Understanding Data Loss


Computer users and many experts often consider lost data permanently destroyed, with no hope of recovery. And because much of the information about data loss is complex, inconsistent or inaccurate, it’s not surprising that data loss and data recovery are some of the most confusing and misunderstood concepts.

At Kroll Ontrack, we take the mystery and much of the expense associated with lost data out of the equation. Our data recovery engineers have studied data loss and have been performing successful recoveries for 20 years.

Their findings indicate that in most cases, data is recoverable no matter what the circumstance. So, never assume your valuable data can’t be recovered. Always check with a qualified data recovery expert before determining what to do when data loss has occurred.

Causes of Data Loss
The chart below clearly represents the complexities and differing perceptions of data loss between what customers believe caused their loss and the impact of the loss versus what our engineers actually discover once they evaluate each situation. These findings reinforce the complexities of lost data.

Software Corruption or Program Problem

Why does data loss happen?

Data loss happens for a number of reasons, and at virtually anytime and anywhere. No one factor can ever truly be overcome, which makes data loss a reality. It is not a matter of if, but rather a matter of when data loss will occur. As a result, businesses and home users alike cannot rely on hope as their strategy. Data may be recoverable with Remote Data Recovery™ service (recovery through modem or Internet connection) or even with data recovery software.


Costs of Data Loss
With no data and no access to your system, lost data is a financial disaster. Our data recovery specialists determine the best data recovery solution to get you back up and running as quickly as possible. The chart below outlines the costs associated with computer downtime and lost data for businesses.

    By mistake I sent many e-mail that contained pictures of my son to the trash. Then on October 19, 2012, unaware of my mistake I deleted all from the trash. Is it possible for me to recover all these e-mails and data?

    For a HDD with many bad sectors, is full recovery of data still possible? And does a prevalence of bad sectors indicate that data is lost forever? Or can Kroll Ontrack Labs recover this data?

    I just did a system recovery a few minutes ago, because I couldn’t start y computer for some reason. Now all my data is gone. Is it possible to restore pretty much everything? I had not only movies and pictures on it, but games and work data.

    It’s great that there are ways to recover most data — I am so careful to back up everything on a regular basis — I couldn’t imagine if I lost everything! Great post! Thanks 🙂
