I've been handed a MBP from a friend of mine and was asked to see what is wrong with it. I've never played around with Mac computers before so I'm not quite sure what all I can do with it. The problem right now is that it will not boot up. It starts up to a grey screen with a little wheel spinning but never gets past that point. I've tried using the special commands at boot time ie: Safe Mode etc to no avail. I can hold the Option button and get an image of the Hard Drive (Boot Disk and Recovery Disk - I believe it said), but the wheel spins forever whichever I click on. I'm also able to start it in Verbose mode and I see, disk0s2: I/O error jnl: disk0s2: update_fs_block: error reading fs block # XXXXX! (ret 5) then it just starts scrolling endlessly something about (Hard to read): disk0s2: 0x6 (UNDEFINED) disk0s3: media not present so, I assume the Hard Drive is going or has gone bad, but I'm not sure. I spoke with the owner and he bought me an external HD, but without a copy of the OS on it, I believe it's useless at this point. Is there any way to create a boot disk/systems disk so that I can at least boot from the external HD to copy some files from the internal HD...retrieve some data? Also, I'm not sure about this but I have available a linux computer. Is it possible to connect this via USB to the MBP and mount it's HD for data retrieval that way?
