Writing to Pana DVD-RAM

Writing to Pana DVD-RAM

[cacook]

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?

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 :)

Cheers,

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.

I am using UDF2. (UDF2.1 won't mount)  Would I be better off with UDF1.2, or FAT32?  How can I get details of the driver's capabilities?

Please decode that oops and send it along, see REPORTING-BUGS

To recap: running Panasonic LF-D101 DVDRAM drive on SCSI (AHA2740) and
getting segfaults.  On-disk format is UDF2.0, as 2.1 won't mount.

Mount, ls, umount, mount, ls, umount, etc - no problem.

Mount, cp <20Mfile>, umount, mount, ls, (20Mfile), umount, mount, ls, (20Mfile),
rpm -q 20Mfile, umount, etc - no problem.

Mount, rm <20Mfile>, Segmentation Fault, umount, (device busy), umount, (device busy), etc.  Reboot without reset and bootup hangs at Running Linuxconf hooks.  Boot to Windows & try to access DVDRAM & it says "Not formatted, would you like to format?"  Power-cycle =only= the DVDRAM & then it works fine.  The Linux CD driver is messing up the controller in the drive.

Reset system & boots fine to Linux.  Mount, ls, (no files), umount, mount, ls, (no files), umount, etc.

Again copy file to, & it seems fine.
