Let me first start by thanking anyone who may be able to assist... My mid-2009 MBP recently started freezing up while it was sleeping which required me to hold the power button down to shut it off for a reboot. This happened 3 times in as many weeks. The last time it did this, it did not come back :-( I have went into the recovery utility and ran disk repair on the HD - there were no issues detected (that is a good thing) but the computer still would not boot. I then decided to bite the bullet and do a fresh install of Lion (using the USB bootable flash drive that I had made). I booted the computer into the recovery utility, wiped the HD (without issue) and installed Lion (without issue - or so I thought). While Lion was installing, it said it would automatically reboot the computer when finished but it did not - I did this manually once the progress indicator had disappeared but no luck - the computer booted to the recovery utility (on the flash drive). I removed the flash drive and then got the "no file system" flashing folder icon with a question mark in it. So... I thought it must be the HD - today, I just received a new WD Scorpio Black 320GB HD and installed - the disk utility sees it fine, I formatted it, installed Lion (again) but it still will not boot to it :-( At this point, I thought it must be the SATA cable so I removed the HD, connected it to USB (via an adapter I have) - the computer does not find it... Is there something I am missing or do I now just have a $1200.00 aluminum paper weight??? I am a PC guy and this MBP was my first forray into Mac-dom and am getting a little dis-heartened as I can usually figure this stuff out but this one has me completely stumped... Thoughts? Thanks so much in advance for your time!
