I have a CDR that had a session opened with Adeptec Direct CD Wizard. After files some .xls files were written to the CD. The session was closed. Later on, a new session was opened on the same cd to add some files. Upon closing the last session, theoriginal .xls files no longer show up on the CD. It seem that the allocation table was re-written without the original contents. I have done this many times in the past, and never had a problem. I need a utility that can read the entire contents of the CD. I tried the Scandisk that Adeptec has with their softwar, but it does not do a through scan. Any suggestions?

What happens with Easy CD Creator and multi-session CD-Rs, is the software imports the setup for the previous session(s).
If the files from the older sessions are not in their original locations, or have changed, they will be deleted from the CD.
The only way to aviod this;
1. Do not use multi-session CDs as data backups.
2. Do not delete files off of the PC when saving files to a multi-session CD.

Here is a link to a site that may have utilities that will work for you to recover thefiles.

I always maintain 3 copys of ALL critical files.
When I back them up to CD, I create 3 closed CD copies of the files.

At the $0.10 to $0.15 for bulk blank CDs, why risk loosing critical data on amulti-session CD?

I follow what you are saying, but the File Allocation Table should have been modified on the second session to include the orignal files. It has always worked in the past.
