42 Actual error messages please :-)
44 Let's start with what is in dmesg.
46 You also mention /dev/hda and the context implies it is a physical disk.
47 Unless you have ancient disk hardware and unusual module setup, your disks
48 will be /dev/sda. Do you have references to /dev/dh** in /etc/fstab? That
49 won;t work as udev will not name them that way
