.Sh EXAMPLES
.Bd -literal -offset indent
device umass
device scbus
device da
device pass
.Ed
.Pp
Add the
.Nm
driver to the kernel.
.Pp
.Dl "camcontrol rescan 0"
.Pp
Rescan a Zip drive that was added after boot.
The command above
assumes that the Zip drive is the first SCSI bus in the system.
.Bd -literal -offset indent
camcontrol rescan 0:0:0
camcontrol rescan 0:0:1
camcontrol rescan 0:0:2
camcontrol rescan 0:0:3
.Ed
.Pp
Rescan all slots on a multi-slot flash reader, where the slots map to separate
LUNs on a single SCSI ID.
Typically only the first slot will be enabled at boot time.
Again, this assumes that the flash reader is the first SCSI bus in the system.
.Bd -literal -offset indent
disklabel -w -r da0 zip100
newfs da0c
mount -t ufs /dev/da0c /mnt
.Ed
.Pp
Write a disklabel to the Zip drive (see
.Nm vpo

.Pp
.Dl "newfs_msdos /dev/da0"
.Pp
Create a new FAT type file system.
