I've just purchased Toast 12 as part of my archiving solution.
I have been trying to create an archive of 30 spanned DVD discs. On the third disc burn of the series, I get a verification error. I've inserted new disks as requested by the interface only to produce the same error 3 times, giving me now 3 extra discs with verification errors and 2 discs with complete verification. I have checked these discs and they all seem ok but I cannot move past this error without possibly resetting the whole process. (which I have now done). If I attempt to to burn disk again this may well happen again. Leaving me with more wasted archive discs.
I'm running up to date OSX (Yosemite) and using the latest LG DVD burner. The files I'm burning are raw Nikon files, tiffs and jpg (some very large ones greater than 1GB) .
Can someone please advise on the way forward?
