Problem installing OSX

I'm fixing a friend's Macbook Pro.

It's a MD101T/A model.

I have configured it with a 1000 GB hard drive and a 120 GB SSD from Samsung (840 series). Both drives are new and working, I have tested them on other machines to be sure.

The computer isn't working anymore, I couldn't boot so I tried reinstalling OSX. I tried both internet recovery (which makes me install 10.7 even though I have bought 10.8, and I have tried installing from a USB flash drive with 10.8.4.

Nothing seems to work, I can't get to the end of an installation.

I tried saving the error log from my last installation but it says I don't have permission, I even tried sending it via email to Apple but still no permission. Anyways I keep getting the same error " hdiutil verify failed"

I tried running a hardware test, both normal and extended. No errors at all. Any ideas on what it could be? I am having trouble mounting the disks in target disk mode too. The drives come out in read only mode and I can't mount them.

Also a couple of times while booting with C pressed, the Mac couldnt' find the two hard drives, the only drive I could boot from was the USB key.
