I have a Sony DVD read/write drive in a computer that's running Ubuntu 9.04 desktop 64 bit. I primarily use it for VMware 2.0 server and build virtual servers, mostly Cisco Unified
Communications applications for my lab. Over the past months, Numerous discs will work the first time, that is, I'm able to build the virtual machine with it. But, the second or third time the disc won't read or the install will fail. And, on most of the apps, there is a media check before installation. The disc will pass the first time but fail thereafter. The discs all seem to involve media with a purple bottom. Could the disc player be corrupting these? If so, how do I stop it? When I create an ISO file and install that, the install will fail at the same place as the disc. What to do Next?
