defraggler scheduled task for c: drive freezes when /ts is added to cmd

I setup a scheduled defrag of my windows 2000 server c: drive and it automatically puts a /ts at the end of the cmd like this:

"C:\Program Files\Defraggler\df.exe" C: /ts

When the scheduled task runs it locks up the system, however, if I run the same scheduled task without the /ts it seems to work. I can't find any reference to the /ts in the docs, can someone please tell me what this is for and if there is a solution?

Thanks,

John

Hi,

this option is for the internal use of Defraggler. It allows to schedule several defrags at one time.

As there is only one Defraggler instance allowed, this option tell the Time Schedule instances to wait for other to finish. Without that option the scheduled instances started later would just quit.

Best regards
