Hi all, noob here...I burned several .ISO files to a DVD-R while using ImgBurn for the first time. The total was 500 MB, and I wanted to burn more files after that first session and it won't let me. Does that mean the disc can no longer be burned? Other programs show the disc as unwritable, despite that on visual inspection, only a small portion of the writable surface is used. After checking, I know now that ImgBurn only does a single session--should have checked beforehand.
Anyhow, could I erase the existing data (or ToC) using some other program, and use the remaining 4GB? Interesting that with ImgBurn after one session the disc appears 'closed', given that other burn programs I have worked with (Roxio, NTI, Nero etc.) allow multi-session burns.
Thanks in advance for any info.
