I am using a Ubuntu LIVE USB to boot my laptop. However, after I enter the system, I am able to see my C: drive.

Question: Is it possible that I can completely block the access of the internal hard drive from accessing through the Ubuntu?

Thank you

You can dismount the device. Of course this also means you can mount it. This of course also would require sudio permissions or if not I am sure it can be configured to be. –  Ramhound Sep 11 '13 at 16:54
    
How can I dismount the internal hard drives? –  q0987 Sep 27 '13 at 14:44
    
@qq0987 - Just use umount and mount. I would look up the command to understand the required syntax required to use it of course. –  Ramhound Sep 27 '13 at 15:09
    
Unmounting does not solve the ops issue –  Bruno9779 May 23 at 16:30

The only way to prevent access to a disk, to someone that has physical access to it, is encrypting it.

Depending on what system(s) is installed on the disk you want to protect, the software and the difficulty of encrypting will vary.

How so? The only way to prevent access to a disk when you have physical access to it, is encrypting it. The OP didn't state what system is on the disk he wants to protect, so, all he asked has been answered –  Bruno9779 May 23 at 16:58
