Like Tiger, Leopard does some dynamic defragmentation built-in. That would tend to keep areas clear BUT does not do it by explicit intention. It's mostly just trying to keep individual files contiguous and put the OS-critical stuff in the "middle" of the drive where it can be accessed fastest. > > Just out of curiousity - why are you partitioning the internal >> drive(s)?

In the classic OS days, we recommended such because it reduced disk corruptions. Today, in Mac OS X, it actually impedes things. HFS+ Journaled is a very robust/safe file system. And with the background defragging that the system does... dividing your HD too much makes it MORE difficult to optimize things. I strongly recommend using a *single* partition on your internal drives. As for Classic... The basic system folder is perfectly happy living on the same volume with OS X. In fact, that is the recommended configuration. If you need to actually boot on OS 9 *then* you might want to consider a separate partition for it *IFF* you have a lot of 3rd party extensions that you need. The idea here is to keep Classic Mode clean, because it's mostly incompatible with 3rd party extensions. Whereas a separate booted OS 9 volume lets you get as messy as you want.

The dynamic re-partitioning is something Apple added to facilitate the creation of a Boot Camp volume. Even their tech notes talk about preferring to do the re-partition when the machine is brand new -- BEFORE the data has moved around much. It is the type of operation that will NEVER EVER be trustworthy, no matter how you spin it. - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
