The current (?) version of /sys/src/boot/pc/sdscsi.c has the
following in :/^scsiverify:

		if((r->sense[2] & 0x0F) != 0x02)
			continue;
		if(r->sense[12] == 0x3A){
			status = SDok;
			break;
		}

as opposed to, in /sys/src/9/pc/sdscsi.c:

		if((r->sense[2] & 0x0F) != 0x02)
			continue;
		/*
		 * Unit is 'not ready'.
		 * If it needs an initialising command, set status
		 * so it will be spun-up below.
		 * If there's no medium, that's OK too, but don't
		 * try to spin it up.
		 */
		if(r->sense[12] == 0x04 && r->sense[13] == 0x02){
			status = SDok;
			break;
		}
		if(r->sense[12] == 0x3A)
			break;

Sadly, my controller seems to return

                r->sense[12] == 0x04 && r->sense[13] == 0x01

and I have no idea what to make of it :-(

Suggestions?  I can't find my SCSI reference manual, so I'ma bit at
the mercy of the list.  Oh, the problem I'm trying to address is
9load's inability to use #S/sd00/9fat/plan9.ini.
