Sounds like something may actually be trying write something to the disk while the defrag is running, some sort of malware perhaps?

@A4000_Mad

Firstly, don't use anything Symantec/Norton. Besides which, I've done plenty of defrags with Symantec AV running no problems, must be something your doing thats upsetting it. BTW, all journaled file systems require a check of some kind if power is cut suddenly, it's all part of trying to protect your data. Ever shut an Amiga off during a disk write?

Sounds really strange, perhaps you could download a live CD and defrag that way? Or even better, take a look at the 3rd party defrag tools.
