Hi Tom, Karl and All,<br><br> Yes Tom. Ubuntu 9.10 Desktop CD has the "nodmraid" boot option (press F6 before boot).<br><br> I could now see and use all my internal and removable disks. Thanks.<br><br> One more point I want to be clear. If, later, I want to install Ubuntu 9.10 Desktop into my non-raid sda1 or sda2 partition. Should I first boot the Ubuntu 9.10 Desktop CD with the "nodmraid" boot option and then install; or should I first boot the Ubuntu 9.10 Desktop normally, apply the command "apt-get purge dmraid" and then install ?<br>
<br> Happy to have your helpful comment.<br><br>Regards<br>Lawrence<br><br><br><div class="gmail_quote">On Tue, Feb 2, 2010 at 9:50 PM, Tom H <span dir="ltr"><<a href="mailto:tomh0665@gmail.com">tomh0665@gmail.com</a>></span> wrote:<br>

</div>dmraid -a n will definitely not touch your data but I think that there<br>
is another solution but cannot check.<br>

When you boot from the Ubuntu live cd, you can choose some kernel<br>
options with one of the f-keys. nodmraid might be one of them.<br>
