Dzung,
  Look up the DRIVER.SYS in your DOS manual.  This will allow you to create a
Logical drive as a single sided drive.  A format of that logical drive will
create a single sided 360KB 3.5" disc.

Put something like this in your CONFIG.SYS file on your PC.
    DEVICE=DRIVER.SYS /D:1 /H:1
The other parameter defaults should be OK.  The /D: is the drive starting with
0 (1 = 2nd drive {B}).  The /H: is how many heads, thus 1 for 1.  This will
create the next logical drive available on your system.  If you have a hard
disk it will probably be drive D: if not drive C:.

Good Luck,
PjH
