Vanishing DVD data - what to do?

[nzo]

I use a Ricoh MP5240A DVD+RW/+R burner and Ricoh DVD-R media. I generally write data to DVDs in several sessions. Several times I have burned an additional session (3 of 3) and on checking after the burn, the data was there. I also cataloged the DVD successfully with my media librarian and all the files, including those from the most recent burn, were there.

A week or so later, the files burned in the last session have vanished! This has happened with several DVDs.

I bought some Taiyo Yuden DVDs as they come highly recommended, but my Ricoh burner stalls when these are inserted.

Got me beat but I have to solve this issue - it's unsettling.

Appreciation and thanks for your help.

put these discs into another drive or use dvd decrypter or isobuster to extract the contents.

DVD was not made for multisession.
Try another drive.

Thanks to both of you.

I'm a little confused about: if DVD media is not made for multisession, how will trying a different drive make a difference to the problem of data loss?

I'm assuming from what you say that if I burn a DVD's worth of files to a DVD in one session, that will be ok?

I mean not all drives see mulitsession. Stop doing that.

Yes, single session.
