I'm sure sometime in the past few months I saw a snippet that HFS+ formatted drives risk serious directory errors when at over 85% capacity... maybe at MacFixIt? 15% is still a lot - too much in my opinion. Even if this is not true it _has_ helped convince me to make more frequent backups, which I've done for most of my files now. :) I've never gotten a complete answer on the value of defragmenting under OS X either. For the longest time I didn't think there _were_ any utilities to do this in X. Having never defragged my hard disk I shudder to think of what it looks like at this point. >OSX... has 80MB default no matter how much you have physical RAM, and >will add 80MB chunk of swapfile when needed. This is what I've read. Chris --
