You have probably noticed that sometimes the Mac runs out of memory and tells you it is throwing out one or more disks. When you throw away a disk icon, you are merely freeing the RAM that was holding the disk's directory. Since the disk still has a (?) faithful copy of it's directory, you can read it back in if desired, and there is therefore no need to allow you to take it back out of the trash (except, perhaps, for consistancy...). Which reminds me, there were some bugs in the old version of the finder (haven't checked the new one yet) related to throwing disks away. You could modify the INFO entry for a file on a disk that is not in the drive at that time, throw away the disk icon, and never have the INFO recorded. In this case, the finder should ask you to reinsert that disk before allowing you to throw it away or only let you change INFO entries on the currently inserted disk. -Jon Spear -------
