MS Vista Home and Chkdsk of an external HDD

[RoConno]

A friend of mine powered off his computer while it was in the middle of an internet download of a printer driver. He wasn't able to boot up after that. It would just get part way into the Windows XP startup and then re-boot, over and over again.
We put his C: drive into an external USB enclosure and hooked it up to a laptop. We could see and access the HDD and were able to copy most of his Docs & Settings folder. I tried to create an image of his drive using Macrium Reflect Free and after it had completed about 90% of the drive analysis, an error message popped up saying there was a file problem and I was to run chkdsk E:/f. My laptop has Vista home premium and I opened a command window and entered chkdsk E:/f . It responded with a message that said something like you don't have enough privilege, you must be logged on as an administrator. Well, I was logged on as an administrator when I tried this. Does anyone know how to be more of an administrator than logging into an account that has administrators privileges?
Thanks for any help you guys can offer!

Right-mouse-click on the Command Prompt program and select "Run as Administrator". You now have permission to fully run Chkdsk.

Thanks for the reply RebateMonger. Did I get to the command window the correct way? From a Vista Home Premium User Administrators desktop, I clicked on Start, entered "Command" and it displayed "Command.exe" which I selected. It then brought up a black DOS type of window. Is it inside that window, that I should "Right-mouse-click on the Command Prompt program and select "Run as Administrator"?
Thanks again for the help!

I wasn't sure how to describe this. I'll try a different way:

/Start/All Programs/Accessories
How, right-mouse-click on the menu option "Command Prompt"
From the menu that pops up, select "Run as Administrator"

Now the black Command Prompt window will open. Type your command, "chkdsk e: /r" for instance, inside the black Command Prompt window.

Thanks for the fast response RebateMonger. I'll try it that way and let you know if it works.

You're the man RebateMonger. That worked like a charm. Thanks again.
