I am trying to make ext3 file system on DVD+RW media but getting "Read-only file system" error. First I formated the DVD:
| Code: | root@romanus dev # dvd+rw-format -force /dev/dvd
* DVD±RW/-RAM format utility by <appro@fy.chalmers.se>, version 4.10.
* 4.7GB DVD+RW media detected.
* formatting - |
And next I tried to apply the file system:
| Code: | root@romanus dev # mke2fs -j /dev/dvd
mke2fs 1.35 (28-Feb-2004)
/dev/dvd: Read-only file system while setting up superblock |
Additional info:
| Code: | root@romanus dev # ls -l /dev/dvd
lrwxrwxrwx 1 root root 3 Feb 14 23:37 /dev/dvd -> hdc
root@romanus dev # ls -l /dev/hdc
brw-rw-rw- 1 promanus root 22, 0 Feb 18 2004 /dev/hdc |
Appologize if this a newbie question  This area is new to me...

| As far as I know, you can't format removable media like this (DVD-R/W and CD-R/W) because they have their own setup (don't ask me what - I'm speaking just from my limited knowledge, although the letters ISO9660 keeps coming up). Also, you need a tool that is specifically designed to write to a CD - mke2fs was not designed for this purpose. And, as it points out to you, the DVD is only a readable mediums (as far as it is concerned). |

| IIRC, to burn dvds you use growisofs. |

I have seen posts in various places suggesting that this is possible.

Thanks for your help. Would you happen to know if the support for packet cd writing is in 2.6.9 kernel? I could not find it in 2.6.9 
UDF support on the other hand is already enabled in my kernel.
Do you know any tools that can format DVD+RW media with UDF?

Where? Is this a kernel option that I can enable? Is it under "Device Drivers"?

Never mind. I see it in 2.6.10-gnetoo-r6. It is under
| Code: | Device Drivers --->
Block devices ---> |
2.6.9-gentoo-r8 does not seem to have it. Unless it is somewhere else...
