Is there any other way to identify a CD-R besides ATIP?I need to be able to check for a CD-R in a CD-ROM drive, that is not able to read the ATIP.Thanks!!
If the disc is ROM and not audio, you might be able to check for link blocks. This would probably only work if the CD-R was written in TAO mode. This might not work on all CD-ROM drives though. It's possible that some will block the reading of what 'might' be link blocks.
Hope this helps.RM
Do you know if there is any way to check that from a command line based application, like wodim, or cdrecord, or readcd?Thanks a lot!!
I'm not sure if those programs would do it or not. You would need to read the correct sectors (complete 2352 bytes) and then check the MODE byte of the header.
Hopefully someone else has knowledge of what those apps can do for you.
Do you know any way to do this with any command line tool?And if you do, can you give me detailed instructions on how to do it?I don't really understand the technical part of your idea But if you tell me how to do it, I'll be fine...Thanks a lot!!
Are there any other ways that would work to identify a CD-R in a CD-ROM drive? Please help!!Thanks a lot!!
Would it work to read the date the cd was burned, or the program it was burned with?And is there any way to read this from cdrecord or any other command line tool?Thanks a lot!!
Neither of those would help. It is common for publishers to burn a CD-R and send it off for replication. The complete contents will be put on the replicas. This includes dates, burning software, etc...
Can't you use device profiles, once the disc has been inserted?
Added: Posted too quickly ... if it's a CD-ROM device, it will clearly not have a CD-R profile.
Unless a CD-R is written in Disc At Once mode, it should have a Track Descriptor Block in each Pre Gap. Does anyone know if this information is carried over when a CD-ROM is created from a CD-R master?
