Windows 7: Scheduled defrag query

06 Oct 2012   #1

Windows 7 Pro 64 bit
Scheduled defrag query

I ran Defrag from the start menu and it complained that the task was already scheduled.
In Task Scheduler I deleted the current Microsoft>Windows>Defrag scheduled defrag task and ran the Defrag program from the start menu again, thinking at that time of using an all manual approach.
Later, within the Defrag program I set up a scheduled defrag, selecting the C: drive and de-selecting 'Recovery'. I then looked at that task in Task Scheduler at Microsoft>Windows>Defrag.
The action produced by the Defrag program as seen in Task Scheduler is -
%windir%\system32\defrag.exe\\?\Volume{207b4d24-02e8-11e2-a875-806e6f6e6963}\ -e
I did run this task 'on demand', it took 11 mins with the disk activity light twinkling reassuringly and the History shows it to have been successful returning code 0.
Two questions arise -
Why such a peculiar Drive identification ?
Why is the switch '-e' used , which this tutorial identifies as meaning 'except for' ?
Can/should I create my own task(or modify Defrag's), with the scheduled action to be simply
%windir%\system32\defrag.exe C: ?
Also for interest what was the switch -i in the equivalent task under Vista ?
Regards, Tom
