Find a scheduled task

Hi,
I am not able to find a task that I scheduled some time ago. The task runs CHKDSK on an external drive. It ran OK today at logon. I want to see if I have a similar task scheduled for the "C" drive.
I looked in Task Scheduler and I can't find it.
The event viewer log dutifully reported the results in Windows logs > Applications > Wininit
Can you help me find it?
Thanks

I may have triggered the CHKDSK by using the Disk Properties tool "Check Volume for Errors" where I get the option to run chkdsk at the next logon.. Thus, I would not find it in Task Scheduler but I would find the results in Event Viewer.
