admin login problems

Created "admin" account on install (or i thought i did) but Ubuntu locks everything and will not let me change anything or write to my two storage drives. What could be wrong ?????

The installer is the admin acount

If user fred installed ubuntu, then the install puts fred in the admin group. In order to do anything admin-ish, you need to prefix the command with sudo, and respond with fred's password.

As to the other things you cannot do, it would help to split each problem out and have some more detail.

admin problems

i understand that i am supposed to be in the admin group but i dont seem to have admin premissions.

i have installed several programs using the sudo command and it does exactly what it is supposed to.

The thing is this, i have 3 drives in the machine ---

40 gig is the OS

160 for storage
160 for storage

the 40 gig seems to be ok as in i can rw to it in the "home" directory, but anything else it seems that i dont have to right to make any changes.

Formated one of the 160 gig drives ok, but it set it to read only and i can not change the premissions, says i dont have premission to do that.

Found a file (fstab) where i can go in and change it but it wont let me save it, says i dont have premission to do this.

editing the /etc/fstab file is the right way to go. kudos to you for finding that! it's a protected system file, so you need to use sudo to edit it. how are you opening it right now? here are some examples (all from the command line):

sudo pico /etc/fstab
sudo nano /etc/fstab
sudo vim /etc/fstab
sudo emacs /etc/fstab

personally I use vim, but a lot of people find pico or nano easier to get the hang of.

once you have the file open and can make changes, you need to find the line(s) that refer to the filesystem you want to change. usually the format is:

device     mount     type     options
you need to add "users" to the options. for example, here is a windows fileshare that I mount automatically when my computer boots:

//$         /mnt/windows            cifs    credentials=/home/mcd/.cifscreds,users  0 0
don't worry about most of that, but the "users" at the end is what gives my user account permission to add, remove, and change files. post up if you run into more trouble.
