Thank you Freddie, I will try it out!! :-) UDF disk does not work on FreeBSD :-( I can create filesystem on a file, but not a memory disk (not supported on my operating system yet). Then I cannot mount both of them anyway. Dead end for UDF disk on FreeBSD? Is seems possible on Linux and Windows though: http://tanguy.ortolo.eu/blog/article93/usb-udf root@hexagon:~ # dd if=/dev/zero of=udf.bin bs=64k count=128k 131072+0 records in 131072+0 records out 8589934592 bytes transferred in 111.747670 secs (76869026 bytes/sec) root@hexagon:~ # newfs_udf -L UDFTEST udf.bin Opening device udf.bin UDF device udf.bin is a regular file bufcache thread initialising Disc info for disc in device udf.bin MMC profile : Unknown[0] profile sequential : no recordable : yes erasable : no blankable : no formattable : no rewritable : yes mount raineer : no packet writing : no strict overwrite : no blocking number : 1 disc state : random writable last session state : incomplete sectorsize : 512 Number of sessions 1 Session 0 start at 0 ends at 16777216 length for 16777216 next writable at 16777217 free blocks 0 packet size 64 Creating a filingsystem on a recordable rewritable CD-RW or DVD+RW/DVD-RW or fixed length file Free unallocated space on this volume 8587442688 Closing disc Dismounting disc syncing disc syncing `4dc9e13a`:`00001674`:`UDFTEST` syncing data syncing nodes used/freed space tables Closing logical volume `4dc9e13a`:`00001674`:`UDFTEST` wait for syncing disc to idle stopping bufcache thread bufcache thread joining signal disc its finished with writing wait for final disc idling close device Disc access statistics sector reads 1 (0 Kbyte) sector written 4267 (2133 Kbyte) switches 3 root@hexagon:~ # dd if=/dev/zero of=udf2.bin bs=64k count=8k 8192+0 records in 8192+0 records out 536870912 bytes transferred in 7.191754 secs (74650899 bytes/sec) root@hexagon:~ # mdconfig -a -f udf2.bin md0 root@hexagon:~ # newfs_udf -L UDFTEST2 /dev/md0 Opening device /dev/md0 Got error executing SCSI command, assuming IDE disc UDF: no explicit support for disc devices yet for this operating system. : No such file or directory Trying readonly access... : No such file or directory UDF: warning... reading/writing on 'disc' device bufcache thread initialising Disc info for disc in device /dev/md0 MMC profile : Unknown[0] profile sequential : no recordable : no erasable : no blankable : no formattable : no rewritable : no mount raineer : no packet writing : no strict overwrite : no blocking number : 1 disc state : random writable last session state : complete/closed disc sectorsize : 512 Number of sessions 1 Session 0 start at 0 ends at 0 length for 0 next writable at 0 free blocks 0 packet size 0 Can't create filingsystem on a non recordable disc Closing disc Dismounting disc dismounting readonly disc stopping bufcache thread bufcache thread joining Disc access statistics sector reads 0 (0 Kbyte) sector written 0 (0 Kbyte) switches 0 root@hexagon:~ # mount_udf -v /dev/md0 /mnt/tmp mount_udf: /dev/md0: Invalid argument root@hexagon:~ # mdconfig -d -u 0 root@hexagon:~ # mount_udf -v udf.bin /mnt/tmp mount_udf: udf.bin: Invalid argument root@hexagon:~ # mdconfig -a -f udf.bin root@hexagon:~ # mount_udf /dev/md0 /mnt/tmp mount_udf: /dev/md0: Invalid argument Did I miss anything? :-( -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
