There is a problem. It is necessary to write down on API or AntiveAPI the information on DVD. Somebody sometime did something similar? Or even knows where to take the necessary information.

Thanks.

I'm not very familiar with this "problem" but you may looking for IMAPI Interfaces.

What exactly are you trying to accomplish? What kind of information would you like read from the DVD? Your first post was difficult to understand.

Excuse me in advance, my English is not so good. The information is necessary to me how to make read/write on DVD disks by using WinAPI. At somebody is though any information in this occasion?

you can read them same way you read any file on your disk, just with different drive letter.

i believe writing to DVDs is not supported in basic WinAPI

2vid: You not absolutely have understood me. And most likely I again was not absolutely clearly expressed. Me interests low-level read\write. I know, that writing to DVDs is not supported in basic WinAPI. But I hope, that there are any built in interfaces of work with standard drivers Windows which allow to do it from Ring3. And I also hope, that at someone is though any information.

I wrote once a program that could read cds/dvds. Just search fopr ISO9660 standard, and there are all structures of cds/dvds listed.

2 Reverend: Your program could read RAW data?

What do you mean by saying "RAW data"?

I post here my code + includes for reading cds/dvds

BUT, this code is from my old project which I left. The code contains "osscalls" - these are my attempt to make this library OS-independent, and so you'll have to change the code to make it work. Feel free to use it. If you have any questions, just ask me by e-mail or PM.

2Reverend: Under " RAW data " I had in view of reading sectors. Thanks for sources, I shall analyse it.

Reading disk sectors is like reading a file. Just use CreateFile on "\\.\D:" (D: is an example drive letter of course). This will return you a handle just like file. You can use it for ReadFile and read sectors, that's all

2Reverend: Thanks. But how to be with not structural data? I.e. in such a way it will be possible to read the data who have been written down on a disk not in standard ISO?

Every disk must have some kind of structure. If it was chaotic, the system wouldn't process it properly. It's just computer, it must have it written in a specific way, it cannot guess. The only problem may be to find that current structure specification. For ISO9660 it isn't hard, but there may be some other standard and its specification may not be available.

hi,

long time no see, im working hard now,
but im here,

i did a google on the subject, and i found some interesting results
you could access atapi devices via winapi, aspi drivers, or directly there are some functions in Ralph Brown's Interrupt List too.

that whould have helped me too before i had internet connection, i wanted to write a disc eraser software... because there wasn't any there is now.
