can not write files larger then 2G to system....

lleb · 01-28-2007, 08:18 PM

how do i get around this. running Debian etch

Code:

uname -a
Linux debian64 2.6.18-3-486 #1 Mon Dec 4 15:59:52 UTC 2006 i686 GNU/Linux

everything is etc3 (think that is the proper file system name) or something 3, the standard file format i have used since i started messing with linux.

system specs if you need them:

AMD 3800+ X2
2G PC3200 ram
sATA 7200rpm 250G
Asus A8N-SLI Premium MB
DVDR/W dual layer internal
DVDR/W dual layer external USB2.0
floppy

yes the system is apt-get update its a rather new rig so nothing should be messed up with it

i am trying to use vobcopy to make a backup of my Pirates of the Carabian DVD for the wife. could not get DVDShrink or AnyDVD to make successful backups under XP so i tried k3b, and still no luv.

now with vobcopy i get the following error:

Code:

sudo vobcopy -l

[Error] It's possible that you try to write files
[Error] greater than 2GB to filesystem which

so it refuses to let me write larger then 2G file... what gives?

Execute this command while in the same directory as you tried to execute vobcopy and post the output:

Code:

df -T .

I encountered a 2GiB limit problem about a year ago while trying to burn backups onto a DVD. Something, somewhere is not built to cope with large files. This is the 32-bit file pointer problem. *sigh*. The problem can come from several points.

What happens if you don't use the -l option to vobcopy?

lleb · 01-28-2007, 09:15 PM

same error

matthewg42 · 01-28-2007, 10:15 PM

What output do you have for this command:

Code:

strings `which vobcopy` |grep seek

lleb · 01-28-2007, 10:55 PM

Code:

ray@debian64:~$ strings `which vobcopy` |grep seek
lseek64
[Error] Couldn't seek into the drive
ray@debian64:~$ sudo strings `which vobcopy` |grep seek

looks like vobcopy is compiled OK.

Try to create a file which is more than 2GiB using another tool:

Code:

dd if=/dev/zero of=mytestfile bs=1024 count=$((1024 * 1024 * 5))

(this will try to create a 5 GiB file)

Paste any errors here.

lleb · 01-28-2007, 11:56 PM

Code:

ray@debian64:~$ dd if=/dev/zero of=mytestfile bs=1024 count=$((1024 * 1024 * 5))
5242880+0 records in
5242880+0 records out
5368709120 bytes (5.4 GB) copied, 210.356 seconds, 25.5 MB/s

so it seems that there is zero problem with my system writting files that size, and vobcopy just not working properly.

any other clues suggestions on how to make a playable backup of my DVD?

ok just some side info that may or may not mean anything here.

i just installed DeCSS on my windows partition to see if the CD was encrypted or not after checking the 7 main VOB files, none of them reported back as being encrypted.

also DVDRIP can not rip the main movie out to an AVI file, nor can it copy the VOB files out to the hard drive.

how in the world can i make a backup copy of my bloody DVD. the wife has already burned through 1 DVD (Pirates of the Caribbean 1 and 2) and i just got it for her for Christmas.

yeah she watches it that much. thus the massive desire to back it up so i am not replacing this thing every few months.
