Uh uh. Pretty much the only way to lose data due to a hard drive failure is when the read/write head crashes into the drive platter (the most common hard drive failure). If anything else goes wrong, the drive platters can be put into a good mechanism and recovered.
We were talking about the WD 640GB drives which have 2 320GB platters and two read/write heads. If the drive was set up as "two drives" in a RAID1 configuration, if you had one head crash you could still recover all your data from the other platter.
I see. I still think having 2 separate drive is better. When the drive fails, you don't want to waste time to send the drive to a data recover service to move the platters into a good mechanism to recover your data. That will take days (weeks?) and $$$$. You want your data the next day. For that you need a separate drive. Just my humble opinion.
