Can't edit my post anymore, but I wanted to add: Not all external drives respect the operating system's preferences. So even though you told OS X (or Windows for that matter) to not put your hard disks to sleep, the drive's firmware could overwrite that and go idle regardless. This explains why unchecking "Put the hard disk(s) to sleep when possible" doesn't solve the problem for everyone.
I actually went into the external drive's settings via WD software and told it to disable to the sleep timer along with going into the OSX energy saver preferences and unchecking that box. You did have a good point which is true about it not solving the problem for everyone. From what I've found in internet and other forum searches is that certain things have resolved it for some while other things have solved it for other people.

Have you tried researching this in their own support forums? You're probably not the only person having this issue and they may have offered a solution. If you do find one, come and share it here!
That actually was going to be my next shot. I actually hadn't gone there yet only because I thought maybe OSX was at fault (I was only guessing) but, I will be going to WD support forums and seeing what I can find out.
