[comp.sys.mac] Copy protection of Master Tracks Pro

ts@cup.portal.com (Tim W Smith) (02/16/90)

Master Tracks Pro is a nice program with obnoxious copy protection.
The copy protection is the kind that allows you to install two
copies on hard disks.

It appears to work by creating an invisible file that records the
blocks that MTP occupies.  If you make a copy, this no longer
matches, and it won't run.

I've found a couple of ways to deal with this.

	1. During installation, it checks to see if the floppy is
	write protected.  It won't let you install from a write
	protected floppy ( it needs to write to the floppy to
	keep track of how many copies you've installed on hard
	disks ).

	However, it only checks the write protect status of the
	floppy once.  If you pop the floppy out and write protect
	it when you get the SFPutFile dialog, you can still install
	without losing one of your installations.

	Note that you must pop the floppy without the Mac knowing
	about it.  Use the eject hole, not the eject button in
	the dialog.  An alternate method is to write protect the
	floppy when you insert it, but have a piece of paper
	covering the hole so that the drive reports that the
	disk is write enabled.  Slide out the piece of paper
	after MTP checks the write protect status.

	2. Make a 200k partition with HD Partition from SUM.  Install
	MTP on this partition, using the methods in #1 to avoid
	losing an installation from the floppy.

	Now, when you want to make a copy of MTP, use Disktools or
	something similar to copy the whole partition.  Or use
	ResEdit to make the file that HD Partition creates visible,
	and then the Finder can be used to copy it.

	Since you have made an image copy of the partition, it
	will not trigger the copy detection in MTP.
