Hi there, I'm having some trouble with my macbook not booting. It's 2.16GHZ white model from 2007 running leopard.

At first I was just getting a grey screen and nothing else, not even the startup sound. After resetting the PRAM i'm getting the flashing '?' folder when I just try to boot normally from the internal hard drive (320GB Hitachi).

When I boot from CD I can't see the hard drive in startup disk, but I can see the hard drive in disk utility, so I know it isn't completely dead. When I tried to repair the drive in disk utility I got the 'invalid B-Tree node size' error.

So, I completely erased the hard drive and successfully reinstalled OSX; or so I thought. It went through all the motions of a successful installation, at the end I was prompted to restart the machine as usual, and I did - except the machine wouldn't boot up and came up with the flashing '?' folder again.

I booted up in 'Apple Hardware Test' mode and did a complete test, no errors were found.

I am completely stumped, if anyone has any suggestions please post them.

Thanks

Your hard drive has gone south... (it's defective) and should be replaced. No amount of formatting and reinstalling is going to work. The invalid B-Tree node size error is fatal. As inexpensive as large hard drives are, just replace it.

Thanks for the reply. I'll install a new hard drive and see how it goes.

Cheers
