I really agree with Alexis here. I was unaware that Apple does not support multiple HFS partitions on a physical device for the Mac OS. We use so many 3rd party drives around here that, we just assumed that everyone could get as many HFS partitions/physical device as they wanted. Have pity on the poor souls who use Apple as their only source. This really is a deplorable situation. The desktop file really bogs down when the number of files on an HFS partition gets above a few thousand. I even ran into a situation once when I was unable to create any new files when I reached about 3500 files on the partition. The machine just froze with its little watch icon spinning and I had to reboot. So what is a user to do if he/she has a large hard disk and several thousand small files. Well StuffIt would help by combining the files into archives, but this may not be an ideal solution for all users. One could use SilverLining or similiar partitioning software. Or one could buy lots of small hard disks from Apple at twice (or more) the going market price. Come on folks at Apple. ONE OF AN OPERATING SYSTEM'S MAIN FUNCTIONS IS TO EFFICIENTLY MANAGE FILES AND FILE STRUCTURES. UNIX is very popular because over twenty years ago the people at Bell Labs realized this and wrote an operating system with this in mind. Because of this foresight UNIX is a very expandable OS. We run it here at NASA on supercomputers and mass storage systems (with the ability to handle over a terabyte of data!) I read in MacWeek all the great things System 7.0 will provide the MacOS community (hot links, etc.), but I haven't read anything on improvements to the MacOS file system. Even modifying HS Setup to allow multiple HFS Partitions per physical device would be a help. But no - it seems Apple is intent on putting on several layers of frosting before they have finished baking the cake.
