SSD auto erases when pro comes from sleep/hibernation mod.

Hallo! Help me)

I am using macbook pro 13" 2011 i5. So i bought ssd to upgrade my mac. It's plextor 128gb m6pro. I cloned all system from hdd to ssd. Also i bought optibay, i broke my hdd cable, so now all system is working on optibay and ssd (no hdd).

I have one serious issue. When i close macbook and then open after a few minutes my system starts to work not correctly so i click reboot system, and then blinking folder with question. I did like this for 4 times, other times system just doesn't open when i open my macbook. Then i go to the internet boot -> disk utility and see that ssd is fully erased, no partition!! I really don't know what to do.

It seems that it connects with optibay because it uses cd, sleep/hibernation mode and sittings.

Please help me!=)
