I bought a samsung 1tb ST1000LM024 2.5" hard drive thats seems to be in working order.
I followed the numerous youtube videos in replacing the hard drive but it was a complete failure and for awhile i thought i bricked my ps4.
I made sure i got the full 1.51 update the 800mb one and not the 300mb one.
It reads the update off the usb stick just fine and when it reboots to install the firmware all i get is a blank screen with ps4 light pulsating blue.
I cant turn the machine off and i have to pull the power cord, i can still get into the recovery menu after a reboot and try again but the same thing happens.
The only way to get the machine to boot is to put the original 500gb hard drive back in and everything works fine.
So anyone know of any incompatibilities with certain hard drives?, or maybe the hard drive is just faulty.
I dont know, with the failure rate of these new consoles i dont want to keep messing with it :)
