I'm assuming this issue with FileVault has been long, long resolved, but I wanted to make sure before I told my GF it was okay to reclaim.

Yes, you can reclaim disk space just fine.

Right when Panther was released FileVault could **** your whole system if you let it reclaim disk space when it asked.

That was a huge enough problem that I was sure it had to have been fixed by now, I mean, we're almost at the 9th rev. Still, I just wanted to check for sure.

So the upshot is, if your system is up to date, there isn't any problem at all.

On the other hand, I've heard that the OSX virtual memory swapfiles aren't encrypted, so you can grep them for the master FileVault password. I'm not too concerned because I figure the schmuck who steals my (or my GF's) laptop won't know how to do this. I certainly don't know how.

I'd seek a different solution if you have something to be genuinely paranoid about. For me it's more about denying aforementioned schmuck the satisfaction of rifling through my stuff.

Still easier just to create an encrypted disk image on your hard drive using Disk Utility and keep any sensitive files in there.

yes. true.

but i'm lazy, don't you get into situations where when every time you reboot to do something then you have to double click an alias? then type in your password etc...

I hate mouting stuff all the time.

Be aware that this is may be changing in Tiger. I don't remember if encrypted swapfiles will be optional or mandatory -I'm hoping for the latter- but I do remember hearing that they will be supported one way or another.

I don't remember hearing about that being added to the filters either, but then, I've always seen the term spelled with an e on the end, making it munge.

Anyway, I was apprehensive about FileVault at first myself, but I started using it on my PowerBook back in January, and I haven't had any problems with it yet.

I've got a Titanium Powerbook G4-400 and have been using file vault for over a year. No problems whatsoever -- and -- it's seemless to use and a great comfort knowing your sensititve and/or private data is secure.

I also seem to recall that the swap files get wiped each time the OS restarts. Like was mentioned, I'm sure if anyone steals my Powerbook, they will get the OS X CD, reset the password, then log in and create a new user. There are very few people that know how to get to the invisible swap file and know how to look at it to locate some password.

Right it might be easier but it's still not secure, your browsing, your preferences, and all sorts of data in your Library will still be readable to me. Some of the most damning "evidence" gets placed in your library...

That said, the new "Use Secure Virtual Memory" option is nice. I'm too afraid to really use filevault on a laptop. Or in tiger for that matter.

Well, if you're that anal. Anyway, my cache is deactivated, I can edit cookies and even reset Safari. Safari 2.0 will allow anonymous browsing as well.
As far as other items in the library, you can set Fruit Menu to clean recent lists or deactivate caches/lock folders.

But this is getting away from the orginal topic which was safely keeping files secure. And an encrypted disk image is as safe as anything you're going to use.
