I have a Mac laptop. I usually use Ubuntu Linux on it, but I want to start actually using Mac OS X. I want to have a volume that can be mounted read/write in both OS X and Linux.
I just upgraded to Snow Leopard, and while I did that, I created a new volume. Using Linux tools, I formatted the new volume to HFS (not HFS+). I then verified that Ubuntu would mount it, and that I could write to it.
Now that I'm booted back in to Mac OS X Snow Leopard, the volume automatically mounts, but only as read-only. And while I'm an expert in Linux I'm a total newbie in OS X.
How can I mount the HFS volume as read/write? How can I ensure that it will always mount read/write on every reboot?
I want to rename the HFS volume from "untitled" to "Mac Home". diskutil fails with a strange error ("Failed to rename volume: Invalid request (-9998)"). I suspect that the problem is that the volume is mounted read-only; if I can mount it read/write I hope this command will work. Or, if it is read/write, maybe I can rename it in the Finder?
Thank you for any help.
