Making an ext2 filesystem on a DVD+RW

[Jack Dodds <brmdamon@aci.on.ca>]

I am using Sarge with the 2.6.17 kernel from backports.org.

According to tidbits I have read on the Internet, DVD+RW
support was added to the kernel in 2.6.10, and I should be
able to make an file system on a DVD+RW with mke2fs.

However, it doesn't work:

mke2fs /dev/hdd
mke2fs 1.37 (21-Mar-2005)
/dev/hdd: Invalid argument passed to ext2 library while
setting up superblock

I also installed udftools and the pktcdvd module:

modprobe pktcdvd
pktsetup /dev/pktcdvd0 /dev/hdd
ioctl: Inappropriate ioctl for device

Can anyone advise me on this?
