Data loss has special meanings depending on which you are and what you lose and the overall cost of replacing data.
Data Loss Problem
Data loss problem is one of the biggest problems faced by any computer user as data is very significant in today’s world where computer has penetrated in every type of set up. Data plays a very important part in any organization, business etc. When these crucial data stored in your computer system is somehow lost or deleted, then it can cause halt your work and can even cause serious harm to your business or work.
For companies, data loss represents a business risk and its negative effects on the operations can be significant.
The lost data may constitute important details about sales, manufacturing processes, future enterprises or financial reports. These even if lost for a limited time period affect the normal functioning of the company. Also, these details passed on to a competitor can result in major setback to the company.
Some service based organizations like banks and insurance companies have the personal details of their customers on record. They provide 24 hour online service to their customers. It is very crucial for their normal functioning and survival that these details are not lost or stolen.
Data loss leads to waste of time, money and effort as the normal functioning is stalled, employees sit idle while attempts are made to restore the data whether from a backup or data recovery techniques. Further trouble can be expected if the attempts fail to recover full or any part of data.
When you discover that you have suffered some data loss, the first decision is always if data recovery is possible. The subsequent action that needs to be taken depends on the answer to this, whether it is worth attempting data recovery or whether to find a way of managing the data loss
Data Recovery
If you have lost your computer data and don’t have any backup of that lost data; then, in this condition you can get back your lost data by using a third-party data recovery software tool to recover your lost data.
This can be a very difficult choice, especially if you are unsure what caused the data loss. A technician may already have attempted data recovery and the effects of some remedies, Microsoft’s “Checkdisk” for instance, are quite random.
The company you choose should also be capable of recovering data from many different storage media devices and file systems.
Data Recovery Tools
For efficient data recovery, you must use a high-performing and result-oriented software tool for recovering your lost data. Recover Data is a company that provides highly reliable data recovery tools.
Finally your chosen recovery company must be proficient in recovering data from a range of storage devices and be familiar with all major manufacturers.

Fix Damaged Images AFTER Data Recovery Has Been Performed?
I used a data recovery program to recover lost images from my digital camera. Unfortunately some of them came out grey. Meaning, when I look at the picture as a thumbnail, I can see the entire picture, but when I open the image, a large portion of it completely greyed out. Any idea of how I can fix these images? I’ve tried recovering them twice and both times the same images came out damaged.
The photos are damaged. The embedded thumbnails appear fine because they were pre-generated. Think about it like a lock and key: if one tooth of a key is missing, it’ll still fit but it won’t unlock the door. Recovery may be possible but only if you know what you’re doing.
Here’s how one person capable of preforming these recoveries describes the condition:
” – Grey Areas in your Image
In various forums on the internet, people have incorrectly stated that photos are unrecoverable if they contain gray areas. This is not usually true. Some JPEG decoders are very picky with how they recover from errors and simply report Drawing Failed (in Windows Picture and Fax Viewer), while others might draw a middle-gray region or just display a “Red X”. In some cases the gray area is in fact completely damaged (overwritten by unrelated data), but this is not always the case.
– Why do JPEGs get damaged?
There are many sources of damage to photo files, but the most common reasons are:
– Photos were deleted or formatted & a “recovery” utility was used
– Memory card / hard drive error (logical or physical error)
– RAM failure
– File transfer / interface error (memory coherency issues, buffer over/underrun, etc.)
– What Happens when you Open / Decode a Corrupted JPEG?
Even a single byte changed in a JPEG file can cause an image to be unrecognizable (or not open at all). Why? Because of the way JPEG compression is designed, images are stored in tightly-packed streams of binary bits (not bytes). Each pixel can be represented by as few as 2 bits to as many as 26 bits (dictated by the variable-length Huffman Coding scheme). To make matters worse, in an effort to keep the compression as efficient as possible, there is virtually nothing to indicate where you are in the stream of bits (unless Restart Markers are used). Therefore, as soon as a single bit is encountered wrong, the millions of bits that follow will be decoded incorrectly as well. The manner in which DC and AC coefficients are arranged in MCUs means that this corruption often shows up in shearing, wild color shifts and many other visual phenomena.”

It appears from the examples and comments that he or she is fully capable of preforming JPEG recovery when such operation is possible. Unfortunately, the author no longer accepts recovery requests.
There are similar JPEG recovery services available but your photos should be worth the cost. Here’s one example (I don’t know the reputation of the company so I can’t recommend it):

The company above seems to recover a small number of JPEG submissions for free for their own analysis and your benefit.
There are a number of recovery tools available too, but unless those pictures are very important they aren’t worth the money; you don’t know for sure if the files are recoverable, but mostly because you’ll only have the programmers word that it even works.
