I had the same problems with media checks on FC3 disk 2 and 3. I found that the disks I wrote on /dev/hdd would not verify when booted on /dev/hdc (a read-only CD drive). However, when I shut off /dev/hdc in BIOS and booted from /dev/hdd, I got good checks. The moral here: disks may read better when you use the same drive they were created on. I guess the padding will be compatible, etc. Also, I recorded the disks at 4X (slow), but I'm not sure that was necessary. Why was FC3 released when its ISO's couldn't reliably be burned & read? That seems pretty basic for a distro. The problem may be that an md5sum on an ISO is somewhat too strict. I believe it can fail sometimes even if all the files in the filesystem are OK. -Martin
