    kierand macrumors newbie

    My Macbook Pro was running absolutely fine until I tried transferring a 10GB file from an external disk drive. It froze 3 times and each time I had to switch the power off on my machine to restart (it's at this point I gave up trying to transfer but I wish I'd given up earlier!)

    Shortly after my machine started freezing, and after this happening about 3 times my machine won't get past the grey apple logo/spinning wheel.

    I've tried booting from my Snow Leopard CD and Disk Utility found no problems, so I decided to try reinstalling Snow Leopard. It starts installing and when it gets to about 20% it says it doesn't have enough memory, then shows what it's trying to install on and it's the below - the hard drive seems to have vanished after showing before...screengrab attached.

    Any ideas? Any help much appreciated.

    I can hear the disk spinning as it tries to boot but it's still just sitting on the grey apple logo screen...
