Umounting should be good enough, but you can also use eject(1), which should have the desired effect, e.g: # disklabel sd1 # /dev/rsd1c: type: SCSI disk: SCSI disk label: Flash Disk ... # eject /dev/rsd1c # disklabel sd1 disklabel: DIOCGDINFO: Input/output error # You'll need to physically reconnect the drive if you want to use it again. -Bryan.
