On Monday night, SuperDuper attempted to do two jobs at once, and got itself into a state that finally crashed. As soon as the application closed I got a message saying that the startup disk is full. Sure enough, when I got info on the HD, there was zero kb available - a couple hours earlier I checked this and there was around 6gb free on a 55gb hard drive in my Intel CD Mini. Since then, although the system works, I can't obviously do very much - I can't save anything, copy anything to my external HD, pretty much anything except surf the web (and even that not fully - Firefox has no back button available, although the backspace key still works!) I've ordered a 200gb HD that should be here in the next day or so, but in the meantime is there any way of regaining the lost space? I tried running Disk Utility from the Leopard disc when re-booting, and that gained me all of 24mb - is that the equivalent of re-booting a Windows machine with the XP disc in and doing a full Windows repair, or is there another step I can try? I'm loath to do anything too tricky, as my backup disappeared when SuperDuper crashed out, so don't want to lose all my pics etc. Any ideas?
