Can't close Sonic DLA formatted CD

[Shavit]

I have several CDs which were written on IBM T60 notebook, using Sonic DLA, but were not finalized, and I can't read some data on some systems.

I tried to use ImgBurn to close the disks, using Tools - Drive - Close, but there was no sign that anything was done

 

Earlier today, using V2.4.1.0, I had saved images to disc (with other errors).

Now, after using Tools - Drive - Close, and upgrading to v2.4.2.0 I can no longer save image to disc.

 

Q1. What is the right procedure to close a CD?

Q2. What is the right procedure to prepare a new CD, with all the data on it available on all PCs?

 

Disc data, and program log is provided herein

It seems to me that your drive just can't read the disc... unless you can find a drive that'll read it, you're probably out of luck.
