Aus diesem Grund kann FileVault nur aktiviert oder deaktiviert werden, wenn mindestens gleich viel Speicherplatz zur Verfügung steht wie Benutzerdaten zu verschlüsseln oder zu entschlüsseln sind. In vielen Fällen muss man seine Benutzerdaten deshalb teilweise auf externe Festplatten «auslagern» um FileVault aktivieren oder deaktivieren zu können – FileVault zeigt ansonsten eine Fehlermeldung an.

Before I copied my sparseimage FileVault container (/Users/$USER/$USER.sparseimage) to an external USB drive, after the reinstall I copied it back. Then I remembered that FileVault in OS X 10.5 uses a new format (as reported in FileVault doesn’t use Sparse-Images anymore) and thought better of it. The new format apparently splits the image into 8MB big chunks, called bands which should make deallocation of free space much easier. [...] […] Just upgraded to Leopard doing a clean reinstall.

That makes migrating back a bit tricky - or lets say: manual. Damn :-) It’s not possible to mount a sparsebundle with Tiger. That makes migrating back a bit tricky - or lets say: manual.

It would be interesting to see another cryptographic assessment of FileVault after Leopard is release.

TheMacHackers think this was done to make free space allocation faster.
