He's back -- Fraggie's back

[Guest Fletcher James]

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.:cool:
