My fstab output doesn't show my slave!!!!!

hi guys! after spending 2 days (48hours) figuring out how to format, partition, mount and to change permission to a slave drive, I found out that I don't see my slave drive in the fstab output, was going on!!
I just want to find a logic on this system.
this is some information:

desktop:~$ sudo fdisk -l
Password:

Disk /dev/hda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders

FSTAB OUTPUT:

# /etc/fstab: static file system information.

# /dev/hda1

/dev/hdd /media/cdrom1 udf,iso9660 user,noauto 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0

Every time I reboot my slave, it mounts and i can read and write to it, and now i sooo happy that i want to know what happened so i can help another newbie.

As you see the fstab output, there is not any slave (hdb1) mounted
I hope you will help me with this one too.

you can manually mount (make accessible) your slave with shell commands

Code:

su (and passwd)
mkdir /mnt/slave
mount -t ext3 /dev/hdb1 /mnt/slave

change /mnt/slave to anything you like and I am assuming you formatted slave same as master as ext3.

if your file manager navigates ok then add a line to fstab so it automatically mounts on bootup

fstab entry (style dev)

/dev/hdb1 /mnt/slave ext3 defaults 0 2

2) but if you prefer uuid style you will need to look at /var/log/syslog after manually mounting to see what uuid is reported.

Thanks AUS9: that helped me a lot but now when I try to see my etc/fstab, I got this:

desktop:~$ /etc/fstab
bash: /etc/fstab: Permission denied
-desktop:~$

I'm the only owner, user and superuser of this system so, what did I do wrong?

You need to edit the file with a text editor (and will need root permissions to do so - use sudo as you did with fdisk). Simply typing "/etc/fstab" at the prompt tells the shell to execute /etc/fstab (as if it were a binary, or a script for example). You get that error because executable permissons aren't set on the file, which makes sense given what I've said in the last sentence. If you want to read plain text files on the command line, you can use "cat" (which concatenates files and prints them, but will print a single file to standard output) or a pager like "more" or "less".
