Hi, I have a powerbook G4 (pre-intel processor) that a few days ago froze in the middle of work, since then whenever I boot to it I get a grey screen after a few seconds and nothing else. I tried booting to the installation disk and running repair disk from disk utility, it gave an error and wasn't able to complete. I ran "verify disk" from disk utility, which ran indefinitely, I manually stopped the verification process and it gave the same error as I got when running "repair disk" (unfortunately I didn't write down the specific error but it seems irrelevant at this point considering what is to follow...) Afterwards I tried running disk rescue II, which doesn't even recognize my internal HD, only the CD it boots from. And now when I go back into disk utility from the installation CD, it doesn't recognize the internal HD anymore either. Is there anything at all left that I can do myself to recover the data from this thing? Other than paying untold amounts of money for professional recovery... Thanks in advance.
