Cdrecord closed the disk without been told so?

Kernel 2.6.21.5, Slackware 12.0
Cdrecord 2.01

Hi:
I burned a blank DVD-R in the following way:

Code:

cdrecord -multi -sao -vv speed=2 driveropts=burnfree \

dev=1001,0,0 -data opera.iso

Now I've done 'cdrecord -media-info' on the same disk and I find:

Code:

disk status: complete

Of course, then, when I do 'cdrecord -msinfo' I get

Code:

cdrecord: Cannot read first writable address

In this way, I'm unable to write a second session. So, two questions:
(a) Does the message "disk status: complete" mean the disk is closed?
(b) In the affirmative case, what made cdrecord close the disk? Any hint will be welcome.

The man page for cdrecord (man cdrecord) shows that -sao means "session at once". I think that that automatically closes the disk. According to the man page, you might want to investigate the -multi argument, which creates a multi-session disk.

edit:
Also, the -tao argument seems important. From the man page:

Code:

      -tao  Set TAO (Track At Once) writing mode.  This is the default write

              mode  in  previous  cdrecord  versions.  With most drives, this

              write mode is required for multi-session recording.
