No. I'm up in NW Ontario in Canada actually, far away from any salt 
water. I'm guessing it was from the combination of air 
pollutants/humidity and heat given the drives are not in the most 
hospitable environment esp during the summer ... but after cleaning the 
board contacts up as well as the esata cable ends/ports, its working 
great again.
I'm beginning to think when I do replace any drives, after warranty is 
up on them, pull off the PCB, clean it up and coat the contacts with a 
good smearing of dielectric grease to keep the issue from happening.
Makes me wonder how many other people out there suffer from the same 
issue given the amount of unresolved similar hw errors I've found while 
googling the errors..
Thanks again,
Andrew
