That is true of any drive that is mounted, whether it's just a partition or a separate physical drive. My question is, if you partition a drive, with OS X on one and OS 9 on another, don't those files stay within the designated partitions? A while back, I had both on one partition. A 20 gig drive. It's a Rev. D 333, and they require that the OS files reside within the first 8 physical Gigs. After running software update, the updater placed the new system files outside of the 8 Gig. It refused to reboot in OS X. However, I could reboot in OS 9, so I was able to back up everything. I then partitioned the drive into three parts: OS X, OS 9 (both inside the first 8 gig), and Everything Else for the remainder and reinstalled. All of the OS files have remained within their respective partition, and I haven't had a problem since, and have updated OS X a few times now. Nothing "jumps" from one partition to the other, unless I'm copying files from one to the other, but they are all accessible to the other mounted partitions. (Not counting when OS X "updates" some files in OS 9 when you first launch Classic. It would add files to OS 9 wherever it resides on a writable drive, mostly those ".ds store" files and such as OS X needs to run Classic.) Doesn't partitioning tell the computer that a given partition resides from 'this' physical sector to 'that' physical sector, and the next partition resides from 'the next' physical sector to 'whatever' physical sector, and so on to the end of the drive? And that when writing files to a particular partition, it would place them in the first available space within that reserved "drive" space? Otherwise, what would be the point of partitioning a drive? A simple folder could serve the same function if that's not how it works. Can anyone elaborate on just how partitioning actually works?
