Will HD replacement fix the problem?
My late 2009 iMac, 11,1, 4core i5, 2.66 GHz, Mavericks, will only boot up in safe mode. It will not boot from a FW800 HD, or a USB HD, nor a OS 10.6.2 optical disk. It shows all of this with option restart, but just like the internal HD boot, all stop at the Apple logo gray screen.
This was a sudden event, away from home and returned to find frozen with black screen, would only start in safe mode. Repaired permissions and verified & repaired drive. Can boot a MBPro from this drive in target mode.
I used optical drive to run a hardware test. With short test: error code 4MOT/4/40000003:HDD-1248 or -1243.
With long test: error code 4MOT/4/40000003:HDD-1273 consistently.
SMARTReporter does not show problems (safe mode)
From what I read the error indicates HD needs replacing, but will replacement solve the problems?
Is this a good question?

I'm having the same problem.
Did you solved the problem?

did you install a temp & fan monitoring program to see whats happening? Did you clean out the dust buildup internally? More often than not the issue is heat is not dissipating correctly due to dust or blocked vents.
