with feurio! you can test your cdr's (and your writer) for overburning capacity.

Burn large files without overburn. 

Am I the only one that HATES Nero with a purple passion?? But I digress... I use Padus DiskJuggler for my movie burning, and always goto the advanced options, change to "Mode 1 CD-ROM" and check the box to close disk. I don't have to check the overburn option at all for files around 730mb (too lazy to pull out all my old disks and check), and have done 760 on a regular 80min cd with overburn. The combination of these 2 options makes a much smaller filesystem on the cd and allows more usable data with no loss of EC functions that I'm aware of. Feel free to correct me on that if I'm wrong though. :) I am not nice to my cd's (well, my roommates aren't at least) and haven't had one go bad on me yet. Well, the one I ran over with my chair don't count. No EC scheme will play a disk that's broke in half. hehe

@ borg Sorry, but 80min CD-Rs capable of storing more than 720MB are very very rare. 730MB *may be* possible on some very rare 80min CD-Rs, but 760MB is definitely out of the range! And Choosing Mode1 or Mode2 for data CDs don't have influence on the capacity or EC. And overburning is done for *every* CD which have to store more than 703MB. And overburning requires that the disc is closed so you can't do anything here.

I think there are many ppl just looking the file size in Explorer which shows the filesize in KB's and when they see 718 000 KB they think of 718MB when it infact is only ~701MB. btw. im not saying that anybody here does that...

Overburning capacity depends on the media and the writer (but mostly on the media). So, choosing another writing program will not make cdrs more or less overburnable. I have tested many CDR's for overburning capacity in Feurio! (it features an overburn test) and the most overburnable 80 min CDR I ever had was overburnable to 84 point something minutes for audio. That would make almost 30MB for Data, I guess. Most CDRs are only like 82-83 minutes, though. I'd also say 60MB is impossible!
