Data Loss Possible? Using Multi-Session

[21st Hermit]

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.

Yes, it's a risk. Probably a fairly small one, but if your system burps or something goes wrong with the burn before it writes the new TOC... you *could* lose everything. It may be recoverable, it may not. Depends what goes wrong. Not to mention, discs are cheap, HDs are cheaper.

I would store everything on the HD, and use 1 (or 2, if they are hugely important files) DVD-RW/DVD+RW (really doesn't matter which) to back up between burns. Then when you have enough for a full disc, burn 2 copies to DVD (preferably 2 different kinds of media).

I've never liked multisession. Hasn't worked well for me.
