Several time recently I've seen UDF suggested as the solution to a cross platform format for a drive used on Linux, Mac OS X and Windows XP and above.
I've searched here and not found the same suggestion (most are suggesting ntfs-3g which seems to cost money and isn't preinstalled on a Mac).
So my question is: how is this done right, and has anyone done this? Have you then filled up the drive and deleted some files to make space finding that everything works like a real r/w format even though it seems to have been primarily a write once format?
Call me crazy but I'd really like it if the UDF system would also automount and be writable by the logged in user. What I've tried so far (udftools formatting as mentioned by kicsyromy) doesn't address this wish.
