    Thanks !!! It worked for me

    All you have to do is to:

    - download CentOS 5.2 Live CD ISO
    - burn the ISO with ImgBurn
    - bootup your Mac from CD called "Windows" (keep pressing Alt on startup)
    - open Linux console
    - type: sudo su
    - install some needed programs with yum -y install gcc make
    - download newest edition of hdparm with: wget http://sourceforge.net/projects/hdpa...ar.gz/download
    - unpack files: tar -xzvf hdparm*
    - go to hdparm directory cd hdparm*
    - type: make
    - then type: make install
    - type: /sbin/hdparm --yes-i-know-what-i-am-doing --dco-restore /dev/sda (if your SSD is a 1st drive, if second sdb, if 3rd sdc, if 4th sdd etc.)
    - if you see message:

    /dev/sda:
    issuing DCO restore command

    then it's OK

    - type: reboot

    This is like gibberish to me...and it sounds like a hassle. I have a MBP 2.0 Core Duo with Kingston 40GB SSDNOW V Series installed. Need TRIM support. Obviously don't have access to a PC. Anyone find a way to do this with a Mac? Anyone make a program or something to enable TRIM for this drive???
    Or can anyone explain or summarize the above procedure so I understand what's going on?

    Thanks Smart people~

    Bump

    I just ordered one of these and I really hope I don't have to do all that! Maybe load the iso in boot camp and I guess upgrade the firmware from there?

    Why bother? OS X doesn't support TRIM. Even if you enable it on that drive, nothing will change.

    Damn that sucks. Could you still get the benefits from TRIM by allowing it in Win 7 which supports TRIM?

    oh didn't know OS X (10.6.2) does not support TRIM

    did some research....
    thanks for reply.

    Well that settles it anyway, Kingston SSDNOW V Series doesn't even have TRIM enabled... Was looking to update the firmware and do stuff to it to enable TRIM...now that I know OS X doesn't even support it, it's pointless.
