How dangerous is HFS+ in FreeBSD 5.3?

[Timothy Luoma]

I have an external 60GB Firewire drive currently (stupidly) formatted 
in HFS+ (Mac OS X "Extended").  I'd like to get all the files off of 
the drive and onto my FreeBSD machine (which has firewire card 
installed, although I've yet to try and tackle mounting it).

http://people.freebsd.org/~yar/hfs/ was the place to turn, but there 
are several very ominous warnings about using it for important data.  I 
was curious as to whether this was just one of those "cover your 
behind" disclaimers or a "really, don't use this for anything 
important" disclaimers.
