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.

Getting HDD geometry information../ writing to a sector in C

Asked by aktush in Miscellaneous Programming

[Ok I will be breef, I have not posted this article in C - Languages because it might not be possible to use pure C for this task, I have not placed it in ASM topics for the same reason.]

I need to write a customized software to override each sector on the hdd that uses 13h interrupt (aka IDE drives).

My question is:

1) How do I detect the drive geometry to calculate how many sectors and blocks there are to feed it to main loop that actually does erasure (writes to each sector).

2) Is it possible [and what functions] to use C to write to sector or do I have to resort to int 13h and use software interrupts for that matter. [This question would be then asked in ASM forum].

3) I am trying to make this software UNIX compatible what kinds of problems can I run into.

P.S

I know that Linux uses int80 does BSD or other UNIcies use the same? int80?

Thank you all for reading / answering.!
