    Hi Everyone,

    I have been searching the internet/ google for an answer to this, but my situation is as follows:

    1. Bought Microcenter SSD 64GB for boot drive (3 months ago). From my research it is a rebadged A-Data Sandforce
    2. Installed and worked beautifully in Mac Pro.
    3. Installed the Trim-Enabler for 10.6

    Doing lots of Xcode4 and Aperture.

    One day, I left the computer idle for a fews hours, came back, woke it from sleep. Had a beach ball effect, the beach ball would stop, and everything was super slow, then beach ball again. After 20 minutes of beach ball, I decided to shut down computer with the power button. Upon reboot, drive no longer recognized by the Mac...

    I took the drive out and put it in an external enclosure, tried all my other computers (Macbook Pro, Windows Box). Nothing, won't get recognized. I got the drive apart and just stuck the pcb board directly to a SATA connector and saw a green light go on, so I know the drive is getting power.

    Is there anything I can do???? I would send it away, but it has some important data in it I want try and recover first. (Mostly Pix and some Code).

    Thanks for any help!

    This is why I tell everyone one the forum buy intel.

    Not to say I told you so but most likely all is lost.

    MY track record with sandforce is 6 good out of 9. Corsair 2 for 3 patriot inferno 2 for 3 AND ocz vertex 2 for 3. all of them were for raid0 all of them came as a pair all of them had 1 good and 1 bad. All of the rmas were good. all of them were 20 percent slower then specced to be. all were sold be different real sellers. newegg mwave superbiiz

    sandforce has done this in many other ssds !

    request a quote. it will cost more then a hdd recovery.

    Never ever ever ever ever let a sandforce ssd go to sleep it may not wake up. This problem has occurred time and time again. Here is what I would do go to the ocz forum and look up sleep issues with mac and vertex2 or vertex3. I have not been there since last year as all mty vertex gear has been sold off.

    Maybe someone has a fix no one had a fix as of dec last year. Ocz sells a lot of sandforce maybe some got it to work with the freeze it for 24 hour trick then clone it with superduper. I think two people out of hundreds said this worked.

    Unfortunately, it seems like the drive is dead (there are a lot of problems with Sand Force based 6.0Gb/s SSD's right now, and likely the newer Sand Force 3.0Gb/s SF-2100 series models as well).

    As per getting the data off of it, I don't see how the freezer trick will even work, as that's based on the mechanics of HDD's, not the electronics. So I expect your data is lost (why you need to keep a backup, no matter what your data is stored on for a primary location, including RAID). :(

    Thanks - I appreciate the feedback. I got a little lazy and didn't back up my stuff. Guess I'll just purchase a new drive from a different brand.

    I don't think the freezer trick will work, but two people on ocz forum wrote that it did in summer of 2010 many many tried it after the write up and said no luck. The first two may have just been trolling but it is free to try it. as for me intel from now on.

    Trolling is a definite possibility (or they flat out didn't know what they hell they were talking about). Either way, the odds of it working aren't good (expect it's actually zero). But as you mention, it's free and easy to do. So no harm done if someone does give it a shot. ;)

    But Intel is definitely the safe bet right now, though the Samsung 470 seems to be around the same territory (still not sure which one has the better reliability rating).

    Both beat the pants off of OCZ and Corsair right now. OWC still seems to be an oddball/unknown to me, as there's not the history of complaints other than the sleep issue, which may have been sorted since the newer firmware release for their SSD products (rev. 360). But it would still deserve some caution IMO, so I'll stick with the current recommendation of Intel or Samsung.
