Windows 7: Problem copying files from XP disk to Win 7 PC

Hi all, I'm trying to transfer all my data from my old Windows XP PC to the new Windows 7 PC. What I did is I removed the main OS drive from my old XP machine and I connected the XP drive to the WIndows 7 PC as an external drive. I then copy/pasted all of the XP contents to a folder in the 2nd internal drive of my new Windows 7 PC. The "Documents and Settings" folder of the XP drive is about 11GB but it will transfer only 5GB to the Windows 7 PC because for some folders/files it will say:"You do not have permissions to modify this folder/file". I'm using Windows 7 as administrator with full rights and disabled UAC. I also tried to go to properties/security settings for the folder I'm trying to move without success. Any suggestions? Thanks.

Hiyya Antares I am not sure but perhaps the old drive data is only recognisng the old admin rights.

This may be of help "You do not have permission to modify files in this network - Microsoft Community

Take ownership of the XP drive to get past those permissions: Take Ownership Shortcut

From either there or the secondary HD pitstop, click Organize>Select All, then drag the collective contents of each sub-folder (Downlloads, Videos, Documents, Music, Pictures) to the corresponding Windows 7 User folder on the lefthand Explorer bar. Hold the left click until it expands and confirms copy location in hypertext, only then release the files.

If you plan to leave the XP files on the secondary HD, sort them into copies of the Windows 7 User folders you create there, then right click each to add to the related Windows 7 Library - Include a Folder - Windows 7 Forums.
