I'd like to see a verify function built into the burning engine so that after a CD is burned, the filesystem contents are checked against the source files for read errors. This helps me avoid coasters (of which there can be several in each spindle of discs I buy). My bootable CDs don't work well unless I am able to verify that they're not coasters.
What I've done for now is make an .iso file out of the source files, created checksums from the ISO, burned a CD, and then checked the CD checksums against the ISO checksums. This is a lot of extra steps and it would be great to see a simple checkmark in the burn dialog for verification (like Nero has).
