[comp.sys.mac.programmer] How can I have an HC stack check if it's running from a hard disk?

elliott@veronica.cs.wisc.edu (James Elliott) (04/14/91)

I have a HyperCard stack I'm creating as an entry for a contest, which
makes intensive use of sampled sounds. I would like to have it test to
see if it is being run from a floppy and warn the user that
performance will be miserable if that happens to be the case (because
floppy access mangles sound output horribly). How can I do this?

I'm willing to write an XCMD if someone can point me in the right
direction. If there's an easier way, though, I'd like to use it.

  In the startup script, put

  on openstack
     if the diskspace < 1200000 then
        -- either your hard disk is chock full and you need to
        -- do something else or warn the user of this possibility 
        answer "This needs to run on a hard disk" with
           "continue" or "quit"
      end if
   end openstack

This will not work on certain CD volumes which have zero K free.
Sounds played from the SCSI CD do nicely.
