A glitch in Lion? Had to reformat before drive would mount again

[Jessica Lares]

This morning I rebooted my MacBook Pro. It started trying to load a firmware update, which of course didn't exist because there wasn't one to begin with. So it hanged and sat there at 0% for about five minutes until I restarted it.

Then, it booted to the spinning indicator. Then I restarted it again, the Apple logo, then nothing.

I went into the Disk Utility app in the recovery, Macintosh HD was gray and it wouldn't mount until I erased the partition. It wouldn't let me repair or verify permissions.

I then proceeded to reinstall OS X. The download took two hours, 20 minutes to install. A nightmare.

Has anyone had this happen in Lion particularly?

I had exactly the same issue, yet after running memtest for 3 very long passes nothing was detected. I had to format the drive and reinstall Lion from a Time Machine backup. Yet, even after this I get some instances where the machine will not boot. I can turn it off and when I restart usually will boot. I did get rid of the 'firmware' like bar.

Have you had your logic board checked out?
