The fact that it did transfer programs back and forth shows it was not spun down during THAT time. So who can say setting it for a few hours or even 5 minutes would not accomplish the same thing as NEVER? Someone with actual knowledge may step in as this problem is addressed in the future.
I tried the 5 hr. setting. Works until the drive goes to sleep and then you'll have the same problems. For right now setting to Never and unplugging when not in use or attaching to a switched power source seem to be the best solutions. Whether Running a drive 24/7 is a good idea depends on many factors such as drive design, environment, power stability/reliability etc.
