    External 120Gig firewire Hard drive became locked during one of the several swelling battery failures on my 17" MacBook Pro.

    System info:
    Mac Book Pro 17"
    2.16 GHz Intel Core Duo
    2 GB 667 MHz DDR2 SDRAM

    I have done the best I could with the available threads. Drive is still locked. I may be missing a critical step in the process. Is it possible for someone to walk me through it?

    Unlock Hard drive

    I took the laptop and hard drive to the mac Genius bar and they tried a few lines of code in the Terminal app they got from the mac rumors forum. Besides selecting the Hard drive icon on the desktop and the command+I for get info and them trying all possible read and write options with no success, one of the Terminal code was something like this:

    cd /Volumes
    chflags -R nouchg Portable\ HD
    drag my hard drive's icon into the Terminal window then hit ENTER

    The Drive remains locked. It does NOT request password, I just get the following window:

    The folder “Mike misc” can’t be opened because you don’t have permission to see its contents.

    how to unlock external HD

    Hello please help.
    I had computer meltdown and had to reformat the drive and reinstall system software. I have MacPower book 2.8 Ghz/ system version 10.6.3.
    when I go to reinstall my documents/applications from my external firewire hard drive ( LaCie) , I get an error "you don't have permission to see its contents". The fact is that I never had a password or ever locked the drive.
    So I did use the command as mentioned in the thread earlier
    (chflags nouchg /Volumes/Media\ Drive
    sudo chmod 1775 /Volumes/Media\ Drive
    echo "done")
    I get the following message and then asks for a password ??

    drwxrwxrwt@ 5 root admin hidden 170 9 sept 12:36 .
    drwxrwxrw-t 29 root admin - 1054 9 sept 11:37 ..
    drw-rw-r-T 36 root admin uchg 1292 1sept 11:40 mac Os X Install disc 1
    lrwxr-xr-x 1 root admin - 1 9sept 11:36 Macintosh Hd -> /
    drw-rw-r-T 51 root kuldipmalhotra staff ucgh 1802 1 sept 11:28 Untitiled 2

    Thanks for any help to get my documents and backed up files back.
