[comp.sys.mac] Odd 6.0 bug

I just came across yet another bug in System Software 6.0 that I haven't seen
mentioned elsewhere:

I toasted one of my hard disks and wanted to reinitialize it with HD SC Setup
(this was on a Mac II).  Well, HDSCS won't let you init a mounted volume, right?
So I dragged it to the trash and proceeded to initialize it with HDSCS.  I quit
back to the unifinder and was presented with two (!!) icons for that disk:  a
normal SCSI disk icon and a FLOPPY disk icon.  Both icons had the same space
available, etc, and copying to one put the object on both.

I duplicated this error with a debugger loaded and took a look at the drive
queue and VCB lists.  The dual entries were identical (important stuff
like driver and volume reference numbers too).
