我想从 openSuSE 12.2 升级到 12.3。
因此我刻录了 openSuSE 12.3 发行版 (32 位) 的 ISO 文件。准确地说，我刻录了两次，因为我想知道这个过程会产生一个 4.2 G 的文件，这是错的 - 这是正确的吗？
好吧，由于第一次下载的文件大小也是 4.2 G，所以我刚刚下载了另一个文件，也是 4.2 G。这里出了什么问题！？
附上 K3B 刻录协议 - 我取了页眉和页脚。
你说呢——这一切都正确吗？
我可以继续升级吗？我想不行。我必须告诉笔记本电脑必须从 DVD 启动。但是 - 我该怎么做！？

不要生气下载页面标明“4.7GB DVD”——这仅指介质，即单面 DVD。图像文件可能更小。
只需使用提供的 MD5 校验和 (http://download.opensuse.org/distribution/12.3/iso/openSUSE-12.3-DVD-i586.iso.md5）来验证您的下载是否正确。在下载 ISO 映像的目录中使用以下命令行：
md5sum -c openSUSE-12.3-DVD-i586.iso.md5
刻录过程本身看起来很好——每个字节都已写入：
Track 01: Total bytes read/written: 4534042624/4534042624 (2213888 sectors).
k3b如果您想随后检查刻录的数据，请使用“验证”选项。
