I am having trouble with the backup utility of Vista.

I am successful in launching the application and initiation of it. It analyzes and informs me of the need 22 cds or 3 dvds. I go to write to dual layer dvd and once I was able to get Vista to write and verify the first of the dvds. I didn't launch into writing the second dvd with system generated statements ranging from: a. no disc, b. corrupt or unusable disc, c. incompatible media.

Of late, I can't even get the first dvd to write. I finally did get an error code: 0x8004007 (I believe that is it, I don't have the actual code in front of me.)

Has anyone else encountered this problem? My device manager and subsequent analysis tells me the drivers for the dvd writer is uptodate.

Thank, Matthew
