. This is because nearly all software programs store system related information in what is called the reg keys deep in the operating system which must be backed up on a full backup.

As an alternative, make sure that you save the installation files and any accompanied software registration keys in one specific folder after you have downloaded the software. If you do this and include the folder in one of your regular smaller backup, then you are capable to recreate it.

If you get a hard disk crash and you want to minimize the downtime and you don’t want the hassle to install the operating system and all the software’s you have on installation CD’s. If that is the case then you should consider making a disk image backup.

This is a backup of the complete disk drive. Included in the disk image software is a boot utility. From it you can create boot diskettes or boot CD's.

Thus, if you hard disk crashes you first install a new hard disk. Next you boot up from your diskette or CD. From the boot program you are then able to create your disk image directly on the new hard disk. So by doing this type of restoration you don’t have to install the operating system and all you other programs from any installation CD’s. This saves you time.

How to Choose Right PC Diagnostic Software

Computer Diagnostics is a need to keep a healthy operating system and vital for business productivity, where a failure can be a costly mistake. PC diagnostic software can determine hardware and software conditions and possible failures, as well as current settings and connectivity.

A PC diagnostic program can also suggest the best performance settings in order to get the most of your system according to your hardware specifications. In addition, a PC diagnostic tool can help you to identify potential problems that can damage your hard drive or any other piece of hardware.

Some companies provide troubleshooting tools to test your PC’s electronic circuits, in the form of system plug-ins or stand-alone applications. Computer Diagnostics should also be able to check other computer components such as the BIOS, serial and parallel ports, USB and Ethernet ports, etc.

Choosing the best PC diagnostic software depends on your computer related knowledge. You may find a PC diagnostic program worthless if you do not understand what a benchmark diagnosis means, or cannot make changes in the settings that the PC diagnostic tool may suggest.

Computer Diagnostics provide end user with intuitive diagnostics tools for troubleshooting while improving performance. However, some of them can be risky if you do not understand what they can do, like those including the ability to reformat any type of hard drive.

Most software developers state, "use it at your own risk" because of the lack of knowledge that can lead also to massive data loss. Although data can be recovered, it is a painful process because of the required proper software or you may have to take the hard drive to a service center that can restore and reformat your hard drive.

Even then, there are no guarantees of getting 100% of your data back, so be careful choosing software intended for Computer Diagnostics, and always read before clicking any "OK" message that may pop up.

If a PC diagnostic tool returns the parameters of the hard drive, and allows toggling the IRQ directly to determine which I/O port is at which IRQ, make sure you understand what all this means before proceeding, because the software can read, write, overwrite and edit most values.

Perhaps the best PC diagnostic software is that which can only read, generating log files or an overall detailed report of your computer including all its components.

If the PC diagnostic program cannot write, the possibilities to damage your hardware or destroy your content are very low, although other problems such as a buggy, unstable version can ruin your operating system.

How to recover lost photos


 It happens all too often. You're downloading your latest snaps from your digital camera, and the computer freezes. After you restart and try again, there appear to be no pictures in the camera. Or perhaps the photos were on your hard drive and you deleted them accidentally, or you didn't have a backup and your hard drive failed.

Whatever the cause, there is no reason to panic. The computer may no longer be able to find your pictures, but it's unusual for a fault to completely wipe them from the storage card or disk. With the aid of some inexpensive data recovery software, you're almost certain to be able to get your photos back.

There are many data recovery programs on the market, but for photo recovery I strongly advise using software specifically designed to recover digital images. This kind of software has several benefits, not least the ability to show a preview of every recovered image. Often, data recovery tools find files that look like they might have been a digital image, but aren't. The preview feature saves you wasting time recovering files that turn out to be junk.

Another advantage of specialised photo recovery software is that it looks only for photo image file types. It knows what JPEG and other image files look like on disk. This improves the chances of a successful recovery, and reduces the number of junk files that are found.

Modern data recovery software is easy enough to use that anyone can do it. You just start the software and tell the program where the drive containing the missing images is. The software scans the drive looking for the patterns that it recognizes as photo image files. When it has finished, it will display a list of files, with thumbnail images showing the content. All you have to do is select the photos you want to recover, and safe them to a safe place on your hard disk.

Incorporate a disaster recovery plan

Nordural ehf's backup system needed to incorporate a Disaster Recovery plan that would reduce the backup window from ten hours to two-three hours.

