    Also, trying to enable TRIM manually did NOT work (I already tried) as the drive is recognized as an Apple Drive and the TRIM enablers specify NON APPLE drives only.

     

    well, I don't know how trim enabler disables trim. two more questions:

    1) did trim enabler run at all and if so what exactly it tells when you tried to enable trim?

    2) did you disabled trim (revert or how it is called there) in trim enabler after you tried to enable it?

    It's a Toshiba drive with Apple branding on it.

    all of them are, so its normal

    When I enabled TRIM with the enabler it said something to the effect of not supported. I disabled and re-enabled several times, also tried repairing permissions and nothing worked.

    I see 3 cases:

    1) not updated pre-boot parts of system - if so it will recover with Disk Utility repair

    2) trim enabler irrecoverably disabled trim in kext (small probability) - if so it will re-enable itself on next major system update or reinstall

    3) Apple SSD with early firmware edition without trim support. I don't know if there were ones, but it can be. If so - there should be firmware update for them at Apple site (good case) - or SSD firmware update was integrated in iMac firmware update (bad case)

    1) I'm hoping this is the case. I'm wondering if I need to even go as far as to reformat and delete and create a new partition to try this also.

     

    2) I tried reloading Mountain Lion a few times before I even tried the TRIM hack so I doubt this is the case. TRIM always showed as "No"

     

    3) This is the one that worries me

    no need to repartition. DU on whole drive will re-write everything if needed.

    Yes I will try to repair later.

     

    I just looked at Apple Support downloads and I'm completely up to date on all EFI and Firmware.

     

    I also don't see any other downloads that would look like a Hard Drive Firmware.

     

    I wish I just bought a 3rd party SSD but I figured the Apple one would work best

    Hey, it works and its fast, yes? so just periodically give it possibility to do nothing hour or two for garbage collect do its deeds. Not a catastrophic thing.

    Every time you get something somewhere in world appears something better, so what? Next years ssd again will be better than this year best ones, thats a life.

     

    it works, fast and reliable - as well as yours MBP now - so go be happy

    I just tried doing the repair disk to both the partition and the disk. Both were OK. Still No to TRIM support though

    forget it. get a pleasure of SSD. In a year SSDs will be even cheaper and you'll get yourself new one.

    Be positive )

    Yes very true, this just bugs me ! Hahah

    200-Write

    203-Read


    Both according to BlackMagic Speed


    I'd imagine that's about the best for this drive being it's SATA II ?

    decent speed for your config. and as speeds are equal, drive is not weared

     

    ps. yesterday set 3x Vertex 4's in 3x MacPros, all 10.7.5 fully updated , one of drives didn't got trim enabled... On oldest MP.
