I had a question from someone at work regarding sharing an external disc between Windows and Mac systems. Having briefly considered my options I came to the conclusion that FAT32 with all it's drawbacks is the only option.

Now, I've just bought a new external HD myself as my myth backend (and fileserver) is making some rather horrible noises and I haven't the money for a nice terabyte nas with off site duplicity backup right now. So I'm just backing up the server and putting the disk in the safe at work.

Looking through the options in the kernel of the myth box there is support for HFS+ which means I could back up from the linux box and then read it on the Mac. However formatting it as HFS+ and trying it on the box (2.6.12) has resulted in an unmountable volume. Windows compatibility is less important for this drive, but I'm thinking FAT32 is probably the answer for this one too.

Any ideas?
