He's back -- Fraggie's back

I posted earlier in the week about a Vista system which hung every night.
More tracing turned up the fact that when it hangs, dfrgntfs.exe is running
and taking exactly 50% of the CPU (the max which a single-threaded task can
use on a dual-core machine.)

dfrgntfs.exe is the defragmenter for NTFS volumes.

Yesterday evening, I went into task scheduler, and did everything I could to
disable this, including turning off Manual & Scheduled defrag runs. I also
told it NOT to run at next opportunity, if it missed its schedule, and to
cancel (and force cancel) if it ran for more than 4 hours.

A bit later, I saw this task running again! It could not be stopped through
Task Manager (it just wouldn't stop) so I re-booted, and left Task Manager
as my only running task.

This morning:
* ntfsdfrg.exe was running again
* it could not be cancelled
* the system was hung (clock unchanged since about half an hour after I
left)

Does anybody have any idea of why this is happening, or how to prevent it?

Sorry, I have no solution for your specific defragmenting predicament,
but in my experience, Vista's defragmenter can be a big headache. After
I got my Vista infested notebook recently, one of the first system
maintenance programs I loaded on it was the Diskeeper 2008 defragmenter.
It offers everything the Vista defragmenter lacks : predictability,
features, control, and performance.
