"System Volume Information" is a system folder, so you can't open/delete it in NTFS partition bcoz you don't have permission to do so.
To delete/open it, you'll have to take ownership of the folder. Goto its properties and in "Security" tab, take its ownership. (If you don't get "Security" tab, then disable "Simple File Sharing option" in Folder Options).
You can also use following registry code to add "Take Ownership" in file/folder context menu, which will make your task easier.
