Someone sent me an email which asked what to do since: one of my external hard drives, the one with EVERYTHING I REALLY, REALLY WANT on it has died

Last Friday at work my Mac (OS X 10.4) laptop HDD died. After the purchase of an extra external HDD and some custom recovery software, Data Rescue II, I tried to recover as much as I could. The bad news is the Hard drive had not just gotten corrupted, but failed. After an attempt to clone it to a second drive for analysis, and during my recovery attempt it developed the click of death.
