Need help finding a USB enclosure that will spin down drive on inactivity

I need help finding a USB hard drive enclosure that will let a WD20EARX green drive spin down after a few minutes of inactivity like the drive is designed to do. I’ve tried two USB 3.0 enclosures that don’t allow the drive to spin down when using USB. The enclosures also have eSATA and the drive does spin down appropriately when I connect the enclosure that way. The enclosures I’ve tried are the Rosewill METAS and the Vantec NST-330SU3-BK.

I found references where others said some of the newer USB 3.0 enclosures had this issue. Here’s one example:

I’ve read where others are having issues with the drive not spinning down after powering off the host system. That isn’t the issue I’m trying to solve – my issue is getting the drive to spin down due to inactivity.

I have an older 2.5” Toshiba USB external drive that does spin down after a few minutes like it’s designed to when connected to the PCs I’ve been testing this on, so I don’t think it’s a setting in Windows. I tried the USB 3 enclosures attached to a Ubuntu 10.04.04 system also and it never spun down there either. I’ve logically dismounted (“safe to remove” in Windows jargon) the drive in question but kept it physically connected and it never spins down when connected to a USB port. Once I pull the USB cable, the drive spins down.

The spin down functionality of this power saving green drive is built into the drive and functionality is not provided by the OS or the enclosure. But for whatever reason, the enclosure interface isn’t allowing this to happen.

Does anyone know if all external USB 3.0 enclosures exhibit this issue? Have you had better luck simply using a USB 2.0 enclosure? I’d like to have USB 3.0 because one machine I occasionally will be using actually has USB 3.0 ports and transfers data about 2.5 times faster (the Ubuntu machine I tested), but my main use right now is on an older machine with 2.0 ports, so I could settle for a USB 2 enclosure if I knew it would work.

I haven’t been able to find anything conclusive on what USB enclosures will allow this drive to spin down. I’m reluctant in ordering a 3rd enclosure (maybe USB 2.0) until I can get a pretty good sense that it will work the way I want it to. Thanks in advance!

I too am looking for such an enclosure that supports spin down and also 4TB drives. I have a Macally USB 2.0 enclosure which spins down after 5 minutes but max is 2TB:

This one supposedly supports 4TB and also spins down:

If you found something please let me know which it is!

Thanks.

i have the same problem with a DELOCK USB 3 case and a WDC WD10 EADS-00L5B1 1TB drive...the bloody
thing is driving me nuts and using precious power and motor life time....a antique philips usb 2 enclosure with
a 500gb drive from the stone ages spins down perfectly when not used ... horray for modern technology...:( 

Drive doesnt enter sleep when computer is in sleep (windows 7 , z68 mainboard) , and hung up to my Fritz Box 7360
with NAS and USB spin down feature (including a test button ) it doesnt either...

I ended up getting this eSATA adapter from Best Buy (has a Sil 3132) when they where closing them out for $5 about six month ago. I know that won’t work for everyone unless you have a PCI Express slot, but it works well for me with the Rosewill enclosure I noted above. Drive spins down when not in use, which is what I was really after. You can still get that adapter on eBay and elsewhere for little money.
