Unable to mount partition...

Hi all,
Newbie boy here ...
I have a problem which did not occur last time I did this with the same hardware, but redoing the job has presented itself.

Okay, booted off the emulator disk and installed this to the harddrive as per the guided setup instructions with no problem.
Then had to install cachecard drivers - so wrote these to a floppy, and booted off the nic_install CD as stated on the Silicondust site.

After part 7, I get the following error...

"Error - unable to mount partition "/dev/hdc9" (22)"

(this is set up with the CDrom drive as the primary master, and the new HD as the secondary master).

Any idea's on this one ?
Ive repeated the whole process and still get this....
