Windows 8 Windows 8 admin/standard user access issues

My friend recently bought a new Windows 8 laptop which she set up in her name and therefore has a passworded Admin account. I also partitioned the HD so that the smaller portion (C) contains the OS and the larger portion (D) is for all her files.

Since I am only using the laptop temporarily my passworded 'standard' user account is located in (C) and cannot be viewed by anybody else, however, I can view my friend's files which are now being stored in 'D'.

Is there a way to protect the files in the 'D' partition in the same manner as if all accounts were on one drive and password protected?

Tom.