A Disaster Recovery Plan is a coordinated activity to enable the recovery of IT/business systems due to a disruption. Disaster Recovery can be achieved by restoring IT/business operations at an alternate location, recovering IT/business operations using alternate equipment, and/or performing some or all of the affected business processes using manual methods.

It was essential that Nordural's backup system incorporate a trustworthy Disaster Recovery plan that would reduce its backup window from ten hours to two-three hours. In addition to this, Nordural wanted a Disaster Recovery plan that restored the company's most critical servers to bare metal restore in less than two hours.
Nordural's decision to select the SecurStore Remote Backup Service highlights the strength and flexibility of managed services. 

Remote backup (sometimes also referred to as online backup) is a service that provides users with an online system for backing up and storing computer files. Remote backup service providers are companies that provide a software program and space on a server that their client's data is stored on. The software program will run on a client’s computer and (typically) once a day; compress, encrypt and then send the client's data to the remote backup service providers' servers to be stored.

With SecurStore, Nordural had the assurance that all their requirements would be met - from a fast critical restore, to remote backup at multiple locations, to a simple and effective interface for the IT people at Nordural.

"We chose the SecurStore Remote Backup Service because it gives us all round backup and recovery services for our needs, with 24x7x365 support" said Emil Hilmarsson, IT Manager Nordural. SecurStore also provided Nordural with the option of assigning which data is 'critical; and which is 'important' data by using Long Term Storage with the use of Backup Lifecycle Management system that manages data during all backing up and archiving processes.

Backup Lifecycle Management differentiates data into varying levels of protected data: current critical data, which is stored on-line for fast recovery; and archivable data that may be needed at a later time but is not likely to be accessed in the near future.

Alexander EirĂ­ksson, President of SecurStore, confirmed, "The agentless architecture of SecurStore Remote Backup Service allows us to implement the service with minimal interference to Nordural's existing computer systems. Moreover, because the service is pivoted around providing backup and recovery for geographically dispersed locations, it perfectly compliments Nordural's multi-site locations, remote or otherwise. This provisioning enables Nordural to remotely back up laptops even when workers are away."

At each customer site, a single client discovers all servers, desktops and laptops connected to the local network, and automates the backup of all local data assets.

How To Recover Lost or Deleted Data Files: Data Recovery Software Information

Have you heard of data/file recovery? The definition of the term Data Recovery is "Making previously lost or damaged data available again." A data recovery software or method can help us recover destroyed data e.g. an accidentally deleted file. It happens all the time. You delete an important file on your PC and send it to your recycle bin by mistake. You realize what you've done only after you've cleaned the contents of the recycle bin.

What do you do now?
That file you deleted was so important. Fortunately there are lots of methods (Data Recovery Methods) and software (Data Recovery Software) available to help you get your lost files back.

Let's start by mentioning some possible reasons for the loss of data:

* You accidentally delete an important file. Then you immediately shred the contents of your recycle bin
* During today's system crash some files just disappeared and cannot be located or accessed
* You format your hard drive but then you remember those important .zip files previously stored in the newly formatted empty medium.
* A power outage prevented some files from being written to the hard disk.
* Data loss can also occur due to physical damage of the storage media. For example the surface of your CD-ROM may be scratched off or your hard disk may suffer from all kinds of possible mechanical failures.
 
Is Data Recovery Important?
Data recovery is a very misunderstood concept. A lot of people may not even be aware of the existence and the importance of data recovery. Maybe they think of it on a personal level. The truth is, lost data causes financial disasters to companies all over the world. The cost associated with computer downtime and lost data is enormous (several million dollars) for businesses.

How to deal with data loss?
Losing files is easy but recovering them can be difficult. If the loss was due to physical damage then you need someone with experience, a hardware technician or something. It wouldn't be wise to try to overcome hardware failures alone unless you are a professional.

Now, if the loss of data was due to logical failure or human error then the solution is data recovery software. The data recovery software should be able to:

- Undelete files even after you've shred the contents of your recycle bin
- Recover files after you've been infected from a malicious threat (trojan, worm or other virus)
- Recover files from reformatted hard disks or after your system crashes or your hard disk fails
- Recover all types of files (all kinds of documents, images, music, videos, email messages, zipped files etc)
- Recover data from all types of storage mediums (hard disks, external drives, CD-ROM, usb drives, floppy disks etc)
- Recover files easily and successfully. Should be user-friendly allowing someone with no data recovery skills to use it
- Take/create backups of critical system files or files you choose

The best way to avoid data loss is to start taking backups of your important storage mediums. Either create backups of data on CD-ROMS or use an external drive or zip drive to back up your critical files. If you want to go further look for software that automates the process of backing up and storing your data. These programs are kind of "set and forget". You set it up to take backups every hour or every day or month etc. and let the software do the rest.


