I have a SCSI disk driver that works fine under systems before 6.0.
With 6.0, there are several problems:

	1. Choosing "Erase Disk" from the Finder brings up a
	dialog asking if I want to make this a single sided
	or a double sided disk.

	2. Dragging the disk to the trash from the Finder does
	not unmount the disk.

	3. Calling DIZero from an application to initialize the
	disk fails.  DIZero returns error -108.  The same application
	running under system 4.2 initializes the disk as expected.

Problem #1 only happens to disks using my driver.
Problem #2 occurs both with my driver and Apple's driver.
I forgot to check #3 under Apple's driver.

Before anyone asks, I can't give away my driver.  It is based on source
code from a driver a friend of mine did under contract to someone else,
and I obtained that source because I helped test his driver.  Thus, my
driver is derived from his, and can't be given away.
