[Help] Trace the content to CD + R in linux. After the content is finished, the new content cannot be seen. -- Linux general technology-Linux technology and application information. For details, refer to the following section. I have a DVD + R file used to save the photo files. In the past, the content was regularly appended to the CD under windows, which is normal for use. Some time ago, the windows system failed and the re-installation was always unsuccessful, so it was completely changed to the door of fedora12. You can burn other unburned files on the hard disk to this DVD + R, and use the default burning program on the fedora12 desktop.

You can see the content burned in windows before burning, but after burning ...... You can only see the burned content in linux ...... I can't see the previous 3 GB of content, and I am familiar with viewing the CD. The file size is also the size of a new image ......

Depressed, how can I restore all the original content? Don't get a cup ......

Thank you!
