Burning Disk 1



Hi.  I recently downloaded Fedora Core 2 test3 for testing.  I checked
all of the files I downloaded with md5checksum and all came out ok.  The
problem I have is burning the software from disk 1.  Disks 2,3 and 4 all
burned successfully, and checksums for the disks are ok.  I burned disk1
onto a 650MB CDRW using cdrecord -v -v -v -v -speed=4 -dev=/dev/cdrom1
-blank=fast -overburn FC2-test3-i386-disc1.iso.  Checksum fails.  I've
used different CDRW disks, and 2 CDR (700MB) disks, with all
burns/checksums bad.  I can go back and burn 650MB of other data to the
CDRW disk without problems.  Is there something special that I have to
do to burn disk1?  I'm currently running FC1 updated with yum, and
Kernel 2.6.6-rc3-bk3.  I have also installed hotplug/udev (without
problems).  I understand that the disk1 iso might not fit on a 650MB
CDRW, but after 2 bad burns on CDR, I'm asking questions.  The error
message I get when the burn dies is:

cdrecord -prcap -dev=/dev/cdrom1 shows:
Maximum read  speed:  4234 kB/s (CD  24x, DVD  3x)
Maximum write speed:   706 kB/s (CD   4x, DVD  0x)
Buffer size in KB: 2048
(so I can write at 4x without problems).  The writer is (actually) an HP
CD-writer Plus.

Thanks,
Bob
