Arch Linuxでhfs +パーティションをマウントすると問題が発生します。
実行するsudo mount -t hfsplus /dev/sda2 /mnt/mac
と、次のエラーが表示されます。
mount: wrong fs type, bad option, bad superblock on /dev/sda2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
実行すると以下dmesg | tail
が得られます。

このパーティションをマウントする方法はありますか?
編集:
使用sudo mount -t hfsplus -o ro,loop,offset=409640,sizelimit=879631488 /dev/sda2 /mnt/mac
を取り除くhfsplus: invalid secondary volume header
でdmesg | tail
