Put it to sleep, wait thirty seconds, then put your ear to it. If you can hear something that sounds like a fan, that would be your hard disk that hasn't properly spun down.

It spins down, I can hear it. But isn't the whole purpose for it to spin down while NOT in use, but the comp still is awake/active (ie web browsing)?
 
I spoke too soon. After sleeping my Macbook and letting it wake again, it refuses to sleep the hard drive again. It seems it only works straight from fresh boot, and it stops working after sleeping/waking the Macbook.

sab165 could you try this and see if it works for you or if sleeping the Macbook breaks it for you too?

When I first opened my MBP this morning my optibay did spin up, but I kind of expected that. After 3 minutes it spun down and is sleeping quietly as I type this post.

Wonder why it's not working for you?
 
Anybody try setting HDD sleep times? You can use the command line (Google it), or programs such as Cocktail do this too:



The time above is for inactivity, i.e. in the screenshot, the HDD is set to sleep after 30 minutes of being idle. I beleive in this instance, the time setting is disk idle time, not computer idle time.
 
For the record: I tried many things for like a week and a half, and couldn't find a fix for this. So I ended up buying the MCE Optibay, and am now using it. Problems fixed! I guess the Fenvi Optibay is cheaper for a reason... something must be going wrong on the logic board... Signals aren't being translated properly or something. Either way, fenvi = no sleep, MCE = sleep works perfectly. Also it's slightly quieter somehow, and the optibay is far more secure.
 
The first step I took was to disable Spotlight from indexing and searching the optibay drive.

How exactly did you do this? Also is there a terminal command that can tell the Macbook to look at the OpticalBay SATA first therefore bypassing the sleep issue involved with moving the SSD to that position?
 
My SSD is in my data doubler while my HDD is in the normal spot (everything OS X is on the SSD and storage/bootcamp is on the HDD). Not a single sleep or wake issue to report.

Why did you feel the need to put the OS X in the Optical Bay area and not the usual Apple position? Just curious as I'm debating getting a 1T for the doubler which would need me to have the same arrangement due to size.

HDD was already in the normal position, was too lazy to swap them.

You go in through System Preferences -> Spotlight -> Privacy and add the entire drive to the privacy setting.

Thanks. Thought that was the case but it haven't got the 2nd HD installed yet so the option wasn't there.

That is the same solution I proposed earlier in this thread. Thank you for the post though, as the instructions and pics are a bit more structured than mine.
