Ok, so......... here's the story.
Copied a movie file to the HDD, watched about 10 minutes in, got a msg indicating that 'file could not be played'. Ok, weird... so I hit circle to get out of the message, nothing happening, well then I'll just turn off the system, hit the PS button "Turn off System".
Light flickers for a few seconds as per usual waiting to turn red, but the system isn't shutting down at all. Must've waited for at least an hour or more, until I had no choice but to switch if off from the back. Now here's the part where I am shitting bricks, on power-up HDD is corrupt (Shit!) so I have to restore it, once that's done it takes me back to the boot up screen (Ok... cool) and then BAM it completely locks up on the SCE sign.
Nothing I can do can prompt it back into life or advance to the user account menu, it doesn't turn off by hitting the power button on the front, so again it's gotta be turned off from the back. But again, I'm asked to restore the HDD and the problem repeats again & so I repeated process at least twice more before realizing that it's probably totally fucked.
