Hard Drive Issues (Both new and old)

I'm trapped in a HDD nightmare with my MacBook Pro mid-2012.

I updated to Yosemite 10.10.3 (with the Photos app). A couple of days after the update, I was watching a movie on my TV screen via HDMI. In the middle of the movie I removed the HDMI cable from the MacBook Pro and everything freezes. I forced shut down (Note: My HDD was encrypted). After I forced shut down, I tried to turn on and the loading screen would never stop loading - like, 14 hours stuck with the progress bar. Since I have backups, I decided to access DU and format my HDD. I tried everything. For real. Every command line I could type on Terminal to format, repair, erase and/or partition. I read almost every issue-related questions on the forums and stack exchange groups for a week (even posted my issue here: http://apple.stackexchange.com/questions/181090/erasing-and-partitioning-hard-dr ive-from-internet-recovery?noredirect=1#comment215695_181090).

So, I decided that it was a HDD failure and bought a new one.

I bought the Seagate 1TB SSHD Hybrid - ST1000LM014. Installed the new fresh disk and guess what? All those same problems again. I´m not able to restore from Time Machine because it doesn't recognize the disk in the restore page. But the disk is recognized in the DU. When I try to erase or partition the new SSHD, the same old errors: File system formatter failed. Yes, I tired GUID Partition Table, all of the security options, etc. 😟

Please. Any light that you can throw at this issue, I'll be very grateful for. BTW, the new SSHD is recognized and the SMART Status says: Verified.

Any ideas on *** is going on?

Thanks in advance!
