SUGGESTION:
Can you spend, say, $20-30?
If so, get one of these gadgets:
http://www.amazon.com/s/ref=nb_sb_n...ords=usb3+sata+dock&rh=i:aps,k:usb3+sata+dock
(many items shown, they all work the same, just pick one you like that's cheap)
Then - open the LaCie enclosure, take the hard drive out, put it into the dock, connect the dock to the Mac, and turn it on. What happens next?
SUGGESTION #2:
If you ascertain that the hard drive mechanism itself has failed, I would recommend that you consider buying a usb3/SATA dock anyway, and then pick up a "bare" hard drive of your choice to go into it. These can be VERY handy devices to have around, especially if you need to swap out a drive now and then. You can boot from them, too.
why didnt i think of that thanks! Now that Im switching to mac mini from pc how would you suggest I organize the four external drives i have?
They all various shapes and sizes. Would you consolidate them all to one big drive like the WD My Duo and maybe a second for back up? Or would you assemble them all with something like this

I suppose if I move them all to other drive(s) then they become the back up. That is if the mini can access them. Which prob means I have to move them all anyhow right? The mini will be in different room than the WNDR3700 router. My situation sounds similar the OP. Also be using my appleTV in main TV room. Thanks.
