I am a newbie, kinda, so please do not flame me here. I added a HD to my powermac. If I go to disk utility, it says mac os extended or standard? What is the difference?

Basically, Standard is the "old" format, and is really only there for if you need to use the same HD with an old system. Extended was added in Mac OS 8.1 and includes many improvements, including more free space (the minimum file size has been made smaller, so less space is wasted with small files). You should use Extended, unless you need to use the HD with a pre-OS 8.1 machine.

Mac Standard - HFS is similar to FAT16 in the windows world
Mac Extended - HFS+ is similar to FAT32 in the windows world
Unix File System (Not supported for most Mac stuff yet) - UFS is similar to NTFS in the windows world

Hope this helps

Just a note, FAT16/32 and HFS/+ are nothing alike in terms of actual File System, but the changes that happened between FAT16 and FAT32 are analogous to the changes between HFS and HFS+.

Has anyone out there gone all Unix-File-System? I'd like to, for the sake of NFS interoperability with other systems. I know that there have been glitches in the past. Surely they've gotten better by now, no?

I know a few people who have done it, but they have to have a seperate HD for all their Carbon and Classic Apps.

According to a friend of mine, when shareing a HD, nfs will be emulated if that is not what is being shared (Of course he was half-in-the-bag when he said that)

I chose extended when I set it up. I guess I guessed right! Thanks.

If I add a harddrive to my Mac, can I make it appear as if I only have one disk. For example, if I fill up my 40G drive with Movie projects, can I add a 160G drive and it effectively expands my "Macintosh HD". Like a symbolic like?
Can I point my "users" directory at the second disk?

Actually HFS+, IMO, is more like NTFS. Fat32 still has a 4GB limit, not so in HFS+. UFS is able to put same named files (different caps) which NTFS is not. Use UFS only if the external hd is going to be shared with Linux or Unix computers.

Actually FAT32 has a 2TB limit (According to fdisk), but ATA-100 has a 137GB limit, and ATA-133/166 250GB
I'm not sure about the limit of HFS+, but heard that you should not have drives over 20GB, and if you use Large files (>1GB) like those from VPC, you should use HFS, because of Faster Access (or so I'm told.) I'm not sure about the specs for NTFS or UFS, but I believe their big advantage is encrypting ability, more organized structure, and even faster response times.

To add a harddrive to you system an make it seam like there is just more space, you should be able to setup a RAID with Striping. I'm not sure if it was here, but a guy set up a 5MB drive bu RAIDing 5 Floppies together. I'm not sure about doing it after the fact, so do some research. BTW: OSX has build in RAID functioning.
