B-tree issues with internal hard drive and use of tech tool pro

Ive been reading for a long time now and my problem that i've seen a lot of people have still not solved for me. so here I go.

Attempting to boot up my macbook pro (leopard) - problem b-tree error
Tried start up disk - no
Tried holding down different combination of keys on boot up - no
Taken internal hard drive out placed it in newer macbook pro (lion) (replacing optical drive temporally). Installed tech tool pro 6
Run surface scan - passed
Attempted volume repair - failed.
Either I can't or Tech tool pro wont let me make a disk image (no option for faulty hard drive for the source)

Additional
I've a 250 external that i'm wiping as i speak.
Ive enough room on my macbook pro(lion) to copy all data over
Im not sure what i can do/ how to get about it.

please help thank you.
