Hi, I am in a serious problem with my Mac book pro refusing to boot. Its a 17", bought in early 2011 with now mountain lion 10.08 installed in it. The problem started three days ago when in the middle of editing a project in final cut pro x, my system suddenly started crashing after installing the neat video program. It became worst that i had to reformat and reinstalled original os x. Then i was busy reinstalling back the programs until today when i started using it again. The first failure i had was in the morning when my external disk crashed and refused to come on ever after i repeatedly tried to fix it with disk utility. Then this evening the same final cut pro 10.08 crashed and the rainbow ring was just spinning for hours. I had no option than to just press the power off bottom after repeatedly trying the command option esc. when i started the system, the apple logo comes and a silver like ring follows which just kept on spinning and noting happened. I then placed in my original os disk and used the disk utility by verifying first and it said that i needed to repair the disk but that failed too. It ended up saying that the disk utility cannot repair this disk. Then when i start the machine the apple logo comes and a progress back under shows a progress line form the left to the right end and the whole system will switch off. I then tried to reboot pressing only the option key and selected the recovery option when the two hard disk were displayed. Unfortunately i tried to use the disk utility there too with first verifying and after was asked to repair, but that too failed. Is there any way i can fix this problem with out loosing my files. Please can someone help me out of this? I am suppose to deliver this film next monday. Thanks in advance.
