I like to keep my system leaned out and I keep a lot of services and processes turned off using System Profiles. Do you think I might have some critical process turned 'off' when it should be 'on' when running MyDefrag?
I don't know if there is a service that MyDefrag needs in particular but the Task Scheduler service for example is responsible for managing the prefetch files. (There is bug in MyDefrag that let's it crash when it encounters an old prefetch file)
I don't have a log. I never was able to get Debug configured to run appropriately for the recording of evaluation results- so that's why I resorted to JKDefrag.
Afaik MyDefrag creates a log when it crashes, independent of the current debug setting. Make sure that the directory MyDefrag is installed in has write permissions.
Even though my system is functioning normally now I'm very skid-dish now about re-running either program again.
Like I said, MyDefrag is pretty safe and just moves files around. There are only three things that can go wrong:
1. A bug in the Defragmentation API (XP SP3 is known to be stable, though)
2. A program expects a file at a certain location (like boot managers and encryption software)
3. Faulty hardware.
