Mac UFS partition unreadable

[Bram Van Steenlandt]

Hi,

I use both mac and freebsd and would like to have the abbility to use my 
external firewire drive on both plattforms.

This should be possible because both are BSD and both can use UFS.
However when I plug an freebsd formatted drive into my mac he is rather 
confused by first saying that he can't read this drive and I should 
format it. Then when I try to mount it from the terminal he complains 
about the superblocks, when I run some utils they sometimes say they 
can't determine the partition type, also when I look into /dev there is 
nothing that indicates that this drive has partitions.

So I formatted the drive on my mac into UFS. Same thing happens on 
freebsd. I did some googling and it appears to be so that this could be 
because of little vs big endian. I am however rather new to freebsd and 
have no idea what the difference is.

So what can I do to have a drive readable to both OSes ?
note:
drive is 160 Gig seagate
mac is running 10.3.5
freebsd is amd 64 5.3 RELEASE

mac supported disk formats are
MS-DOS,UFS,HFS,HFS+
I now that HFS or MS-DOS would work but then I have no support for 160 
gig / long filenames

I'm out of inspiration

Thanks In advance

Bram
