AMD64 running 6.0
Drive is:
acd0: DVDR <HL-DT-ST DVDRAM GSA-4160B/A301> at ata0-master UDMA66
Media is CD-RW
Burned a 6.2 disk using:
burncd data 6.2-RELEASE-amd64-disc1.iso fixate
as suggested in
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-cds.html
Seemed to go okay. Disk boots, but I cannot mount it:
fstab entry:
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
Yields:
g_vfs_done():acd0[READ(offset=32768, length=2048)]error = 5
Tried it with and without "fixate", neither will mount.
Other iso disks (probably burned using NetBSD) mount fine.
UFS DVD+RW disks burned under FreeBSD using growisofs mount fine.
Given the error message, I assume that the block/sector at 32768 isn't
getting written.
