Bye, Attila yes it works! but the chmod works only if i don't unplug usb connector..when i unplug and then plug in it, the problem came back permission...755..sigh! ...and i would like give at every users to mount, on read/wite, the udf media.... i cannot give pemission to use chmod to every user! many thanks!! bye!

excuse me, anoter little question: how i could give read write acces to every users for the new (scsi3-mmc drive...) udf (usb) media? this line (that i use whith the others media, not usb) is not sufficent: "mount -t udf -o rw,noatime /dev/pktcdvd0 /cdrw" could you helpme? many many thanks!!

Oops, I made a mistake: driver model is GSA 4040B. I done following actions: 1) in grub.conf I added hda=ide-scsi line 2) The drive is /dev/hda when I use it as CD/DVD burner /dev/scd1 when I use it as DVDRAM drive Now I am able to mount with mount -t udf /dev/scd1 /dvdram My kernel is 2.4.22 (Fedora Core 1) with UDF FS (and with UDF write support): no patch for packet writing. I tried with a disc already formatted (with Windows) and I can read/write on it but I can't see other files already presents in the disc (written under Windows): I obtain follwing messages (from dmesg) when I mount it UDF-fs DEBUG lowlevel.c:57:udf_get_last_session: XA disk: no, vol_desc_start=0 UDF-fs DEBUG super.c:1421:udf_read_super: Multi-session=0 UDF-fs DEBUG super.c:410:udf_vrs: Starting at sector 16 (2048 byte sectors) UDF-fs DEBUG super.c:753:udf_load_pvoldesc: recording time 1066770718/0, 2003/10/21 23:11 (1078) UDF-fs DEBUG super.c:763:udf_load_pvoldesc: volIdent[] = 'RAMUDF20' UDF-fs DEBUG super.c:770:udf_load_pvoldesc: volSetIdent[] = '2F55B97DRAMUDF20' UDF-fs DEBUG super.c:962:udf_load_logicalvol: Partition (0:0) type 1 on volume 1 UDF-fs DEBUG super.c:972:udf_load_logicalvol: FileSet found in LogicalVolDesc at block=0, partition=0 UDF-fs DEBUG super.c:800:udf_load_partdesc: Searching map: (0 == 0) UDF-fs DEBUG super.c:841:udf_load_partdesc: unallocSpaceBitmap (part 0) @ 2 UDF-fs DEBUG super.c:882:udf_load_partdesc: Partition (0:0 type 1511) starts at physical 272, block length 2236160 UDF-fs DEBUG super.c:1215:udf_load_partition: Using anchor in block 256 UDF-fs DEBUG super.c:1448:udf_read_super: Lastblock=0 UDF-fs DEBUG super.c:725:udf_find_fileset: Fileset at block=0, partition=0 UDF-fs DEBUG super.c:786:udf_load_fileset: Rootdir at block=139, partition=0 UDF-fs INFO UDF 0.9.6-rw (2002/03/11) Mounting volume 'RAMUDF20', timestamp 2003/10/21 22:11 (103c) and the following when I write a new file ("test.txt"): udf: unknown compression code (254) stri=my file.txt UDF-fs DEBUG unicode.c:414:udf_get_filename: Failed in udf_get_filename: sname = my file.txt The file "my file.txt" it's a file already present in disc (and written under Windows 2000): this file is not visible under Linux (perhaps the problem it's on the physical filename because it has spaces).

I have a DVD -R/+R/-RW/+RW/RAM device (LG GMA 4040B): with Linux I am be able to burn DVD-R/+R disc. Now I would like to use also with DVD-RAM disc: I inserted in my kernel (2.4.22) udf filesystem (with write support): I inserted in /etc/fstab the following line (LG device is /dev/hda, my hard disk is /dev/sda) /dev/hda /dvdram udf noauto,sync, user 0 0 but when I run mount /dvdram I obtain: mount: block device /dev/hda is write-protected, mounting read-only mount: No medium found Can you help me? Thanks in advance

anybody know how( if it is possible) to write an udf disk whith an external cd-writer usb? i'm able to format disk whith cdrwtool but when i mount the disk i'm unable to write into...everithing seem ok but doesn't wake up the red light on my writer...and so it doesn' write.... ex: /sbin/modprobe pktcdvd /sbin/modprobe udf /usr/local/bin/pktsetup /dev/pktcdvd /dev/sr1 /bin/mount /dev/pktcdvd /mnt/masterizzatore -t udf -o rw,noatime this the device propriety: [root@cosmogonia tmp]# ls -l /dev/sr1 brwxrwxrwx 1 root root 11, 1 10 nov 13:50 /dev/sr1 [root@cosmogonia tmp]# ls -l /dev/pktcdvd brwxrwxrwx 1 root disk 97, 0 10 nov 14:30 /dev/pktcdvd and this the usb recognised: usb.c: USB device 3 (ven/prod 0xecd/0x1403) is not claimed by any active driver usb-uhci.c: interrupt, status3, frame#1232 vendor: waitec model:frisbiII rev:usx1 type cd-rom ansi scsi revision:02 attached scsi cd-rom sr1 at scsi1, channel0, id0, lun0 sr1:scsi-1 drive i've tryed whith devfs too, those are the different command, but nothing change...: /sbin/modprobe pktcdvd /sbin/modprobe udf /usr/local/bin/pktsetup /dev/pktcdvd /dev/cdroms/cdrom1 /bin/mount /dev/pktcdvd /mnt/masterizzatore -t udf -o rw,noatime [vage@cosmogonia vage]$ ls -l /dev/scsi/host1/bus0/target0/lun0/cd (this is "/dev/cdroms/cdrom1") brw------- 1 vage root 11, 1 1 gen 1970 /dev/scsi/host0/bus0/target1/lun0/cd if you could give me any suggestion you'll be very appreciates!! many thanks!!

Yestardey, I have applied the Dyson patches. I have formated the DVD-RW with : growisofs -Z /dev/cdrecorder=/dev/zero (Is correct ?) and then I have build the udf fs. Ok, It works very well :-) But, I have find a big difference between a DVD-RW formatted with growisofs and one formatted with InCD (windows). The DVD-RW formatted with growisofs has one big track closed and complete ! The DVD-RW formatted with InCD has a one big track not closed and not complete ! (I have used dvd+rw-medinfo /dev/cdrecorder to see theses info) A DVD formatted with windows is readable and writable with linux. But, a DVD formatted with growisofs is unreadable with windows (InCD) Bye

Thank's for Your reply Dyson. My Box is a SuSE 8.2, kernel 2.4.21 with suse patches. I have already installed dvd-packet patches from this site http://www.pond-weed.com/dvd.html and like the Author i have an NEC 1300A. All works fine. (I can packet write CD-RW and DVD+RW, but DVD-RW doesn't work.) Probably, I have to wait for a DVD-RW path ...
