I don't currently have Ghost 15 running so I don't recall the exact numbers but one of the advanced options is to split the "cold backup" image into several pieces using a choice of different sizes. One would think that the most obvious choice of size for DVD would be to choose the option 4589 (or something like that) but when I did so and then subsequently tried to burn that image to a 4.7 GB DVD, the burning software told me that I don't have enough room on the DVD. However, stepping down to the next size (something like 3689) seems like I am leaving too much "on the table" and in this case, it actually costs me another DVD to do this, whereas if I were able to select 4300, I could get away with two DVDs only.
Unfortunately, it doesn't appear as if I can specify the size myself - there is no option such as "Custom Size" in the list.
I don't understand why Norton did not offer a standard DVD size - is there any way to specify this - even via command line???
