A hard disk attached to a LaserWriter IINTX gets initialized with 20% of
the disk space dedicated to font storage and 80% to font caching. The
LaserWriter Font Utility tells you how much space is available for
additional font storage.
The "diskstatus" operator gives the number of pages currently available and
the maximum number of pages available (a page being 1024 characters). The
operator "userdiskpercent" returns the percentage of disk space allocated
for user files.
The operator "setuserdiskpercent" allows you to set the percentage of user
file space on the drive. It also removes the least-recently used cached
bitmaps from the hard disk until there is enough free space available.
