    I formatted an USB stick as UDF with MBR (for compatibility) using diskutil partitionDisk.

    But when I reinsert it and tries to mount, the system shows an error saying it cannot recognize it.

    Is there any way of making this work?

    Thanks

    That's such an odd format, why not just fat32?

    I could make a read-only volume with hdiutil and dd, but I don't know how to make a writable volume that can be mounted.

    Also, dd is very slow.

    Use disk utility to format the drive as MSDOS, which is FAT32, that should be compatible with just about everything.

    Just curious, why are you obsessing over udf and doing this through terminal?

    That's easy:

    1. UDF is a universal file format that does not have a 2 GB file size limit like FAT32

    AND

    2. There doesn't seem to be a GUI tool out there for Mac OS X that formats in UDF

    Has anyone found anything other than the CLI tools? I just bought an 8 GB USB stick and want to format it as UDF so I can use it anywhere as I move some very large files from time-to-time and hate wasting a DVD+R DL.
