Writing to Pana DVD-RAM

Hello,

I am running RedHat Wolverine (beta) with kernel 2.4.2. I have a SCSI subsystem (AHA2740) with a Panasonic LF-D101 DVDRAM on it.

I read that the CDROM driver is built to recognize DVDRAMs and allow writes; well I can mount and read the UDF file system fine, but am not allowed writes. I have UDF2.0 on the disk, because it didn't recognize UDF2.1.

Also, when I make xconfig, it includes UDF support, but read-only. (Write-Experimental is grayed-out)

In fstab: /dev/scd1 is mounted to /mnt/dvdram udf default 0 0. (paraphrasing)

I need the DVDRAM for backups and file transfers. Is the problem the driver, the UDF filesystem, my setup, or what? --
C.

The best way out is always through.

Check that "Experimental " is enabled under "Code Maturity level options", if you can't find it try using "make menuconfig" instead of "make xconfig" Note that the UDF-write support option is listed as "Dangerous"... possibly making things difficult, but then again if you have a DVD-RAM, how bad can things be :)

DOH! You're right.

I can now write to it, but only get one chance. Copy a file to DVDRAM, read, print, etc, but when I try to rm or mv, segfault. Foreverafter the DVDRAM is 'busy'. Cannot umount. Must reboot then umount. Remount, get another write, but on subsequent write, segfault.
