Hi, I burned the 2 DVDs with everything, and then started to upgrade my SL-6.0 (with testing of the DVDs). When the upgrade of the first DVD was finished, I was asked for the second DVD. But the drive remained closed, and the first disk kept on spinning. Finding no decent way to insert the second disk, I eventually mechanically forced the drive to open (with a paperclip in the tiny door hole). The sound of the spinning disk was so disturbing, that I pulled the power plug. As my SL-6.0 was just a toy version (still using a a RHEL6 trial), nothing was lost, and with a re-check of the quality of the first DVD, I now did a new install. Now the drive door did open when the first DVD was finished, and I could finish the installation without problems. I will not use the 2 DVD upgrade anymore. Just wondering if other people also experienced this problem. (Apart from this, I am a happy SL user for many years.) Regards, Fons Laan.
