    Re: no drives found?

    I'd definitely check the physical connection, but it sounds like the drive is dead. You could try burning gparted to a live cd and see if it picks it up.

    Looks like we are back to trying to zero out the disk with dd .... here goes
    I suggest that you look at the manual " man dd " in terminal . This command is awesome but very powerful and will destroy if used in a inappropriate manner.
    OK
    From the live cd (so your devices are not mounted) in terminal paste/copy this:
    Code:
    sudo dd if=/dev/zero of=/dev/sda bs=1M
    this command sequence is for only one drive installed (hence /dev/sda).
    There will be no echo to the terminal of any output (work-around-below) until finished.... will take a long time ... my 500G drive took 2 hours to complete.

    here is the way to get a status on "dd"

    open up another terminal and enter this code:
    Code:
    ps -ef | grep dd
    in this result look for the line that designates dd's process ... NOT the process of the grep for dd's process...you will need the process numbers from the first column (this is the pid).
    ok ?
    enter this code in the same (#2) terminal:
    Code:
    sudo kill -SIGUSR1 <the pid number>
    without the brackets in the above, just to show what/where to place pid.

    the output from this terminal will be in your first terminal after a bit of number crunching... In 'bout an hour input the above again to get updated status...

    when done see if Gparted from the live cd will see the disk and then install a great operating system and enjoy!

    Re: no drives found?

    ok so based on your time of 2 hours im guna say something went wrong. heres what i have from terminal 1

    Code:
    To run a command as administrator (user "root"), use "sudo <command>".
    See "man sudo_root" for details.
    
    ubuntu@ubuntu:~$ sudo dd if=/dev/zero of=/dev/sda bs=1M
    dd: writing `/dev/sda': No space left on device
    240+0 records in
    239+0 records out
    250974208 bytes (251 MB) copied, 19.7607 s, 12.7 MB/s
    ubuntu@ubuntu:~$
    and i ran the command to see the progress and got this

    Code:
    ubuntu@ubuntu:~$ ps -ef | grep dd

    Kickin ...
    the output from dd is as shud be upon completion of zeroing out the disk......

    uuuhhh I hope it ran about 20 minutes...if the dd command had finished then the kill command had nothing but garbage in ... is this what happened ??? I hope!

    Re: no drives found?

    This might be off the ball but are you sure you're attempting to install Ubuntu, desktop or alternative, and not Wubi, which is intended for installation inside Windows?

    If you don't have Win up and running, it will be impossible to install Wubi, if this is the scenario.

    Re: no drives found?

    heres how it went down. i started the dd comand. as you can see it only took about 19 seconds to complete. i then checked the progress with a second terminal. (also posted the results. i havent killed the process yet because im unsure of the PID. i tried looking up some more info to help me out but honestly it might as well be written in russian
