One solution is to reboot and choose to skip the media test, then the install goes along as expected. Another is to eject and re-insert the DVD\/CD media. \u00a0This problem exists in at least CentOS 5.5 and 6.0 x86_64, and probably others and RHEL (<a title=\"Red Hat Enterprise Linux (RHEL)\" href=\"http:\/\/www.redwireservices.com\/wp-content\/uploads\/2011\/07\/rhel\" target=\"_blank\">Red Hat Enterprise Linux<\/a>) as well.<\/p>\n<p>I encountered the error installing under VirtualBox, where it seems the DVD may be &#8220;virtually ejected&#8221; after the test, but is not clear the DVD is ejected under VirtualBox. It appears a\u00a0bug is logged as fixed in Fedora 11, so a future update should improve this.<\/p>\n<p>I hope this saves you some time and frustration&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today I began my first installation of CentOS 6.0 and since this is the first time I&#8217;ve used this downloaded image, it seemed logical to test the media when asked, so I did.
