Only 517MB available when UDF is used on DVD?

Hi,

I was trying to get packets writing working on my DVD. So I follows the Gentoo Wiki. Everythings goes smoothly, except after I formated the DVD+RW and created the UDF filesystem with the following command:

Code: Select all

dvd+rw-format /dev/hda
mkudffs /dev/hda

After I mounted the UDF disk, df shows that the device only have 517MB.

Code: Select all

/dev/pktcdvd/0        517M   42K  517M   1% /media/dvdrw

dvd+rw-mediainfo shows the following info.

Code: Select all

# dvd+rw-mediainfo /dev/hda

I even tried to forcefully reformat the disk again, and create the udf structure again by:

Code: Select all

mkudffs --media-type=dvd /dev/hda

But it yields the same result. Does anyone have any ideas what is going on? Is it because UDF is not supported on DVD+RW? Thanks.

Have you tried copying something to the disc?

Nope. it was blank. But I cannot mkudffs if I don't format it again. However, I can burn 4GB of data if I am use K3B for regular DVD burning. So I believe it is a problem with mkudffs. How can I make mkudffs format my DVD properly?

No I didn't mean like that. I meant that you should try to copy some files to the disc and see if you can fit some more than those ~500 MiB...

I tried. I can't copy more than 517MB to the DVD. However, the interesting thing is, after I copyed 1GB of data to the DVD via K3B (i.e. to regular way instead of just copying the file to the disk), the legancy lead-out becomes 1GB. Then, if I do mkudffs /dev/hda again, I have 1GB of disk space. Does that mean I have to copy 4GB of data to the DVD before I format it with mkudffs?

I had something like that a long time ago, and I believe I fixed it by using

Code: Select all

dvd+rw-format /dev/hdc -force

followed by mkudffs..

Tried it. But my legacy lead-out is still at 1GB and the file system created with mkudffs afterward is still at 1GB. Are you sure that command is what fixed the issue?

BTW, I think it is supicious that the command

Code: Select all

dvd+rw-format /dev/hda -force

only takes 5 seconds to complete.

Just tried -force and it took approx 40 seconds here, mkudffs went faster, and Kdiskfree shows 4.4GB available after mounting it.. if you have the possibility it might be an idea to test your dvd+rw media with some XP tool. Around the time of my problems, a number of my old media tested faulty..
Btw my mkudffs output is

Code: Select all

mkudffs /dev/pktcdvd/dvdwri
start=0, blocks=16, type=RESERVED
start=16, blocks=3, type=VRS
start=19, blocks=237, type=USPACE

I can run mkudffs fine, but my output is different from yours:

Code: Select all

# mkudffs --media-type=dvd /dev/hda
start=0, blocks=16, type=RESERVED 
start=16, blocks=3, type=VRS 
start=19, blocks=237, type=USPACE

My DVD+RW disk is from Sony? So far, all of them that I have formated will only have 517MB of space. Are they unreliable?

On the other hand, are XP too software that that runs on Windows XP only? Unfortunately, I don't have Windows XP. I have Chinese Windows 95 though, but it is used on my Dad's Pentium PC already. Is it possible to forcefully adjust the legacy lead-out? I believe it is the lead-out problem.

I would try a disk from another batch of dvd+rw, and if that doesn't help, it could be an idea to update your drive's firmware and try again. http://club.cdfreaks.com/showthread.php ... ght=DW1620

I just tried it on my LiteON DVD Writer. It can relocate the lead-out properly and the formated UDFFS under LiteON DVDWriter is 4GB. So, I believe BENQ's DVD writer is buggy >_<. And the BENQ DVD-Wrtier does not support Mt. Rainer. I guess I will not buy from BENQ again until they fixed up their product.

BTW, I am already using the latest firmware on both DVD Writer. Thanks a lot for the help.
