This happened to me last night as well. Exact same problem, the machine would not let it go. I think the install is not un-mounting the first DVD when it asks for the second one, this prevents it from opening. Luckily, I was using a USB dvd drive and just pulled the power to force an unmount. -Jordan _____ From: [log in to unmask] [mailto:[log in to unmask]] On Behalf Of Fons Laan Sent: Monday, August 01, 2011 10:03 AM To: [log in to unmask] Subject: SL-6.1 two DVD upgrade problem 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.