How to recover deleted or lost files

It's a sickening feeling, the moment you realise that some important document, or irreplaceable photos have vanished from your computer. But that is no reason to despair. The chances are that the data is still present, even if you know you deleted it. Your computer operating system just does not know how to find it any more.

The four most common reasons for data loss are:

    * Deletion. You deleted the file by accident during a disk cleanup, or because you thought it was no longer required. It is not in the Recycle Bin. However, the data will still exist until the space it occupied on the disk is are-used by another file.
    * Overwriting. You saved a new file over the top of the old one. However, the old data may still exist, and be recoverable.
    * File system corruption. The disk suddenly appears empty, or the file and folder names contain gibberish. The files probably still exist, but the pointers to them have been lost or corrupted and the operating system cannot find them.
    * Physical damage or hardware failure. You receive error messages when you try to read the disk, or it is not recognised by the computer at all. The data is still likely to be present on the disk itself, but the drive is incapable of accessing it.

In each case, there is a good chance that the data still exists. The computer operating system isn't able to see it, but data recovery software may be able to. If the problem is a hardware failure then a data recovery service may be able to get back the data using special equipment.

Prepare for data recovery

There is one cardinal rule of data recovery: for the best chance of recovering the files you must not write any new data to the disk they were stored on. The old data will only remain on the disk until the space it occupied is used by another file. If the disk is your computer's main drive, then the drive is being written to all the time. You should turn off the computer immediately, and use another computer to search for a solution to recover your data. You should put your computer's hard disk in another computer to do the data recovery, or use data recovery that runs from a CD or floppy disk, because installing the data recovery software on the drive could overwrite the very data you want to recover.

Choosing the data recovery method

Data recovery tools use different methods to try to recover data. Some tools are designed for recovering deleted files, others are better at restoring overwritten files, or recovering files from disks that are physically damaged. Some data recovery software products have been developed specifically for recovering photo images, or Microsoft Word or Excel document files. Such products may succeed where others fail because they understand what these files look like, and can recognise their data when other clues to its existence have vanished.

It can be difficult to choose the most appropriate data recovery method. Tech-Pro has created a website called Get Data Back. It has a Data Recovery Wizard that asks questions about the data you have lost and how it was lost, and then recommends the product that is most likely to be successful. It will also advise you if it would be better to use a professional data recovery service. Give the Get Data Back data recovery site (http://www.get-data-back.com) a try if you need to recover lost files.

How To Recover Lost Data

Computer files are a lot more important to some people than their lives because it represents their whole life’s work and achievement. There are people who rely on their computers for almost everything, from their daily schedules, business and personal files and what have you. The possibility of losing their computer data is thus a horrifying thought for them.

Even a student who uses his computer to store assignments, research papers and other school data will be dismayed at the though of losing such files. What more for a computer dependent entrepreneur who relies on his computer for the day to day existence of his business. Losing computer data for both types of computer users would mean a catastrophe because once lost, computer data can no longer be recovered.

However, technological advancements have made data recovery possible depending on a lot of factors. For one, computer users are advised to make back ups of their computer data to make sure they would not be caught red handed when computer data is destroyed. For some who hold very important computer data, the back up itself should even be further backed up to make sure there is a way of recover lost data.

Fortunately, there are companies who offer data recovery services in case of an unforeseen disaster like corruption of files or crashing of a computer hard drive.  People who store very important data in their computers need to have back ups but in any case, they should be acquainted with a computer company that can offer them fast and efficient services for the recovery of their lost computer data.

It is thus pertinent that computer users have a way of knowing where to contact computer companies who can recover lost data for them no matter how such data was lost. There are various ways of losing precious data and one of those is carelessness. People take for granted that computers are very fast and efficient machines they can accidentally command their computers to lose or delete data in a flash.

The widespread use of internet has also been responsible for thousands of computer crashes all over the world because of viruses that attack computer hard drives. There are plenty of technical reasons why data is lost. Added to that are unforeseen disasters like fire or other calamity.

Computer users who have backed up their lost data but who discover that their back ups do not work still have a recourse. Rest assured that there are companies and software that can recover your computer files efficiently and quickly to minimize your potential losses.

Companies providing data recovery are equipped with technical people who around the globe and are more than capable of bringing back lost data. You just have to be able to know them beforehand so that when your computer data gets lost or destroyed then you have immediate access to their services.
