    Hello, i've recently had my SSD Samsung 840 replaced because after i brought my Macbook Pro to friends place my mac din't reboot showed Blinking Question mark Folder, i've tried plugging this SSD to my PC and it wont show it. So i'm not sure what could have caused this problem.

    So right now i have replacement so wandering should i enable TRIM on it? and if so, what is the best method, any recommendations?

    I thought TRIM was enabled by default for all SSDs after Lion came out?

    I've used TrimEnabler on both the 840 in my Mini and the one in my MBP since I installed the drives with zero problems.

    Shouldn't cause any problems!

    If you're worried you don't NEED to use it. I'm pretty sure the 840 has built in garbage collection.

    Personally use Trim Enabler.

    Have done on my Intel X25-Ms and 330 series as well as Samsung 830 and 840 series SSDs.

    TRIM *should* be enabled!

    See this thread:
    http://forums.macrumors.com/showthread.php?t=1507367

    The last post links to a German language article which apparently confirms TRIM should definitely be enabled from Samsung employee's lips.

    ...and may need re-enabling after any OS X updates or if you reinstall, as well.

    Hope this helps anyone unsure.

    I had TRIM enabled on my first samsung 840, but it died within a week. On my replacement SSD, I did not enable TRIM. It work just as fast, on windows and OS X. It's been a good 3 months without TRIM and it works fine.
