The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

They do not  waer out, but like pictures, the data slowly fades away .
This is dependent on the type of media you record on.

All sorts of claims have been made, but I would not expect more than 10 years unless you store the media properly.


I hope this helps !

CD and DVD media will last a very long time.  Some manufacturers will claim up to 200 years.  Obviously this will depend greatly on the conditions where the media is stored, the quality of media, and the quality of the recording.  I have CD-R's that are 12 years old now, and are in just a good of condition as the day they were written, however they have been stored in jewel cases in a locked fire safe.  If you are considering this media for archival reasons I believe it will suit you well.  The largest concern I would have is the availability of a player at the time of retrieval.  I think the media will outlast the technology, given good storage conditions.  Remember the media is sensitive to UV (keep it out of the light).  There is a great write-up on this by the Optical Storage Technology Association at http://www.osta.org/technology/cdqa13.htm
