Here's the scenario, I'm backing up some files into a DVD using an automated script. The script just takes the database entries as well as the files associated with them, and transfers them into the DVD. As I'm backing up, I'm pulling up the recording.log to make sure that it's backing up. It goes through and makes a file list of all the files on the directory, then procceeds with burning the files. When it gets to about 32-34 percent the program closes the DVD. To my knowledge the script doesn't have anything keeping the dvd from backing up only 32-34% of the data.

and you expect some1 to know whats wrong without telling us the distro, your your hardware, the software, or even posting the script, or error messages ?

Here is the recording.log

http://65.203.163.9/recording.log

System specs: AMD duron 1400, 256MB DDR 2100, Maxtor 120 GB HDD x2. Promise Fasttrak tx2000 RAID 0+1, NEC ND1200 DVD+RW, Shuttle barebone system.

Greetings p8ntcraze, and welcome to LQ. I attempted to view the log file that you linked to, but unfortunately the operation timed out. I'd like to suggest that it would be better if you could post the contents in a post here, that way folks will be able to see the exact messages, and also, assuming that log file may be deleted someday, posting it here will make it permanent, and will allow any future visitors to be able to see that information.

I'd also like to reiterate the points that qwijibow raised. The more information and the more context a post can provide, the easier it is for others to respond. As you know, you can optionally choose to specify your distro(s) on your profile, and similarly a lot of folks include their system specs as part of their sig line, which can save having to retype the same info in multiple posts. -- J.W.

i once had a similar prob. the dvd recorder stoped at ~ 20/30%. it turned out that the driver (i use kernel 2.6 and dev=ATA) didn't work with dma switched on. it worked well when setting hdparm -d0 /dev/hdd (=my dvd+rw).

Here's the script which makes the back up:

The recording log is waaay too big for me to post here, so i'll take out parts of it:

For some reason i can't connect via ssh to the remote system that's having this problem. I'm expecting another RAID card to come in, in a couple of days, once i make the identical system, I'll post up what I can about the system.

Here's more stuff:

anyone have an idea of what's messing up? what other info do u need?

I know this post is old. but I haven't been able to solve this problem. Please someone shed some light or lead me to a direction to solve this.

There is a problem with the 2.6 kernel and burning files that are larger than 2.2 gig. Take a look at this link: http://lists.debian.org/cdwrite/2004/06/msg00083.html. The only option that I have found so far is to burn using ide-scsi drivers; the same way the 2.4 kernels do.
