[comp.sys.mac.misc] How come I can't "Erase Disk" my hard-disk?

MacII, Apple 40Mb hard drive.  I boot from floppy, clover-A to select
everything on my disk, drag to the trash, reboot from floppy just to
make sure, and then select the hard-drive, and try to select "erase
disk" and nothing happens ... Disk First-Aid says "unmount failed, can
not format", yet the drive gets unmounted.  PC Tools Deluxe or whatever
it's called greys out the menu item for "Format Disk" on the hard
drive.  What the heck?
