I've found that sometimes the installer gets a bit confused if
you start an installation, it goes wrong or you decide to start
again and it forgets you already have devices mounted.

Also worth noting (but I downloaded the ISO so never saw the problem):

As shipped, the "Custom" installation option in 3.4 is broken
and menu items like Configure don't work

Fix: Both the "Novice" and "Express" install paths still work and
     can be used just as effectively (if not succinctly).  Alternately,
     you can invoke the custom installation from the "Index" menu
     (Installation, Custom) along with the Configuration option.  You
     can also just download a fixed mfsroot.flp floppy image (or boot.flp
     if you need 2.88MB boot media) from the following URL:

     The 3.4 ISO installation image is also updated to contain fixes
     for all these errata items.

I don't think this is a hardware problem, this is an installer issue,
the mount of the newly created filesystem is failing.
