Additional erase required on blank discs

[loucypher]

A couple of days ago I did put in an erased DVD-RW disc, and started to write an ISO image, but ImgBurn asked me to erase it (full erase, slow): I was a bit surprised, but I acknowledged, and everythign went ok.

Today I had to copy another ISO image to a brand new (still wrapped) DVD+RW disc, and then again it asked me to do a full erase before!

Now... is that so common to happen?

Maybe I didn't notice it for a long time because rarely using rewritable media?

New DVD+RW discs aren't usually preformatted and the drive will error out if you try to issue a 'write' command without having formatted it first.

 

I don't know what the problem was with the DVD-RW, the program would never ask to do a full erase on one of those. It's a quick erase (if the drive claims it isn't blank/empty) or nothing.

Do you know if you used that first disc for writing in another program?  I've noticed that some programs seem to apparently to do weird things in writing.  ImgBurn wants to fully erase them after they've been used.  I haven't had that happen in a while so I don't know what program it was that did that for me, but I have encountered it before.  It makes no sense, actually, that it should but I have had it happen.

I rarely use DVD-RW/+RW (had more experience with CD, but that's another matter), so I didn't remember about having to pre-format +RW.

Right now I'm rewriting the +RW, and it didn't ask for reformat this time, fine.

 

That said, sorry about the -RW: actually it's another +RW, my mistake. Then it could have happen I erased it long time ago, putting it back to non-formatted state, here's why it had to be formatted again.

Well... all explained by my mistake above

 

Thanks to you both, now I know a few more things about DVDs

Great job with ImgBurn, and I love the music theme on finished operations
