</question>
<answer>
<para>Whether it is a removable drive like a &iomegazip; or an
EZ drive (or even a floppy, if you want to use it that way),
or a new hard disk, once it is installed and recognized by
the system, and you have your cartridge/floppy/whatever
slotted in, things are pretty much the same for all
devices.</para>
<para>If the drive already has a
file system on it, you can use a command like this:</para>
<para>(this section is based on <ulink
url="http://www.vmunix.com/mark/FreeBSD/ZIP-FAQ.html">Mark Mayo's ZIP FAQ</ulink>)
</para>
<screen>&prompt.root; <userinput>mount /dev/da0s1 /mnt</userinput></screen>
<para>If it is a ZIP drive or a floppy, you have already got a
DOS file system on it, you can use a command like this:</para>
<para>If the drive will only be used with &os;
systems it is better idea to
stick a BSD file system on it, like UFS or ZFS.
You will get long filename
support, at least a 2X improvement in performance,
and a lot more stability. If the drive will be
used by other operating systems a more portable
choice, such as msdosfs, is better.</para>
<screen>&prompt.root; <userinput>mount -t msdosfs /dev/fd0c /floppy</userinput></screen>
<screen>&prompt.root; <userinput>dd if=/dev/zero of=/dev/da0 count=2</userinput>
&prompt.root; <userinput>gpart create -s GPT /dev/da0</userinput>
&prompt.root; <userinput>gpart add -t freebsd-ufs /dev/da0</userinput></screen>
<para>if it is a floppy, or this:</para>
<para>Finally, create a new file system:</para>
<screen>&prompt.root; <userinput>mount -t msdosfs /dev/da2s4 /zip</userinput></screen>
<para>for a ZIP disk with the factory configuration.</para>
<para>For other disks, see how they are laid out using
&man.fdisk.8; or &man.sysinstall.8;.</para>
<para>The rest of the examples will be for a ZIP drive on
<devicename>da2</devicename>, the third SCSI disk.</para>
<para>Unless it is a floppy, or a removable you plan on
sharing with other people, it is probably a better idea to
stick a BSD file system on it. You will get long filename
support, at least a 2X improvement in performance, and a lot
more stability. First, you need to redo the DOS-level
partitions/file systems. You can either use &man.fdisk.8;
or &man.sysinstall.8;, or for a small drive that you do not
want to bother with multiple operating system support on,
just blow away the whole FAT partition table (slices) and
just use the BSD partitioning:</para>
<screen>&prompt.root; <userinput>dd if=/dev/zero of=/dev/rda2 count=2</userinput>
&prompt.root; <userinput>disklabel -Brw da2 auto</userinput></screen>
<para>You can use &man.disklabel.8; or &man.sysinstall.8; to
create multiple BSD partitions. You will certainly want to
do this if you are adding swap space on a fixed disk, but it
is probably irrelevant on a removable drive like a
ZIP.</para>
<para>Finally, create a new file system, this one is on our
ZIP drive using the whole disk:</para>
<screen>&prompt.root; <userinput>newfs /dev/rda2c</userinput></screen>
<screen>&prompt.root; <userinput>newfs /dev/da0p1</userinput></screen>
<para>and mount it:</para>
<screen>&prompt.root; <userinput>mount /dev/da2c /zip</userinput></screen>
<screen>&prompt.root; <userinput>mount /dev/da0s1 /mnt</userinput></screen>
<para>and it is probably a good idea to add a line like this
<para>It is a good idea to add a line
to <filename>/etc/fstab</filename> (see &man.fstab.5;) so
you can just type <command>mount /zip</command> in the
you can just type <command>mount /mnt</command> in the
future:</para>
<programlisting>/dev/da2c /zip ffs rw,noauto 0 0</programlisting>
<programlisting>/dev/da0p1 /mnt ufs rw,noauto 0 0</programlisting>
