I have formated a 2TB external disk with UDF filesystem in Ubuntu. The way I formatted it was:

   sudo dd if=/dev/zero of=/dev/sdc bs=2048 count=1
   sudo mkudffs --media-type=hd --vid=myDisk --blocksize=2048 /dev/sdc

Now I plug the disk in OSX and nothing is automount. The disk is recognized, but nothing else, it's not mounted. I am in OSX Snow Leopard 10.6.8.

diskutil list shows:

 #:                       TYPE NAME                    SIZE       IDENTIFIER
 0:                                                   *2.0 TB     disk2

So first problem is that it doesn't recognize the TYPE NAME is defined in format option (--vid=myDisk). Anyway....

I tried to mount the disk manually:

   sudo mkdir /Volumes/myDisk
   sudo mount -v -t udf /dev/disk2 /Volumes/myDisk/

And I get:

 mount_udf: /dev/disk2 on /Volumes/myDisk: Device not configured

If I try:

 diskutil mount  -mountPoint /Volumes/myDisk /dev/disk2

I get

 Volume on disk2 failed to mount; if it has a partitioning scheme, use "diskutil mountDisk"

If I try:

 sudo mount_udf -b 2048  /dev/disk2 /Volumes/myDisk/

I get

   mount_udf: /dev/disk2 on /Volumes/myDisk/: Device not configured

Any ideas? Thanks in advance

You didn't partition the disk, that is, you created the filesystem on /dev/sdc instead of /dev/sdc1. Not sure if that's a problem on OS X, but you may want to create a partition /dev/sdc1, create the UFS filesystem and try again. – jaume Jul 5 '13 at 12:26
