File size oddities Mac OS 8.6 PowerMac 8600

So, I'm sure I've read something related to this before, but I can't seem to find it anywhere. Basically, some strange things are happening with file and folder sizes on my PowerMac 8600 with a 73GB SCA SCSI drive (with adapter) running Mac OS 8.6. File sizes are humongous and shouldn't be. Here's an example:

A Word document that was 17kb on my Mac SE/30 is now 1.2MB once transferred to the 8600. The Office application folder is 1.2GB(!) when I know that the files themselves probably max out at about 300MB (probably less). I compressed a folder of random Word documents that was reported as being 2GB and the .SIT file registered as only 5MB (which is about right). So, any ideas on what's going on here? Many thanks!

Is the drive on the 8600 formatted as HFS or HFS+? It sounds like its formatted as HFS - this was something that used to happen with HFS and big drives, and was one of the reasons HFS+ came along. If you specifically need it to be HFS, make smaller partitions (like, say, no bigger than 2GB)

Yeah, that definitely sounds like HFS, which has larger cluster sizes (one of the causes of this problem). A similar problem occurred with FAT16, which is why MS introduced FAT32 (and eventually NTFS).

That being said, I agree with LCGuy. Use HFS+ if you can, and if you must have HFS Standard, keep the partitions small (technically, you could have 4 GB HFS partitions under Mac OS 8.6, but it's probably better to keep them around 2 GB or less for maximum compatibility).

Hey there. I think you're both correct. I used Drive Setup from the 8.6 disk, but clearly wasn't paying attention to the file system settings. I guess I just assumed DS would default to HFS+. I'll have a look and see if that's what happened and then report back. Many thanks!

UPDATE: Yep. That was precisely the problem. Drive Setup defaults to HFS, even on a Power Mac (an oversight, in my opinion). I'm now reinstalling 8.6 on a newly formatted HFS+ drive. Thanks again!
