How can I gain a full access to files?

Question

Due to the extent system errors on my notebook, I decided to only reformat the drive of the Windows. Unfortunately, after reformatting from Windows XP to Windows 7 ultimate, I can't access now the other unformatted drives.

Then I discovered converting the HDD to an external HDD, I can see now the files. Yet, those files neither be copied nor opened and always returning a request for a user to access the folder (S-??-..., something like this).

With the said details above, how can I gain a full access on those said files?

Answer 1

Take ownsership of the files:

1. Right-click the file that you want to take ownership of, and then click Properties.

2. Click the Security tab, and then click OK on the Security message (if one appears).

3. Click Advanced, and then click the Owner tab.

4. In the Name list, click Administrator, or click the Administrators group, and then click OK.

The administrator or the administrators group now owns the file.
