Anytime a file system is not unmounted properly you'll get some 
quantity of errors from fsck the next time the system tries to mount 
it.  If there was no activity on the file system, fsck can typically 
deal with things on it's own.  When there were open files and some 
level of activity on the file system, you'll get the types of errors 
that you are seeing now. Most of the time, just saying yes to 
everything will work just fine, and you can move on.  fsck -y will 
keep you from having to actually type 'y' at each prompt, which is 
handy because sometimes there are a lot of those prompts.

There's a port that will allow you to read hfs filesystems.  It's in 
/usr/ports/emulators/hfs
