Re: [Banshee-List] why can't Banshee write to HFS+ iPods?

["Adam Dingle" <adam medovina org>]

Aaron,

Yes - Ubuntu 7.04 comes with HFS+ write support enabled out of the box; I didn't have to install anything extra to make it available.  I'm running a 2.6.20 kernel (specifically, the Ubuntu kernel 2.6.20-15-generic ).  The HFS support is in the kernel module hfsplus.ko, which is included in the linux-image-2.6.20-15-generic Ubuntu package.  I believe that this binary is built from from the HFS+ kernel module in the sources at kernel.org, which in turn presumably emanates from the linux-hfsplus sourceforge project.

I've attached output from hal-device as you requested.

I can't really say much about the stability of HFS+ writing at this point, but as I said it seems to be working for me now.  I did have to disable journaling on the iPod's HFS+ partition, and I also ran "chmod -R go+w /media/ipod " to turn on write permissions for all directories.  Since I've got this working I'm willing to be a guinea pig and keep using this for a while; I'll let you know if I run into problems.

After a little searching, I am not convinced that solid HFS+ support
exists. Not much has happened in the hfsplus kernel module:

And google doesn't say much, other than a page from Gentoo:

Does Ubuntu include the HFS+ module from the linux-hfsplus project on
sourceforge?

http://sourceforge.net/projects/linux-hfsplus

Did you install something separately to get write support? AFAIK, and
also as pointed out by the Gentoo page, the HFS+ write support that
exists in some forms is very unstable and journaling isn't supported at
all - and iPods come with journaling enabled by default.
