Then as what filesystem are you trying to format?
CDs are often used with the ISO9660 filesystem. That's a read-only
filesystem, that isn't formatted but burned directly to the media.
UDF is another filesystem, that can be used with CDs and supports
read-write. read-write directly with CDs (CD-RW and DVD+/-RW), though,
only via packet writting.
According to the documentation (in the kernel,
Documentation/cdrom/packet-writing.txt), the way to use packet-writing
and udf is:
1. low-level format the media:
a) cd-rw: cdrwtool -d /dev/hdc -q
b) dvd-/+rw: dvd+rw-format /dev/hdc
if dvd+rw, then:
2) mkudffs /dev/hdc # format the disc
3) mount /dev/hdc /cdrom -t udf -o rw,noatime # mount the disc
if cd-rw or dvd-rw:
2) pktsetup dev_name /dev/hdc # set packet-writing and init the filesystem
3) mount /dev/pktcdvd/dev_name /cdrom -t udf -o rw,noatime # mount the
disc
These utilities are available in the package udftools:
yum install udftools
Hope this helps.
