more than 1000 pictures disappear from dvd+rw disk, help!

We strongly discourage use of so called packet writing software to use a DVD as kind of a gigantic floppy or smallish USB-stick. Those are unreliable, as you see. That's all that can be said about it, since you didn't tell what program you used to write to that DVD, nor anything about your OS (Windows XP, Vista, 7, 8?).

And a more general remark. If you have an original and you make a (backup) copy of it, you have 2 copies. If you delete the original, you've only got one copy and no backup. Then if something goes wrong, it's gone. That's why we strongly encourage members to make a backup, and preferably more than one, of everything they don't want to loose.
Some of our members learn that too late.

It could be the disk isn't 'closed' yet. In that case, it might help to close it now. If not, contact drivesavers.com and ask them if they can recover your pictures and how much it will cost. Most likely, much more expensive than a backup would have been.

it's a painful one. As Kees points out, too many people learn too late. It's a shame to see so many people having to learn this way, I just hope that I'll see the day when this becomes common knowledge. When you've gotten your system back like you want it, I urge you to get yourself an external hard drive and a good 3rd party backup program. You can set it up to do everything automagically at the time and frequency of your choice. 1 TB external hard drives are about $70 these days and a really good FREE backup program is the Easeus todo backup free which you can download from
http://www.todo-backup.com/products/home/free-backup-software.htm . That can save you a lot of time and frustration the next time something like this happens. Sooner or later it happens to all computers for one reason or another.
CNET has a lot of backup program reviews at
http://download.cnet.com/windows/backup-software/?tag=contentBody;sideBar .

Some of these are free (last time I checked there were over 300), some have free trials (over 1000), and some are purchase only (over 200).

Good luck.

I'm unsure how many times we've told folk to stop using that system. We also write "we only lose what we don't backup."

Given the dollar each of those discs can cost, if it was worth saving, where is the backup?

and see if it can see the photos on the CD-RW or your hard drive. There is a free download through CNet. I used the program to recovery photos from a memory card and got all but the 2 that were corrupted.

Thank you all for your answers...guess I won't be using dvds to save files anymore.

about 400 of the pictures using Piriform Recuva though. It was free too!
