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 isnt 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 computers 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 computers 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.

Whatever the cause, there is no reason to panic. The computer may no longer be able to find your pictures, but its unusual for a fault to completely wipe them from the storage card or disk. With the aid of some inexpensive data recovery software, youre 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 arent. 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.

1. Determine Whats Wrong:

- your computer will not start at all
- blue screen of death
- your computer boots up, but files are missing or are corrupted
- your computer opens up but you cannot seem to find some of your other drives

2. Weird Sounds

Before doing anything, try to hear if there are any sounds coming from your hard drive like a weird scratching, scraping or ticking. If you do hear something like it, then it is enough to conclude that your hardware may be physically damaged. The only possibility for you is to take your computer to a data recovery service where experts might be able to get your data off for you. Of course, this would entail a lot of time and money, so you may want to weigh the value of the data you lost before going a step further.

3. Do-It-Yourself Data Recovery Tips:

- Acquire and download software to help you out
- Not all software is free
- Attach your hard drive to another computer if your computer has only a single drive. This is to provide enough space to store all your data
- If your computer has a rollback safety feature, try and roll back to a previous saved state to restore damage

4. Possible Causes Of Damage:

- Lightning strike
- Virus
- Hard drive failure
- Accidental deletion of data
- Water/fire damage
- Improper software installation overwriting important data

5. Be Prepared – Make Backups

Having back-ups is the only solution to your data loss problems. They come in various forms:

- Virus protection software
- Personal firewall
- CD backup
- DVD backup
- RAID hard drive

6. Back-Up Tips

- Try investing in backup software of good quality and performance. Products that leave you secured from data loss disaster or further computer file crashes are always a good investment.
- Double check the restore capability. The software should have features that guarantee that while the product is performing your back up it checks all the data down to the level of bits and bytes.
- Double check the capability of your back up medium. Invest on the best back up software you can get and at the same time, for the purposes of prevention, start manually and diligently backing up your data regularly.
- Do an inspection of your hard drives from time to time. Always be on guard of viruses and spywares that can possibly crash your hardware. Defrag your computer regularly to correct errors and check bad sectors as soon as they are detected.
- Be sure you conduct a proper documentation of what transpired during the data loss disaster, what you have observed, as it progresses and the things you attempted doing to give your files the first aid. This will help the data recovery expert to track the problem and recommend the best solution for your problem.

Important Causes of Data Loss
What you hoped will not occur, perhaps because of no reason, could always hit you hardest unless you are safeguarded against them. Computer running slowly could be because of spyware scrupulously installed could be working behind screens to destroy or transmit data to their masters eventually causing hard disk to crash. Others like electric storms, power surges, mechanical failures, fires & floods and user errors (sometimes in disregard of warnings) could affect your computer without any or sufficient warning.

You could also loose data because of sudden but unintended deleting of files or programs. Accidental disk format, virus attack, partition loss are some more causes for data loss.

Data Protection
Data protection is the best policy than ruing over the loss. You can make use of trusted data backup software which automatically backup your data regularly, if you can’t do it yourself manually. Keeping backup of backups will safeguard you against the worst eventualities, too. Turn off your computer immediately as you hear strange noises like creaking run of hard disk. It is also wise to unplug power cords, modem and telephone cables when you are going out of home or office for a long time.

Data Recovery
The first thing you need to understand when dealing with data recovery is not loosing cool. Never act in haste and don’t attempt data recovery yourself unless you are an old hat at that. Call for professional help from your area and who you know.

Data recovery software does a neat job in most of the cases. There are quite a few reliable softwares available, no matter what platform your computer operates on. Data recovery softwares are available for Mac, Windows, Linux, and so on. Don’t attempt to use the software yourself out of gut feeling. If you must, check for user friendly personal packages.

An average company in US alone spends anywhere between $100,000 and $1 million in total for desktop-oriented disasters. This should more than emphasize the need for data safety and disk recovery.
