After Windows 7 is installed, drive D cannot be accessed!

There is no problem during installation on a computer. During the installation process, the system automatically saves some of the original files as old files, which can also be reassuring. But this is the case that no problem occurs. This problem occurs: I put all my efforts on the D Drive. After the installation is complete, the D Drive is "inaccessible" when it is opened ".

First calm down, use other startup tools, open the D disk in NTFS format, and check that all the files are there. This gives me peace of mind. If it is too big, just export the files. After being calm, I began to study the cause of this problem. It was estimated that it was a permission issue. As a result, after the settings, the D disk came back:

1. view attributes on drive D (My problematic disk), select the "Security" tab, and click the "advanced" button below;

2. Select "edit" from "owner ";

3. In the displayed window, select the user name to be set and select "Replace sub-container and object owner" at the bottom ";

4. Select "application" and select "yes" in the system prompt. The system starts authorization;

5. Close all windows and open the computer windows. The D disk can be used.
