Hi,
I formatted a dvd-ram with udf:
mkudffs --media-type=dvdram /dev/scd0
Than after mounting the dvd-ram I can copy files to it and a diff shows
that the copied files are okay. To ensure that the files have really
been written I switched the writer off and on and mounted and ejected
another dvd between cp and diff, and there were no differences.
But if I try to recursively copy directories to the udf-formatted
dvd-ram:
cp -r /some/dir /media/cdrecord
than after a few seconds the system freezes totally - only a power
off/on to reboot is possible.
The same occurs if I use Nautilus for the copying.
However if I formatted the dvd-ram with ext2 filesystem, all went fine,
no problems.
I run Ubuntu 5.10 with kernel 2.6.12-10-amd64-generic on a Dell OPTIPLEX
GX620 (Intel P4 620, 1G RAM), the dvd-writer is a NEC ND-4550A (Firmware
1.07), connected via USB2 with a Cypress Semiconductor Corp. USB-2.0 IDE
Adapter.
Strange: why do you run a amd64 kernel on a Pentium 4?
I would check this out before investigating further.
Also check the output of syslog.
Why don't you post to Ubuntu?
