>Description:
	When a system with a SCSI disk drive with removable media is shut
	down, the SCSI cache sync code generates a dire-sounding warning
	about cache sync failure if there is no disk in the drive.

>How-To-Repeat:
	Halt a system having an Iomega Jaz 1 GB drive with no disk inserted:

	  sd1(ncr0:1:0):  Check Condition on opcode 0x35
	      SENSE KEY:  Not Ready
	       ASC/ASCQ:  Medium Not Present

	  sd1: WARNING: cache synchronization failed

>Fix:
	Perhaps it would be straightforward to examine the reason for
	failure, and suppress the warning if the reason is
	"Medium Not Present."
