4 Page 3-120. Floppy disks can now be formatted
with either 8 or 10 sectors per track. If you
want to make a backup copy of your UNIX PC
system software, you should first format your
floppy disk(s) to contain 10 sectors per track.
a Point to I Floppydiskl in the Office and
press <Enter>.
b Point to IFloppy Disk System Format (10
sectors) I and press <Enter>.
c Insert the blank floppy disk that is to
be formatted and follow the instructions
on the screen.
Note that the Floppydisk menu entry, IFloppy
Disk Regular Format (8 sectors) I, is identical
to the IFloppy Disk Format I function that was
used in version 3.5 and earlier versions.
In making backup copies of the system software,
note that the GSS Drivers and GSI VDI are
formatted 8 sectors per track.
For any application software where the format
of the disk is unknown, you can quickly
determine its format:
a Place the floppy disk in the drive.
b Flip the drive lever down.
c Open I UNIX System I from the Office window.
d Type: iv -t /dev/rfp020 <Return>
This will give you a complete description of
the disk. Look for "8" or "10" on the line
that identifies the number of physical sectors
per track.
