    I recently purchased a Samsung SSD 840 EVO 250 GB to speed up my Mid 2010 MacBook Pro.

    Initially, I placed the SSD in the SuperDrive bay and set it as the primary drive. It worked well. Then I was told that it would be better suited for the HD bay (would be faster), and so I swapped the two drives.

    Now though, upon startup, I have the Apple boot up screen, but it changes the Apple logo eventually to a "no" symbol.

    I tried holding the "option" key on boot up a second time, and selected my SSD as the disk to boot from, but arrived again at the "no" symbol screen. I'm wondering if anyone can weigh in on possible issues? Should I just return it to the SuperDrive bay and be done with it? Can a Mid2010 MacBook Pro recognize the speed increase from putting it in the HD bay?

    So I put the SSD back in the SuperDrive bay and the HD back in it's original bay, and the same problem arises.

    I have now tried to zap the PRAM, and arrive at this screen:
    So seemingly, there are a few options I could take... a fresh install of an OS onto the SSD, or trying to see if I can repair one of the disks...

    My backup for the HD is the SSD, cloned with Carbon Copy Cloner. So whatever my next move is, one of the drives is expendable. Any thoughts on what my next step should be?

    Still not sure what is causing this and feel like it could be a more simple solution.

    My solution will cost you an additional $25.

    1. Take the SSD -out- for now, and restore the MacBook to its original configuration. Will it boot this way?

    2. Get one of these:
    or, one of these:
    or, this:

    3. Put the SSD into the dock, connect it to the MacBook, turn it on

    4. Launch Disk Utility (in the Utilities folder) and initialize the drive to HFS+, journaling enabled.

    5. Download CarbonCopyCloner from here:
    CCC is FREE to download and FREE to use for 30 days.

    6. Launch CCC and clone the contents of your internal HDD to the docked SSD.

    7. Once the clone is complete, TEST IT. Reboot and hold down the option key until the startup manager appears. Select the docked drive, and hit return.

    8. If you get a "good boot" (look around to be sure everything is as you wish), NOW it's time to open up the MacBook and "do the swap"...

    Thanks Fishrrman for your suggestions. Here's what I ended up doing:

    I booted into safe mode and scanned the two drives, after putting the HD in it's original bay. There was an error of some sort found with my original HD, so given that I own a copy of CCC already, and that the SSD was a clone of the HD, I wiped the HD and reformatted it.

    Good as new. Now I have no problems.
