The title shows my latest discovery in the epic 4 day battle to swap out my mid 2009 unibody 15" MBP HDD for a 240 GB PNY SSD. In order below, the steps I have taken to get to this point:


- Formatted SSD using Sabrent SATA USB3 cable to mac OS X journaled

- Loaded formatted drive into computer and attempted to load OS X via a bootable El Capitan USB drive

- Drive will not boot, but is recognized when booting using the option button.

- Get prohibitory symbol when attempting to load SSD from option boot

- Tried installing a time machine backup to the SSD without success.

- Swap drive and replace original HDD which works fine (not fine, but its previous baseline slowness)

- SSD is operable via SATA USB cable and can boot into SSD drive via option boot if plugged in via USB.

- Successfully cloned the original HHD to SSD using carbon copy.

- The SSD shows prohibitory symbol after cloning and attempting to self boot into said SSD.

- Updated OS X on old HDD and created NEW El Capitan bootable thumb drive based off of latest updates.

- Formatted SSD again and loaded into computer. Booted into OS X installer

- Run installer and go through EULA. Load for ~60 minutes then auto restart due to install process

- When rebooting automatically during install, recovery page loads from usb and prompts to start install as if not installed (drive manager says otherwise)

- Try install again overnight and again, same outcome. On install reboot it starts from scratch, not picking up the fresh install.

- All throughout this process when not selecting the drive to boot from it goes to prohibitory sign unless original HDD is installed. Never have I seen the question mark file folder sign.

- Booted into command-S and received the following:

Error loading kernel cache (0x6)

ERROR!!! Recovery Image verification fail with status [0x8000000000000006]


I have not been able to boot to recovery mode

I have not been able to boot to safe mode


I have hit the end of the road short of chucking the computer. The HDD is so slow I cannot even watch a 15 second youtube video. It is almost non-functional with the original 2009 drive.


The SSD works since it will take an install (somewhat) and is able to be booted into via SATA USB3 cable.

The internal SATA cable is good because the old HDD works in its baseline state with it and I can install (somewhat) OS X onto it from the thumb drive installer.


Does anyone have anything else I can try short of buying a surface pro 4?

I was able to boot into verbose mode after installing another fresh install of OS X on the ssd via USB cable. It still won't boot off the internal SATA cable nor can I force boot into the drive or recovery partition via option boot.


The pic is what I got briefly in verbose mode before it restarted again into the prohibitive symbol. Is it the ssd drive after all?

OK, if anyone is watching this thread, here's a second update.


On the advice from someone on Reddit, I installed OS X from my original DVD of leopard. It worked and booted but only after the prohibitory, question file and apple logo flashed for about 5 seconds. I then upgraded a couple times and installed snow leopard from an upgrade disk I had. The snow leopard install had the same issue of flashing icons before booting into the SSD. Once the OS booted, finder wouldn't load until I cleared the error about 10 times. I can't open any app directly, only through spotlight.


I downloaded DriveDx and ran the quick free self-test and that came up clean, however under the "problem summary" section, there are 9 "current power cycle I/O errors."


Running disk repair gives a clean scan, but the file permissions always come up with repairs and the never resolve no matter how many times I run it.


At this point I am assuming it is purely a disk issue. I am going to attempt to return to amazon, and if that doesn't work I'll contact PNY.
