Is that *exactly* what it prints out?  There's usually more information.

In any case, asc,ascq 0x25,0x00 means "Logical unit not supported".  It
sounds like the drive has pretty much lost its brain, and doesn't think it
has a LUN 0 anymore.

You might try looking for updated firmware for the Fujitsu disks, or maybe
Justin or Scott will have some insight into what's going on here.

You could also try a newer release.  There have been a number of changes to
the aic79xx driver recently.

The latest snapshot ISO image is here:

You could also just try grabbing the boot floppy images from that release
and see how they work:
