Don't you have to reboot to change OS's? No re-booting is necessary when running Centos 5.5. Besides I am 'lazy' and hate re-booting because it so time wasting. On one machine running Centos 5.5 I have in /etc/fstab /dev/sda5 /nos.f14 ext4 auto 0 0 /nos.f14 is a pre-created, but empty, directory used as the mounting point for, in this instance, Fedora 14. On another machine (the tri-boot machine) I also run Centos 5.5 and in that /etc/fstab I have /dev/sda3 /z-vista/ ntfs-3g auto,umask=0000,defaults 0 0 /dev/sda7 /z-fedora/ ext4 defaults 1 2 The z-vista and z-fedora are empty root directories used as mounting points. Obviously you can use any name you prefer. Being honest I have to point-out that I can not remember what the 0 0 or the 1 2 actually mean. It works. I can access and change the Vista 'drive' contents and the also the entire Fedora 'drive'. If I wanted to access, on that machine, Vista's two extra drives (System & Resources) then I would add to /etc/fstab something like /dev/sda1 /z-system/ ntfs-3g auto,umask=0000,defaults 0 0 /dev/sda2 /z-resources/ ntfs-3g auto,umask=0000,defaults 0 0 Hope that helps.
