Ide folder created on xp - ownership issue on 7

Hi,

- I have a IDE Hitachi HD, from my old computer that use to run with XP 32.

- Now i have a Windows 7 64 on a Toshiba.

- I'm trying to get the folders from the IDE disk, and i already have changed the ownership authorization,

- But it stills prompting the message that i need Administrator authorization to delete and copy some stuff (most of it); even after i've re-connect it.

There's any alternative method?

Thanks

(Note: the printscreen its in Portuguese, but says access denied, you need administrator authorization to delete this file)

Yes they are diferent! i've stoped using the XP hd last year, and i didn't need the files until now.
I don't remember the old password at all.

Any sugestions to get over this?
