Hi, I am writing about my friends computer. He has a Macbook Pro and the other day had an Iomega 500GB plugged into the 800 firewire port. He for some reason accidentally pressed down hard on the drive, heard a grinding sound and it was no longer recognizable by the MAC HD. So, he then consequently plugged in his other backup drive to begin to make a clone, which is a LaCie External, and that drive then got corrupted when he plugged it in. So now, no backup what so ever. Tonight, he went to an appt. with an Apple Genius Bar worker and they told him it was a coincidence and that once his Iomega was corrupted and he tried to boot the LaCie off of that, it corrupted the other drives too. He told my friend he has B-tree errors and needs data recovery on the external hard drives and that could be done. My question is can he do this himself with an $100 program or does it pay to bring it into someone? He doesn't have a lot of $$$ to spend unfortunately so that's the issue. If anyone has dealt with this problem and has had a satisfactory outcome, please do not hesitate to advise!
