cant defrag

when i open xp defarg and hit analyze or defrag it does nothing,thried installing power defrag and the same thing happens then i tried to install diskeeper lite and when installing i get this error 1920.service diskeeper failed to start verify that you have sufficient privileges to start system services,im using computer admin account?i tried to check te drive(disc)for errors and when i reboot and it starts checking it says cant open volume for direct access?

What ‘same thing’?

Are you using an account with admin privileges or not?

Really? After you boot you can’t access the drive at boot time to check the disk? Hmm…

same thing meaning when i hit defrag it does nothing does not defrag,i only have 1 user account on this pc and it says computer adm does that mean i have adm privileges?yup after i boot and try to check disc for errors cant access it?

Yes, you have admin rights.

Is there any error message?
