diskutil rename error: "does not appear to be a valid volume name for its file system"

I'm trying to rename the volume name of a mounted ISO image using the command:

diskutil rename /dev/disk15  TEST_DISK_2014_RENAMED

I get the error:

TEST_DISK_2014_RENAMED does not appear to be a valid volume name for its file system

I tried running this with sudo with the same results.

$ diskutil info /dev/disk15:

$ bash --version:

Variations:

diskutil rename TEST_DISK_2014  TEST_DISK_2014_RENAMED
diskutil rename /Volumes/TEST_DISK_2014  TEST_DISK_2014_RENAMED
diskutil rename /Volumes/TEST_DISK_2014  /Volumes/TEST_DISK_2014_RENAMED
/Volumes/diskutil rename TEST_DISK_2014  "TEST_DISK_2014_RENAMED"
diskutil rename TEST_DISK_2014  'TEST_DISK_2014_RENAMED'
diskutil rename 'TEST_DISK_2014'  'TEST_DISK_2014_RENAMED'
diskutil rename "TEST_DISK_2014"  "TEST_DISK_2014_RENAMED"

Nothing works.

So what's the story? What is the proper syntax? I could find no other examples.

That's really kludgy. I'd much rather learn do it with diskutil or some other OS X tool. – hmj6jmh – 2014-11-11T22:58:38.237

I tried that script but it didn't change the volume name. It wrote the new name in the specified location but I don't know what it did to the data. In a hex editor, the volume name occurs multiple times in different locations. – hmj6jmh – 2014-11-12T04:48:16.540

In any case, it's not a good idea to mess with the data like that. I think the problem is the ISO format is read-only. Is there a way to make it read-write without making a copy? – hmj6jmh – 2014-11-12T05:08:01.313
