You have to be sure to "Install full" the disk; I had problems getting
6.0.5 to deal with 128K ROMs until I did.

If you want to get the hard disk back, probably boot from floppy and
possibly use one of the multifarious disk fixers.  Norton's was at
work and saved a Syquest removable yesterday - slick and quick!  The
drive was fine but the directory kept getting worse.

I also found that I had to run the Hard Disk utility to reformat my
20MB (SCSI) drive before:  a) my Portable could access it at all; 
and b) I could use it with System 6.0.5.

I realize that you are using the floppy-port "Hard Disk 20" - I
could plug mine in to see but I took it out of the loop a couple of
weeks ago.

Just try sticking in "System Tools 6.0.5" into the floppy drive when
you power up to boot from floppy and use the Installer to put up a
"complete" set of the system software.  It works fine now, here.

There is also a cdev called "SCSI Probe" which like some similar
utilities goes off and mounts an unmounted SCSI device.

Have fun.
