Conceder acesso à pasta do usuário na unidade externa

Recentemente, substituí o HDD do meu notebook por um SSD e reinstalei o Windows 7 no SSD. Eu comprei um caddy para o HDD "antigo", e posso inicializar com sucesso as janelas do SSD.

Eu posso ver o velho HDD como uma unidade externa; no entanto, não consigo acessar minha pasta de usuários. Quando tento abrir a pasta do usuário, recebo este erro:

Se eu clicar em Continuenada realmente acontece. A barra verde mostra e carrega (como "Estou recebendo seus arquivos!"), Mas quando chega ao fim, não consigo entrar na pasta.

Alguma ideia?

Você pode usar o comando takeown para apropriar-se das pastas do usuário e, assim, recuperar o acesso aos seus arquivos (ou a qualquer outro) no disco rígido antigo.

TAKEOWN [/S system [/U username [/P [password]]]]
        /F filename [/A] [/R [/D prompt]]

Description:
    This tool allows an administrator to recover access to a file that
    was denied by re-assigning file ownership.

Parameter List:
    /S           system          Specifies the remote system to
                                 connect to.

    /U           [domain\]user   Specifies the user context under
                                 which the command should execute.

    /P           [password]      Specifies the password for the
                                 given user context.
                                 Prompts for input if omitted.

    /F           filename        Specifies the filename or directory
                                 name pattern. Wildcard "*" can be used
                                 to specify the pattern. Allows
                                 sharename\filename.

    /A                           Gives ownership to the administrators
                                 group instead of the current user.

    /R                           Recurse: instructs tool to operate on
                                 files in specified directory and all
                                 subdirectories.

    /D           prompt          Default answer used when the current user
                                 does not have the "list folder" permission
                                 on a directory.  This occurs while operating
                                 recursively (/R) on sub-directories. Valid
                                 values "Y" to take ownership or "N" to skip.

    /?                           Displays this help message.

    NOTE: 1) If /A is not specified, file ownership will be given to the
             current logged on user.

          2) Mixed patterns using "?" and "*" are not supported.

          3) /D is used to suppress the confirmation prompt.

Examples:
    TAKEOWN /?
    TAKEOWN /F lostfile
    TAKEOWN /F \\system\share\lostfile /A
    TAKEOWN /F directory /R /D N
    TAKEOWN /F directory /R /A
    TAKEOWN /F *
    TAKEOWN /F C:\Windows\System32\acme.exe
    TAKEOWN /F %windir%\*.txt
    TAKEOWN /S system /F MyShare\Acme*.doc
    TAKEOWN /S system /U user /F MyShare\foo.dll
    TAKEOWN /S system /U domain\user /P password /F share\filename
    TAKEOWN /S system /U user /P password /F Doc\Report.doc /A
    TAKEOWN /S system /U user /P password /F Myshare\*
    TAKEOWN /S system /U user /P password /F Home\Logon /R
    TAKEOWN /S system /U user /P password /F Myshare\directory /R /A

Exemplo do Vista. Deve ser semelhante no Windows 7.
