Can't defrag the "C" drive

Can't defrag the "C" drive

I have a dell laptop (10 months old running Windows 7).  When I try to run defrag I see the two external hard drives and the "D" recovery drive on the defrag window list.  The Disk clean up, analysis and defrag work fine for those drives.  I do not see
the "C" drive listed.  How do I get the "C" drive to show up on the defrag window list...?  I have the laptop set to defrage once a week.  I am now concerned that the "C" drive is not being defraged....perhaps for a long time now.  Any hints....?

Hello,
If this is an OEM computer, please attempt to run the hardware diagnostic test and verify the status of the HD.  In addition, please attempt to run Chkdsk /r /f.  Verify if you are able to see the drive in Disk Management.  How much free space do you have
on your HD?  You will need at least 15% free space to run the Disk Defrag.
Step 1:
Click on start and then type “diskmgmt.msc” (without quotes) and press enter.
Check if C drive is detected there.
If it is detected there then run a Check disk and see if it finds some errors.
