Hi,
I am tring to get a large single file written/read to a DVD-+RW on a Linux 2.4 machine.

I am having a problem getting a single compressed (tar) file larger than 2.1 GB written to disc.

The drive is a Sony DRU-500A, and the firmware is 2.0c.

I am told the "large file size" is enabled on this machine.

I am using the latest demo available from GearPro.

Help!

What version and rc are you using? There is a known bug with files greater than 1GB in certain versions.

Hello,

I am using Gear Pro 5.00 on a Linux machine using Red Hat 2.4, and the firmware on the SONY drive is 2c.

What is "rc"?

Like I mentioned, I can burn a single tar file up to 2.4 GB on a DVD. After I erased the previous file, the next file I tested is 3.0GB and it does not appear to be written properly. I did not take it to another DVD drive to see if just was not reporting the 3 GB file was read incorrectly.


Thanks

I burned another DVD+RW this afternoon. I started with a 2.2Gb file.

It appeared to burn the file but ended up reporting that the file is only 6.5MB.

I'm going to take the disc to another machine to see if it just reports it wrong, or actually is a 6.5MB file.

Where do i find the "rc" number?

Is 5.0 the latest release for Linux?

Thanks

The rc number is the release candidate. It identifies the specific version or build of each copy of GEAR. You find it in the "About GEAR" dialog box that is found in the help menu of the GEAR GUI. You should see both a version number, followed by "rc xx", where xx is the rc number.

In the "Help" "About Gear" window, I see "GEAR PRO Unix 5.0, Jun 11, 2004", no "RC" number.

Copyright @1992 - 2003 GEAR Software

I did take the 2.2GB DVD to my PC and saw a 2.18 GB file on my Windows 2000 DVD reader. So it's something about reading the disc back?

I arranged a 60 day demo with Mr. Sam Plummer. So far I have spent about 1/2 of that trying to get it to work right. Help.

You can contact support@gearsoftware.com and we can give you the link to download GPL 5.01 beta.

I have had the beta downloaded and installed, but we are running into an error when I try to start the program.

Quote:
/usr/geargui/bin/geargui.1: relocation error: /usr/geargui/bin/geargui.1: undefined symbol: _ZN7QDialog8setModalEb



The system admin believes that error has something to do with building dialog boxes in java for the display. He installed the newest j2re for Linux and explicitly set the LD_Library_Path for the new java. He included paths to most of the standard system libraries in case somehow they were being ignored. No difference. He is guessing that there is a library missing or there is some X-Windows factor library missing that we need but don't know about yet.


Got any ideas?

Thanks
Darwin Cool

Darwin,

You should be able to use the CLI (command line interface) of GPL. I believe that there may be a bug with the libraries for GPL. It is being looked into. Instead of running geargui, try running gear from a console window.

:cry:

Well, I started the GearPro for Linux in command mode, but not sure how much good it does me. I have a DVD+RW disc loaded.

I think I may have gotten it to write a test file, but it just difficult to use this way.

I basically can get it to do the simple commands.

CHECKDRIVE:
Disc loading type is: tray.
Tray of the recorder is closed and unlocked.
Disc is loaded.
Background formatting progress percentage = -1

RECORDERINFO

Special read options:

Reading CD+G (96 bytes R-W subcode data): Yes.
Reading C2 errors for audio: Yes.
Scanning audio indexes: Yes.

Basically, I'd lie to ask for a specific sequence of commands to write a test file and read it back.

Can you provide such a sequence?

DISCINFO

Before I checked back, I had some success with the command line interface.

After your post, I think I saw what I was missing. I will post more on Tuesday.

Thanks Laughing

PostPosted: Thu Jan 06, 2005 10:24 pm    Post subject: I burned a 3.8 GB single file on a DVD+RW Reply with quote

Randy,


I was able to burn a 3.8 GB single (file) tar file to a DVD+RW.

I used the "batch format" as we are unable to use the GUI. I was NOT able to read the file I wrote on the Linux machine correctly after I had burned it. It reports the file size as 1.2 MB, and will not open correctly. If you look at the log file I created during the batch execution, ir reports the right size as it's burned.

If I take the burned disc to a PC runing Win 2k, it reads and reports the file normally.

Are there any Linux limitations reading large file sizes? I had no problem creating the tar file on the Linux machine in the first place.

I also was successful writing a 1.2 GB file to a DVD-R disc. This disc is able to be read correctly. My next test will be a 3.8 GB file on a DVD-R.


This is the batch file I used for the 3.8 GB file on a DVD+RW - Can you look it over for any "red flags"?.
----------------------------------
log dvdtest_batch.log
newvol dvdtest_batch 509
newtrk isoudf
copy /xxxx/adamsdg/DVD/3.2GB.tar
writecd

The resuults from the "dvdtest_batch.log file are below.

Darwin,

I see you made a ISOUDF project. That may be the problem. ISO has a limitation for file sizes up to 3.5 GB. UDF is what you would want to use to burn a file larger than 3 GB.

Why it worked on Windows? Windows was showing you the UDF part of the disc which burned correctly. Linux by default will mount the disc as ISO, giving you the wrong information. Try forcing Linux to mount the disc as UDF. It should then give you the correct size.

Good luck.

Randy,
Thanks, I will try that. Idea

Any progress on the GUI problem in the latest version that I downloaded? Sad

I doubt I will have users that motivated to use the command line method to burn DVD's, unless forced by a sharp object. Twisted Evil

Keep me posted.
