I'm trapped in a HDD nightmare with my MacBook Pro mid-2012.
I updated to Yosemite 10.10.3. 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: Erasing and Partitioning Hard Drive from Internet Recovery).
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 WTF is going on?
Thanks in advance!
MacBook Pro, i7, 8GB RAM, mid-2012, 13-inch.
