    how do rw permissions on partitions extend across Os'es

    i did a fresh install of hardy on sdb today and after it was set up I created 3 new partitions, 2 ext2 and 1 fat32. While i could immediately mount and unmount all 3 with l.click, r.click, only the fat32 could be written to. So i created a temp dir. to mount, chown the ext.2's as below which gave me the write permissions to them.

    sudo mkdir /media/fix
    sudo mount /dev/sdb5 /media/fix
    sudo chown doug:doug /media/fix
    sudo umount /dev/sdb5 /media/fix
    sudo mount /dev/sdb7 /media/fix
    sudo chown doug:doug /media/fix
    sudo umount /dev/sdb7 /media/fix
    sudo rmdir /media/fix
    When i booted into gutsy on sda I was surprised to see that I could write to the 2 new ext2's without doing anything.

    Do the permissions/ownership 'stay' with the partitions?
