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!

How to get hard disk sector size in Linux?

Asked by Foma in Linux Programming

Tags: , , , ,

Hello!

I would like to write to disk in atomic way to support transactions. To achive this, I have to write to disk in portions equal to the size of disk sector size. The problem is that it is srangely difficult to obtain the disk sector size in Linux. In Windows I use GetDiskFreeSpace call which returns me "bytes per sector" value. As I understand, for modern hard drivers (ATA and may be SCSI, I'm not sure) disk sector size is equal to 512bytes... But anyway, I'd like to be sure and ask Linux/device/controller/whatevery-you-want, but I don't know how to do it

Thanks for attention to my question,
