Every time I try to start defrag (or analyse) in XP, a window appears stating "defragmentor could not start". I have also tried installing Diskeeper as a workaround but that comes up with "diskeeper could not initialise". I have tried disabling Norton Internet Security and shutting down background processes to no effect....any ideas?!!
Many thanks to Gongoozler, there is a huge amount of info on the link. The problem for me was the paging file in Virtual memory, it was set to "no paging file", switching to the system managed setting cured it.
