I have a DVD burner and just picked up some blank DVDs.
I havn’t burned anything since… oh… data files on blank CDs a couple years ago.
They have a little RW symbol there on the disc away from the DVD+R logo.
I tried to delete a file I burned just to see if it’d work… and the 2 gig file was deleted. “Oh cool…” I think “They’ve gotten rid of the line between R and RW discs as which one is standard”.
Then I try to add several files (nearly filling the disc) and it won’t let me, says there’s not enough space. Hmm… Why?
A blank disc put in works fine, burns all the files.
Do I have to format the disc again?
Was I just dreaming that the RW thing actually works?
These arn’t just RW discs, I don’t think, I bought them because they seemed the most basic (Just plain old R+ dvds)… not that I know what +R or -R mean…
You seem to be confused as to the differences. RW discs can be erased and rewritten. R discs cannot. When you “deleted” the file you only marked it as removed in the disc’s header. The data is still permanently on the disc. +/- refers to compatibility with drives. DVD+ discs must be used in a DVD+ writer, and likewise for DVD- discs. Many drives are +/- compatible nowadays, though. There are also compatibility implications for standalone players, but modern players can handle both DVD+ and DVD- discs.
I just looked at some of my DVD+R discs and noticed the same thing. The “RW” symbol is the logo of the DVD+RW Alliance, which developed the specs for the DVD+R and DVD+RW formats. Supposedly they have a web site, but I was unable to get it to load without timing out.
In short, you do NOT have DVD+RW discs. If they were, they would be labeled as such.
Why would it let me remove the documents from the index? I lost a bunch of information messing around like that… I mean, if its on the disc for good and its not at all RW, why let the directory be deletable in part?
Until the disc is finalized, you can delete items from the directory (but I don’t think it actually removes the data from the disc – I may be wrong). Before you can read the disc on another machine, you have to finalize it, which is one of the steps in your burning software. Usually this is done by default at the end of the write session.
