I have just installed a new 160 Gb disk in my Rev 1 (September 2003) aluminium G4 Powerbook. 45 minutes. It is an Hitachi drive. Unfortunately only 5400 rpm, as it replaced a Momentus 100 Gb drive which was 7200 rpm.... I used CCC to move my files over, which gave a disk with loads of free space (almost 50 Gb) After a few days, I got a message that my start-up disk was full !!! And it was, in that the free space was zero. It seems that the virtual memory is occupying 49 Gb of disk space. I can hardly believe it. In the old (pre 10.5.2) days, re-starting seemed to clear all the old swap files. Not any more. I am stuck with only 7 Gb free after re-starting. Any ideas of a way forward on this ? Has anyone else found this issue ? If I could get rid of the files, and regain my 45_ Gb, I would use Drive Genius to make a 20 Gb partition and use that for my virtual memory files. Any ideas or suggestions would be appreciated. regards, Trevor PS: the only benefit I have noticed from the massive 10.5.2 update is that my keyboard backlighting now works..... which is indeed useful when walking around my garden at midnight looking for a 3G signal to send my email.....
