I've repeated this problem on three Compaq Evo 1.5GHz P4 machines. They have an Intel 82845 845 (Brookdale) chipsets with a Compaq CRD-8484B CD/DVD-ROM drive. Incidentally they make great test machines and are going really cheap on the second-hand market. Apart from this CD-ROM issue they have no problems with any version of Fedora or RHEL that I've tried. > I can't answer that question, but I can tell you that the -pad 800 solved > this same problem for the exceedingly generic ATAPI CD-ROM drive on my > Opteron box.

The number required is probably a lot smaller than 800, I will do more tests next time I burn CDs. But OTOH 800 sectors is 1.6M and there's enough space to spare. For reference I had discovered in that past that 50 spare sectors was the minimum to guarantee that no CD-ROM drives in my test network would fail the media verification (disks with less than 50 spare sectors failed verification and would sometimes fail on an install), so I chose 80 sectors to be on the safe side. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
