Windows 7: Padlock file, with re-installed Windows 7 and moved hard-drive

Hi,

I have a box, which was freshly installed with Windows 7 on a new hard-drive.

A second hard-drive has been added, which is showing up as a drive letter.

The second-hard drive was from a prior disbanded Windows 7 installation.

The new Windows 7 I am on, is logged in as administrator.



However, when I try to access the old hard-drive, ... all of the files and folders are "padlocked" on the icons. Anytime I click on them, I have to painstakingly wait by clicking dialog boxes to get into the folders/files.

What is going on? I understand I am needed to do something to clear this up... but not sure.

If someone would be so kind, could they list a step by step tutorial that is Windows 7 friendly, that is sure to work to resolve this?

Thank you in advance & thanks a million.

Grace
