defraging

Firstly, a little more information would be beneficial. But part of the reason could be due to interuptions to the process. Restart your computer in safe mode. If it is a 9x machine, press F5 during the boot up process. If it is NT/2000/XP press F8.Also it may be beneficial to run a scandisk. If it is an NT based system click start> run> type in 'chkdsk /r'
It will ask for it to start when computer is next rebooted. Allow it to do so and it will repair any problems it finds.

What is your OS?
Try defraging in Safe mode

Is your virus protection up to date? Run a virus scan before defraging the drive. Shut down all background programs before running "defrag" i.e. taskmon,printer tray, antivirus, disconnect from Internet shut down firewall. Leave "explorer" and "systray" alone. If it won't run all the way through then start looking for a virus.
Run a rescue disc set if you made one for your system. (Norton Anti-Virus) others?

Even when you start in Safe Mode, which is the best thing with the old Windows Defrag, remember to disable any screen saver and if necessary turn off any power saving options.

Most defragging problems, as stated above, are because the system writes to the disk, causing the defrag to start again, and again, and again!

As advised, it is a good idea to run scandisk if Win95/98/ME, or chkdsk if it is an NT/2000 system, before a defrag. This can also need a start in safe mode, particularly with 95/98/ME.
