To Date, my only use of DVDs is to backup my RAW photo files. Frequently, a photo session will not yield 4GB of data and I'll use multi-session to fill a DVD.
Am I at risk of corrupting a disc by adding 2nd and 3rd sessions? Does it matter +R or -R, the NEC 3520 burns -R a bit faster, better?
What burning strategy I should follow?
Thanks.
