News: I found a "good" caviar 100gb HD. I swapped the logic boards. I was able to save my documents and address book.
I restarted the computer. It found "Errors" on the disk, and repaired them. Now, I cannot boot from that (The original) HD.
I reassembled the "good" 100gb HD, formatted it, and now use it as my primary HD.
My original HD is in an antistatic bag, awaiting the day I can rescue all my MP3s, movies, MAME stuff, etc.
Yes, I know HD manufacturers are a PITA when it comes to changing things. I think if I can find a logic board, I can use the drive as a slave drive, and extract the remaining docs.
There is nothing critical on it now, just things I would like to get back someday...
I'll post a pic of what a logic board looks like after shorting btw the 12v and ground on a computer PS...
