View Full Version : ? on backing up purchases onto DVD

May 24, 2009, 04:59 AM
Ok so I'm home from the desert & free from the sub-dial up internet speed over there, & have been buying songs of of iTunes like there's no tomorrow (actually, I only have 28 more tomorrows before I head back).

I got the pop up windo asking me do I want to back up purchases, so I say yes, insert an archival quality DVD , & back up, no problem, I think.

About 2 hours & 4 more album purchases, I get asked again to back up, so I reinsert the same dvd, & I get the message "insert blank DVD" .

I chose only to back up what has changed, & the info at the bottom of the screen when I click "Purchases" says I've only downloaded 3.63 GB, so I know the dvd is not full.

Did I miss a step, like having to format the DVD or something? I should be able to continue to use the same dvd until its full, right?

I don't think iTunes burns multi-session discs that allow you to keep adding on repeatedly. It will, however, split a backup up between multiple discs if necessary. Unless you have a DVD-RW or a CD-RW, you generally cannot burn multisession discs in iTunes. Read here for more info: Multisession discs not available in all applications (http://support.apple.com/kb/TA27735), Recording on a optical disc more than once (http://docs.info.apple.com/article.html?path=DiskUtility/10.5/en/duh1749.html).
