When I went to Tiger I did an Erase and Install and in the process seemed to recover about 1GB of vanished disk space. Since then I have kept a notional track of my usage and seem to have about 0.5GB nibbled away somewhere. Clearing caches and so on has no effect. "Where is my Disk Space" gives a full audit but no clues, it is certainly not disappearing in large recognisable chunks. I am tempted to SuperDuper the whole lot across to another disk then from there erase and bring it all back again and see what I get but apart from the time involved I always see such operations as potentially risky. As I have only a 19GB boot disk which is about half full the loss of 0.5Gb or more is not useful.
Any comments welcome
